React Interview Questions and Answers

A list of top frequently asked React Interview Questions and Answers are given below.

  • General React Interview Questions

    1) What is React?

    React is a declarative, efficient, flexible open source front-end JavaScript library developed by Facebook in 2011. It follows the component-based approach for building reusable UI components, especially for single page application. It is used for developing interactive view layer of web and mobile apps. It was created by Jordan Walke, a software engineer at Facebook. It was initially deployed on Facebook's News Feed section in 2011 and later used in its products like WhatsApp & Instagram.

    2) What are the features of React?

    React framework gaining quick popularity as the best framework among web developers. The main features of React are:

    • JSX
    • Components
    • One-way Data Binding
    • Virtual DOM
    • Simplicity
    • Performance

    3) What are the most crucial advantages of using React?

    Following is a list of the most crucial advantages of using React:

    React is easy to learn and use

    React comes with good availability of documentation, tutorials, and training resources. It is easy for any developer to switch from JavaScript background to React and easily understand and start creating web apps using React. Anyone with little knowledge of JavaScript can start building web applications using React.

    React follows the MVC architecture.

    React is the V (view part) in the MVC (Model-View-Controller) architecture model and is referred to as "one of the JavaScript frameworks." It is not fully featured but has many advantages of the open-source JavaScript User Interface (UI) library, which helps execute the task in a better manner.

    React uses Virtual DOM to improve efficiency.

    React uses virtual DOM to render the view. The virtual DOM is a virtual representation of the real DOM. Each time the data changes in a react app, a new virtual DOM gets created. Creating a virtual DOM is much faster than rendering the UI inside the browser. Therefore, with the use of virtual DOM, the efficiency of the app improves. That's why React provides great efficiency.

    Creating dynamic web applications is easy.

    In React, creating a dynamic web application is much easier. It requires less coding and gives more functionality. It uses JSX (JavaScript Extension), which is a particular syntax letting HTML quotes and HTML tag syntax to render particular subcomponents.

    React is SEO-friendly.

    React facilitates a developer to develop an engaging user interface that can be easily navigated in various search engines. It also allows server-side rendering, which is also helpful to boost the SEO of your app.

    React allows reusable components.

    React web applications are made up of multiple components where each component has its logic and controls. These components provide a small, reusable piece of HTML code as an output that can be reused wherever you need them. The code reusability helps developers to make their apps easier to develop and maintain. It also makes the nesting of the components easy and allows developers to build complex applications of simple building blocks. The reuse of components also increases the pace of development.

    Support of handy tools

    React provides a lot of handy tools that can make the task of the developers understandable and easier. Use these tools in Chrome and Firefox dev extension, allowing us to inspect the React component hierarchies in the virtual DOM. It also allows us to select the particular components and examine and edit their current props and state.

    React has a rich set of libraries.

    React has a huge ecosystem of libraries and provides you the freedom to choose the tools, libraries, and architecture for developing the best application based on your requirement.

    Scope for testing the codes

    React web applications are easy to test. These applications provide a scope where the developer can test and debug their codes with the help of native tools.

    4) What are the biggest limitations of React?

    Following is the list of the biggest limitations of React:

    • React is just a library. It is not a complete framework.
    • It has a huge library which takes time to understand.
    • It may be difficult for the new programmers to understand and code.
    • React uses inline templating and JSX, which may be difficult and act as a barrier. It also makes the coding complex.

    5) What is JSX?

    JSX stands for JavaScript XML. It is a React extension which allows writing JavaScript code that looks similar to HTML. It makes HTML file easy to understand. The JSX file makes the React application robust and boosts its performance. JSX provides you to write XML-like syntax in the same file where you write JavaScript code, and then preprocessor (i.e., transpilers like Babel) transform these expressions into actual JavaScript code. Just like XML/HTML, JSX tags have a tag name, attributes, and children.

    Example

    1. class App extends React.Component {  
    2.   render() {  
    3.     return(  
    4.       
        
    5.         

      Hello JavaTpoint

        
    6.       
      
  •     )  
  •   }  
  • }  
  • In the above example, text inside

    tag return as JavaScript function to the render function. After compilation, the JSX expression becomes a normal JavaScript function, as shown below.

    1. React.createElement("h1"null"Hello JavaTpoint");

    6) Why can't browsers read JSX?

    Browsers cannot read JSX directly because they can only understand JavaScript objects, and JSX is not a regular JavaScript object. Thus, we need to transform the JSX file into a JavaScript object using transpilers like Babel and then pass it to the browser.


    7) Why we use JSX?

    • It is faster than regular JavaScript because it performs optimization while translating the code to JavaScript.
    • Instead of separating technologies by putting markup and logic in separate files, React uses components that contain both.
    • t is type-safe, and most of the errors can be found at compilation time.
    • It makes easier to create templates.

    8) What do you understand by Virtual DOM?

    A Virtual DOM is a lightweight JavaScript object which is an in-memory representation of real DOM. It is an intermediary step between the render function being called and the displaying of elements on the screen. It is similar to a node tree which lists the elements, their attributes, and content as objects and their properties. The render function creates a node tree of the React components and then updates this node tree in response to the mutations in the data model caused by various actions done by the user or by the system.


    9) Explain the working of Virtual DOM.

    Virtual DOM works in three steps:

    1. Whenever any data changes in the React App, the entire UI is re-rendered in Virtual DOM representation.

    React Interview Questions1

    2. Now, the difference between the previous DOM representation and the new DOM is calculated.

    React Interview Questions2

    3. Once the calculations are completed, the real DOM updated with only those things which are changed.

    There is a lot of memory wastage in The real DOM.There is no memory wastage in the virtual DOM.

    React Component Interview Questions

    14) What do you understand from "In React, everything is a component."

    In React, components are the building blocks of React applications. These components divide the entire React application's UI into small, independent, and reusable pieces of code. React renders each of these components independently without affecting the rest of the application UI. Hence, we can say that, in React, everything is a component.


    15) Explain the purpose of render() in React.

    It is mandatory for each React component to have a render() function. Render function is used to return the HTML which you want to display in a component. If you need to rendered more than one HTML element, you need to grouped together inside single enclosing tag (parent tag) such as

    , , etc. This function returns the same result each time it is invoked.

    Example: If you need to display a heading, you can do this as below.

    1. import React from 'react'  
    2.    
    3. class App extends React.Component {  
    4.    render (){  
    5.       return (  
    6.          

      Hello World

        
    7.       )  
    8.    }  
    9. }  
    10. export default App  

    Points to Note:

    • Each render() function contains a return statement.
    • The return statement can have only one parent HTML tag.

    16) How can you embed two or more components into one?

    You can embed two or more components into the following way:

    1. import React from 'react'  
    2.    
    3. class App extends React.Component {  
    4.    render (){  
    5.       return (  
    6.          

      Hello World

        
    7.       )  
    8.    }  
    9. }  
    10.    
    11. class Example extends React.Component {  
    12.    render (){  
    13.       return (  
    14.          

      Hello JavaTpoint

        
    15.       )  
    16.    }  
    17. }  
    18. export default App  

    17) What is Props?

    Props stand for "Properties" in React. They are read-only inputs to components. Props are an object which stores the value of attributes of a tag and work similar to the HTML attributes. It gives a way to pass data from the parent to the child components throughout the application.

    It is similar to function arguments and passed to the component in the same way as arguments passed in a function.

    Props are immutable so we cannot modify the props from inside the component. Inside the components, we can add attributes called props. These attributes are available in the component as this.props and can be used to render dynamic data in our render method.

    18) What is a State in React?

    The State is an updatable structure which holds the data and information about the component. It may be changed over the lifetime of the component in response to user action or system event. It is the heart of the react component which determines the behavior of the component and how it will render. It must be kept as simple as possible.

    Let's create a "User" component with "message state."

    1. import React from 'react'  
    2.   
    3. class User extends React.Component {  
    4.   constructor(props) {  
    5.     super(props)  
    6.   
    7.     this.state = {  
    8.       message: 'Welcome to JavaTpoint'  
    9.     }  
    10.   }  
    11.   
    12.   render() {  
    13.     return (  
    14.       
        
    15.         

      {this.state.message}

        
    16.       
      
  •     )  
  •   }  
  • }  
  • export default User

    19) Differentiate between States and Props.

    The major differences between States and Props are given below.

    SNPropsState
    1.Props are read-only.State changes can be asynchronous.
    2.Props are immutable.State is mutable.
    3.Props allow you to pass data from one component to other components as an argument.State holds information about the components.
    4.Props can be accessed by the child component.State cannot be accessed by child components.
    5.Props are used to communicate between components.States can be used for rendering dynamic changes with the component.
    6.The stateless component can have Props.The stateless components cannot have State.
    7.Props make components reusable.The State cannot make components reusable.
    8.Props are external and controlled by whatever renders the component.The State is internal and controlled by the component itself.

    For More Information, Click here.


    20) How can you update the State of a component?

    We can update the State of a component using this.setState() method. This method does not always replace the State immediately. Instead, it only adds changes to the original State. It is a primary method which is used to update the user interface(UI) in response to event handlers and server responses.

    Example

    1. import React, { Component } from 'react';  
    2. import PropTypes from 'prop-types';  
    3.   
    4. class App extends React.Component {  
    5.    constructor() {  
    6.       super();        
    7.       this.state = {  
    8.           msg: "Welcome to JavaTpoint"  
    9.       };      
    10.       this.updateSetState = this.updateSetState.bind(this);  
    11.    }  
    12.    updateSetState() {  
    13.        this.setState({  
    14.           msg:"Its a best ReactJS tutorial"  
    15.        });  
    16.    }  
    17.    render() {  
    18.       return (  
    19.          
        
    20.              

      {this.state.msg}

        
    21.              this.updateSetState}>SET STATE  
    22.          
      
  •       );  
  •    }  
  • }  
  • export default App;

    21) Differentiate between stateless and stateful components.

    The difference between stateless and stateful components are:

    SNStateless ComponentStateful Component
    1.The stateless components do not hold or manage state.The stateful components can hold or manage state.
    2.It does not contain the knowledge of past, current, and possible future state changes.It can contain the knowledge of past, current, and possible future changes in state.
    3.It is also known as a functional component.It is also known as a class component.
    4.It is simple and easy to understand.It is complex as compared to the stateless component.
    5.It does not work with any lifecycle method of React.It can work with all lifecycle method of React.
    6.The stateless components cannot be reused.The stateful components can be reused.

    22) What is arrow function in React? How is it used?

    The Arrow function is the new feature of the ES6 standard. If you need to use arrow functions, it is not necessary to bind any event to 'this.' Here, the scope of 'this' is global and not limited to any calling function. So If you are using Arrow Function, there is no need to bind 'this' inside the constructor. It is also called 'fat arrow '(=>) functions.

    1. //General way  
    2. render() {      
    3.     return(  
    4.         this.handleChange.bind(this) } />  
    5.     );  
    6. }  
    7. //With Arrow Function  
    8. render() {    
    9.     return(  
    10.          this.handleOnChange(e) } />  
    11.     );  
    12. }  

    23) What is an event in React?

    An event is an action which triggers as a result of the user action or system generated event like a mouse click, loading of a web page, pressing a key, window resizes, etc. In React, the event handling system is very similar to handling events in DOM elements. The React event handling system is known as Synthetic Event, which is a cross-browser wrapper of the browser's native event.

    Handling events with React have some syntactical differences, which are:

    • React events are named as camelCase instead of lowercase.
    • With JSX, a function is passed as the event handler instead of a string.

    24) How do you create an event in React?

    We can create an event as follows.

    1. class Display extends React.Component({      
    2.     show(msgEvent) {  
    3.         // code     
    4.     },     
    5.     render() {        
    6.         // Here, we render the div with an onClick prop      
    7.         return (              
    8.           this.show}>Click Me
       
  •         );      
  •     }  
  • });  
  • Example

    1. import React, { Component } from 'react';  
    2. class App extends React.Component {  
    3.     constructor(props) {  
    4.         super(props);  
    5.         this.state = {  
    6.             companyName: ''  
    7.         };  
    8.     }  
    9.     changeText(event) {  
    10.         this.setState({  
    11.             companyName: event.target.value  
    12.         });  
    13.     }  
    14.     render() {  
    15.         return (  
    16.             
        
    17.                 

      Simple Event Example

        
    18.                 "name">Enter company name:   
    19.                 "text" id="companyName" onChange={this.changeText.bind(this)}/>  
    20.                 

      You entered: { this.state.companyName }

        
    21.             
      
  •         );  
  •     }  
  • }  
  • export default App;

    25) What are synthetic events in React?

    A synthetic event is an object which acts as a cross-browser wrapper around the browser's native event. It combines the behavior of different browser's native event into one API, including stopPropagation() and preventDefault().

    In the given example, e is a Synthetic event.

    1. function ActionLink() {  
    2.     function handleClick(e) {  
    3.         e.preventDefault();  
    4.         console.log('You had clicked a Link.');  
    5.     }  
    6.     return (  
    7.         "#" onClick={handleClick}>  
    8.               Click_Me  
    9.           
    10.     );  
    11. }  

    26) what is the difference between controlled and uncontrolled components?

    The difference between controlled and uncontrolled components are:

    SNControlledUncontrolled
    1.It does not maintain its internal state.It maintains its internal states.
    2.Here, data is controlled by the parent component.Here, data is controlled by the DOM itself.
    3.It accepts its current value as a prop.It uses a ref for their current values.
    4.It allows validation control.It does not allow validation control.
    5.It has better control over the form elements and data.It has limited control over the form elements and data.

    27) Explain the Lists in React.

    Lists are used to display data in an ordered format. In React, Lists can be created in a similar way as we create it in JavaScript. We can traverse the elements of the list using the map() function.

    Example

    1. import React from 'react';   
    2. import ReactDOM from 'react-dom';   
    3.   
    4. function NameList(props) {  
    5.   const myLists = props.myLists;  
    6.   const listItems = myLists.map((myList) =>  
    7.     
    8. {myList}
    9.   
    10.   );  
    11.   return (  
    12.     
        
    13.         

      Rendering Lists inside component

        
    14.               
        {listItems}
        
    15.     
      
  •   );  
  • }  
  • const myLists = ['Peter''Sachin''Kevin''Dhoni''Alisa'];

    28) What is the significance of keys in React?

    A key is a unique identifier. In React, it is used to identify which items have changed, updated, or deleted from the Lists. It is useful when we dynamically created components or when the users alter the lists. It also helps to determine which components in a collection needs to be re-rendered instead of re-rendering the entire set of components every time. It increases application performance.

    29) How are forms created in React?

    Forms allow the users to interact with the application as well as gather information from the users. Forms can perform many tasks such as user authentication, adding user, searching, filtering, etc. A form can contain text fields, buttons, checkbox, radio button, etc.

    React offers a stateful, reactive approach to build a form. The forms in React are similar to HTML forms. But in React, the state property of the component is only updated via setState(), and a JavaScript function handles their submission. This function has full access to the data which is entered by the user into a form.

    1. import React, { Component } from 'react';  
    2.   
    3. class App extends React.Component {  
    4.   constructor(props) {  
    5.       super(props);  
    6.       this.state = {value: ''};  
    7.       this.handleChange = this.handleChange.bind(this);  
    8.       this.handleSubmit = this.handleSubmit.bind(this);  
    9.   }  
    10.   handleChange(event) {  
    11.       this.setState({value: event.target.value});  
    12.   }  
    13.   handleSubmit(event) {  
    14.       alert('You have submitted the input successfully: ' + this.state.value);  
    15.       event.preventDefault();  
    16.   }  
    17.   render() {  
    18.       return (  
    19.           this.handleSubmit}>  
    20.             

      Controlled Form Example

        
    21.             
    22.                 Name:  
    23.                 "text" value={this.state.value} onChange={this.handleChange} />  
    24.               
    25.             "submit" value="Submit" />  
    26.            
    27.       );  
    28.   }  
    29. }  
    30. export default App;

    30) What are the different phases of React component's lifecycle?

    The different phases of React component's lifecycle are:

    Initial Phase: It is the birth phase of the React lifecycle when the component starts its journey on a way to the DOM. In this phase, a component contains the default Props and initial State. These default properties are done in the constructor of a component.

    Mounting Phase: In this phase, the instance of a component is created and added into the DOM.

    Updating Phase: It is the next phase of the React lifecycle. In this phase, we get new Props and change State. This phase can potentially update and re-render only when a prop or state change occurs. The main aim of this phase is to ensure that the component is displaying the latest version of itself. This phase repeats again and again.

    Unmounting Phase: It is the final phase of the React lifecycle, where the component instance is destroyed and unmounted(removed) from the DOM.

    For More Information, Click here.


    31) Explain the lifecycle methods of React components in detail.

    The important React lifecycle methods are:

    • getInitialState(): It is used to specify the default value of this.state. It is executed before the creation of the component.
    • componentWillMount(): It is executed before a component gets rendered into the DOM.
    • componentDidMount(): It is executed when the component gets rendered and placed on the DOM. Now, you can do any DOM querying operations.
    • componentWillReceiveProps(): It is invoked when a component receives new props from the parent class and before another render is called. If you want to update the State in response to prop changes, you should compare this.props and nextProps to perform State transition by using this.setState() method.
    • shouldComponentUpdate(): It is invoked when a component decides any changes/updation to the DOM and returns true or false value based on certain conditions. If this method returns true, the component will update. Otherwise, the component will skip the updating.
    • componentWillUpdate(): It is invoked before rendering takes place in the DOM. Here, you can't change the component State by invoking this.setState() method. It will not be called, if shouldComponentUpdate() returns false.
    • componentDidUpdate(): It is invoked immediately after rendering takes place. In this method, you can put any code inside this which you want to execute once the updating occurs.
    • componentWillUnmount(): It is invoked immediately before a component is destroyed and unmounted permanently. It is used to clear up the memory spaces such as invalidating timers, event listener, canceling network requests, or cleaning up DOM elements. If a component instance is unmounted, you cannot mount it again.

    32) What are Pure Components?

    Pure components introduced in React 15.3 version. The React.Component and React.PureComponent differ in the shouldComponentUpdate() React lifecycle method. This method decides the re-rendering of the component by returning a boolean value (true or false). In React.Component, shouldComponentUpdate() method returns true by default. But in React.PureComponent, it compares the changes in state or props to re-render the component. The pure component enhances the simplicity of the code and performance of the application.


    33) What are Higher Order Components(HOC)?

    In React, Higher Order Component is an advanced technique for reusing component logic. It is a function that takes a component and returns a new component. In other words, it is a function which accepts another function as an argument. According to the official website, it is not the feature(part) in React API, but a pattern that emerges from React's compositional nature.

    For More Information, Click here.


    34) What can you do with HOC?

    You can do many tasks with HOC, some of them are given below:

    • Code Reusability
    • Props manipulation
    • State manipulation
    • Render highjacking

    35) What is the difference between Element and Component?

    The main differences between Elements and Components are:

    SNElementComponent
    1.An element is a plain JavaScript object which describes the component state and DOM node, and its desired properties.A component is the core building block of React application. It is a class or function which accepts an input and returns a React element.
    2.It only holds information about the component type, its properties, and any child elements inside it.It can contain state and props and has access to the React lifecycle methods.
    3.It is immutable.It is mutable.
    4.We cannot apply any methods on elements.We can apply methods on components.
    5.Example:
    const element = React.createElement(
    'div',
    {id: 'login-btn'},
    'Login'
    )
    Example:
    function Button ({ onLogin }) {
    return React.createElement(
    'div',
    {id: 'login-btn', onClick: onLogin},
    'Login'
    )
    }

    36) How to write comments in React?

    In React, we can write comments as we write comments in JavaScript. It can be in two ways:

    1. Single Line Comments: We can write comments as /* Block Comments */ with curly braces:

    1. {/* Single Line comment */}  

    2. Multiline Comments: If we want to comment more that one line, we can do this as

    1. /*  
    2.    Multi 
    3.    line 
    4.    comment 
    5. */ }    

    37) Why is it necessary to start component names with a capital letter?

    In React, it is necessary to start component names with a capital letter. If we start the component name with lower case, it will throw an error as an unrecognized tag. It is because, in JSX, lower case tag names are considered as HTML tags.


    38) What are fragments?

    In was introduced in React 16.2 version. In React, Fragments are used for components to return multiple elements. It allows you to group a list of multiple children without adding an extra node to the DOM.

    Example

    1. render() {  
    2.   return (  
    3.       
    4.         
    5.         
    6.         
    7.       
    8.   )  
    9. }  

    There is also a shorthand syntax exists for declaring Fragments, but it's not supported in many tools:

    1. render() {  
    2.   return (  
    3.     <>  
    4.         
    5.         
    6.         
    7.       
    8.   )  
    9. }  

    For More Information, Click here.


    39) Why are fragments better than container divs?

    • Fragments are faster and consume less memory because it did not create an extra DOM node.
    • Some CSS styling like CSS Grid and Flexbox have a special parent-child relationship and add
      tags in the middle, which makes it hard to keep the desired layout.
    • The DOM Inspector is less cluttered.

    40) How to apply validation on props in React?

    Props validation is a tool which helps the developers to avoid future bugs and problems. It makes your code more readable. React components used special property PropTypes that help you to catch bugs by validating data types of values passed through props, although it is not necessary to define components with propTypes.

    We can apply validation on props using App.propTypes in React component. When some of the props are passed with an invalid type, you will get the warnings on JavaScript console. After specifying the validation patterns, you need to set the App.defaultProps.

    1. class App extends React.Component {  
    2.           render() {}  
    3. }  
    4. Component.propTypes = { /*Definition */};

    41) What is create-react-app?

    Create React App is a tool introduced by Facebook to build React applications. It provides you to create single-page React applications. The create-react-app are preconfigured, which saves you from time-consuming setup and configuration like Webpack or Babel. You need to run a single command to start the React project, which is given below.

    1. $ npx create-react-app my-app  

    This command includes everything which we need to build a React app. Some of them are given below:

    • It includes React, JSX, ES6, and Flow syntax support.
    • It includes Autoprefixed CSS, so you don't need -webkit- or other prefixes.
    • It includes a fast, interactive unit test runner with built-in support for coverage reporting.
    • It includes a live development server that warns about common mistakes.
    • It includes a build script to bundle JS, CSS, and images for production, with hashes and source maps.

    For More Information, Click here.


    42) How can you create a component in React?

    There are two possible ways to create a component in React:

    Function Components: This is the simplest way to create a component in React. These are the pure JavaScript functions that accept props object as the first parameter and return React elements:

    1. function Greeting({ message }) {  
    2.   return <h1>{`Hello, ${message}`}h1>  
    3. }  

    Class Components: The class components method facilitates you to use ES6 class to define a component. The above function component can be written as:

    1. class Greeting extends React.Component {  
    2.   render() {  
    3.     return <h1>{`Hello, ${this.props.message}`}h1>  
    4.   }  
    5. }  

    43) When do we prefer to use a class component over a function component?

    If a component needs state or lifecycle methods, we should use the class component; otherwise, use the function component. However, after React 16.8, with the addition of Hooks, you could use state, lifecycle methods, and other features that were only available in the class component right in your function component.


    44) Is it possible for a web browser to read JSX directly?

    Web browsers can't read JSX directly. This is because the web browsers are built to read the regular JS objects only, and JSX is not a regular JavaScript object.

    If you want a web browser to read a JSX file, you must transform the files into a regular JavaScript object. For this purpose, Babel is used.


    45) What do you understand by the state in React?

    In react, the state of a component is an object that holds some information that may change over the component's lifetime. It would be best to try to make your state as simple as possible and minimize the number of stateful components.

    Let's see how to create a user component with message state:

    1. class User extends React.Component {  
    2.   constructor(props) {  
    3.     super(props)  
    4.     this.state = {  
    5.       message: 'Welcome to React world'  
    6.     }  
    7.   }  
    8.   render() {  
    9.     return (  
    10.       <div>  
    11.         <h1>{this.state.message}h1>  
    12.       div>  
    13.     )  
    14.   }  
    15. }   

    The state is very similar to props, but it is private and fully controlled by the component. i.e., It is not accessible to any other component till the owner component decides to pass it.


    46) What are the main changes that appear in React's ES6 syntax compared to ES5 syntax?/How different is React's ES6 syntax compared to ES5?

    Following are the most visible syntax we can see while comparing ES6 and ES5:

    require vs import

    Syntax in ES5:

    1. var React = require('react');  

    Syntax in ES6:

    1. import React from 'react';  

    export vs exports

    Syntax in ES5:

    1. module.exports = Component;  

    Syntax in ES6:

    1. export default Component;  

    component and function

    Syntax in ES5:

    1. var MyComponent = React.createClass({  
    2.     render: function() {  
    3.         return  
    4. <h3>Hello JavaTpoint!h3>  
    5. ;  
    6.     }  
    7. });  

    Syntax in ES6:

    1. class MyComponent extends React.Component {  
    2.     render() {  
    3.         return  
    4. <h3>Hello JavaTpoint!h3>  
    5. ;  
    6.     }  
    7. }  

    props

    Syntax in ES5:

    1. var App = React.createClass({  
    2.     propTypes: { name: React.PropTypes.string },  
    3.     render: function() {  
    4.         return   
    5. <h3>Hello, {this.props.name}!h3>  
    6. ;  
    7.     }  
    8. });  

    Syntax in ES6:

    1. class App extends React.Component {  
    2.     render() {  
    3.         return   
    4. <h3>Hello, {this.props.name}!h3>  
    5. ;  
    6.     }  
    7. }  

    state

    Syntax in ES5:

    1. var App = React.createClass({  
    2.     getInitialState: function() {  
    3.         return { name: 'world' };  
    4.     },  
    5.     render: function() {  
    6.         return  
    7. <h3>Hello, {this.state.name}!h3>  
    8. ;  
    9.     }  
    10. });  

    Syntax in ES6:

    1. class App extends React.Component {  
    2.     constructor() {  
    3.         super();  
    4.         this.state = { name: 'world' };  
    5.     }  
    6.     render() {  
    7.         return  
    8. <h3>Hello, {this.state.name}!h3>  
    9. ;  
    10.     }  
    11. }  

    47) What do you understand by props in React?

    In React, the props are inputs to components. They are single values or objects containing a set of values passed to components on creation using a naming convention similar to HTML-tag attributes. They are data passed down from a parent component to a child component.

    The main purpose of props in React is to provide the following component functionality:

    • Pass custom data to your component.
    • Trigger state changes.
    • Use via this.props.reactProp inside component's render() method.

    For example, let us create an element with reactProp property:

    1. <Element reactProp={'1'} />  

    This reactProp name becomes a property attached to React's native props object, which already exists on all React library components.

    1. props.reactProp  

    React Refs Interview Questions

    48) What do you understand by refs in React?

    Refs is the shorthand used for references in React. It is an attribute which helps to store a reference to particular DOM nodes or React elements. It provides a way to access React DOM nodes or React elements and how to interact with it. It is used when we want to change the value of a child component, without making the use of props.

    For More Information, Click here.


    49) How to create refs?

    Refs can be created by using React.createRef() and attached to React elements via the ref attribute. It is commonly assigned to an instance property when a component is created, and then can be referenced throughout the component.

    1. class MyComponent extends React.Component {  
    2.   constructor(props) {  
    3.     super(props);  
    4.     this.callRef = React.createRef();  
    5.   }  
    6.   render() {  
    7.     return this.callRef} />;  
    8.   }  
    9. }  

    50) What are Forward Refs?

    Ref forwarding is a feature which is used for passing a ref through a component to one of its child components. It can be performed by making use of the React.forwardRef() method. It is particularly useful with higher-order components and specially used in reusable component libraries.

    Example

    1. import React, { Component } from 'react';  
    2. import { render } from 'react-dom';  
    3.   
    4. const TextInput = React.forwardRef((props, ref) => (  
    5.   "text" placeholder="Hello World" ref={ref} />  
    6. ));  
    7.   
    8. const inputRef = React.createRef();  
    9.   
    10. class CustomTextInput extends React.Component {  
    11.   handleSubmit = e => {  
    12.     e.preventDefault();  
    13.     console.log(inputRef.current.value);  
    14.   };  
    15.   render() {  
    16.     return (  
    17.       
        
    18.          this.handleSubmit(e)}>  
    19.             
    20.             
    21.           
    22.       
      
  •     );  
  •   }  
  • }  
  • export default App;  
  • For More Information, Click here.


    51) Which is the preferred option callback refs or findDOMNode()?

    The preferred option is to use callback refs over findDOMNode() API. Because callback refs give better control when the refs are set and unset whereas findDOMNode() prevents certain improvements in React in the future.

    1. class MyComponent extends Component {  
    2.   componentDidMount() {  
    3.     findDOMNode(this).scrollIntoView()  
    4.   }  
    5.   render() {  
    6.     return   
    7.   }  
    8. }  

    The recommended approach is:

    1. class MyComponent extends Component {  
    2.   componentDidMount() {  
    3.     this.node.scrollIntoView()  
    4.   }  
    5.   render() {  
    6.     return  this.node = node} />  
    7.   }  
    8. }  
    9. class MyComponent extends Component {  
    10.   componentDidMount() {  
    11.     this.node.scrollIntoView()  
    12.   }  
    13.   render() {  
    14.     return  this.node = node} />  
    15.   }  
    16. }  

    52) What is the use of Refs?

    The Ref in React is used in the following cases:

    • It is used to return a reference to the element.
    • It is used when we need DOM measurements such as managing focus, text selection, or media playback.
    • It is used in triggering imperative animations.
    • It is used when integrating with third-party DOM libraries.
    • It can also use as in callbacks.

    React Router Interview Questions

    53) What is React Router?

    React Router is a standard routing library system built on top of the React. It is used to create Routing in the React application using React Router Package. It helps you to define multiple routes in the app. It provides the synchronous URL on the browser with data that will be displayed on the web page. It maintains the standard structure and behavior of the application and mainly used for developing single page web applications.

    For More Information, Click here.


    54) Why do we need a Router in React?

    React Router plays an important role to display multiple views in a single page application. It is used to define multiple routes in the app. When a user types a specific URL into the browser, and if this URL path matches any 'route' inside the router file, the user will be redirected to that particular Route. So, we need to add a Router library to the React app, which allows creating multiple routes with each leading to us a unique view.

    1. <switch>  
    2.       

      React Router Example

        
    3.       "/" component={Home} />  
    4.       "/about" component={About} />  
    5.       "/contact" component={Contact} />  
    6. switch>  

    55) List down the advantages of React Router.

    The important advantages of React Router are given below:

    • In this, it is not necessary to set the browser history manually.
    • Link uses to navigate the internal links in the application. It is similar to the anchor tag.
    • It uses Switch feature for rendering.
    • The Router needs only a Single Child element.
    • In this, every component is specified in .
    • The packages are split into three packages, which are Web, Native, and Core. It supports the compact size of the React application.

    56) How is React Router different from Conventional Routing?

    The difference between React Routing and Conventional Routing are:

    SNConventional RoutingReact Routing
    1.In Conventional Routing, each view contains a new file.In React Routing, there is only a single HTML page involved.
    2.The HTTP request is sent to a server to receive the corresponding HTML page.Only the History attribute is changed.
    3.In this, the user navigates across different pages for each view.In this, the user is thinking he is navigating across different pages, but its an illusion only.

    57) Why you get "Router may have only one child element" warning?

    It is because you have not to wrap your Route's in a block or

    block which renders a route exclusively.

    Example

    1. render((  
    2.     
    3.     /* ... */} />  
    4.     /* ... */} />  
    5.     
    6. )  

    should be

    1. render(  
    2.     
    3.       
    4.       /* ... */} />  
    5.       /* ... */} />  
    6.       
    7.     
    8. )  

    58) Why switch keyword used in React Router v4?

    The 'switch' keyword is used to display only a single Route to rendered amongst the several defined Routes. The component is used to render components only when the path will be matched. Otherwise, it returns to the not found component.

    React Styling Interview Questions

    59) How to use styles in React?

    We can use style attribute for styling in React applications, which adds dynamically-computed styles at render time. It accepts a JavaScript object in camelCased properties rather than a CSS string. The style attribute is consistent with accessing the properties on DOM nodes in JavaScript.

    Example

    1. const divStyle = {  
    2.   color: 'blue',  
    3.   backgroundImage: 'url(' + imgUrl + ')'  
    4. };  
    5.   
    6. function HelloWorldComponent() {  
    7.   return Hello World!
      
  • }  

  • 60) How many ways can we style the React Component?

    We can style React Component in mainly four ways, which are given below:

    • Inline Styling
    • CSS Stylesheet
    • CSS Module
    • Styled Components

    CSS Module is a CSS file where all class names and animation names are scoped locally by default. It is available only for the component which imports it, and without your permission, it cannot be applied to any other Components. You can create CSS Module file with the .module.css extension.

    62) What are Styled Components?

    Styled-Components is a library for React. It is the successor of CSS Modules. It uses enhance CSS for styling React component systems in your application, which is written with a mixture of JavaScript and CSS. It is scoped to a single component and cannot leak to any other element in the page.

    The styled-components provides:

    • Automatic critical CSS
    • No class name bugs
    • Easier deletion of CSS
    • Simple dynamic styling
    • Painless maintenance

    63) What are hooks in React?

    Hooks are the new feature introduced in React 16.8 version that facilitates us to use state and other React features without writing a class.

    See the following example of useState hook:

    1. import { useState } from 'react';  
    2. function Example() {  
    3.   // Declare a new state variable, which we'll call "count"  
    4.   const [count, setCount] = useState(0);  
    5.   return (  
    6.     
        
    7.       

      You clicked {count} times

        
    8.        setCount(count + 1)}>  
    9.         Click on this button  
    10.         
    11.     
      
  •   );  
  • }  

  • 64) What are the rules you should follow for the hooks in React?

    We have to follow the following two rules to use hooks in React:

    • You should call hooks only at the top level of your React functions and not inside the loops, conditions, or nested functions. This is used to ensure that hooks are called in the same order each time a component renders, and it also preserves the state of hooks between multiple useState and useEffect calls.
    • You should call hooks from React functions only. Don't call hooks from regular JavaScript functions.

    65) What are forms in React?

    In React, forms are used to enable users to interact with web applications. Following is a list of the most common usage of forms in React:

    • Forms facilitate users to interact with the application. By using forms, the users can communicate with the application and enter the required information whenever required.
    • Forms contain certain elements, such as text fields, buttons, checkboxes, radio buttons, etc., that can make the application more interactive and beautiful.
    • Forms are the best possible way to take inputs from the users.
    • Forms are used for many different tasks such as user authentication, searching, filtering, indexing, etc.

    66) What is an error boundary or error boundaries?

    An error boundary is a concept introduced in version 16 of React. Error boundaries provide a way to find out the errors that occur in the render phase. Any component which uses one of the following lifecycle methods is considered an error boundary. Let's see the places where an error boundary can detect an error:

    • Render phase
    • Inside a lifecycle method
    • Inside the constructor

    Let's see an example to understand it better:

    Without using error boundaries:

    1. class CounterComponent extends React.Component{  
    2.  constructor(props){  
    3.    super(props);  
    4.    this.state = {  
    5.      counterValue: 0  
    6.    }  
    7.    this.incrementCounter = this.incrementCounter.bind(this);  
    8.  }  
    9.  incrementCounter(){  
    10.    this.setState(prevState => counterValue = prevState+1);  
    11.  }  
    12.  render(){  
    13.    if(this.state.counter === 2){  
    14.      throw new Error('Crashed');  
    15.    }  
    16.    return(  
    17.      
        
    18.        this.incrementCounter}>Increment Value  
    19.        

      Value of counter: {this.state.counterValue}

        
    20.      
      
  •    )  
  •  }  
  • }  
  • In the above code, you can see that when the counterValue equals 2, it throws an error inside the render method. We know that any error inside the render method leads to unmounting of the component so, to display an error that occurs inside the render method, we use error boundaries. When we are not using the error boundary, we see a blank page instead of seeing an error.

    With error boundaries:

    We have specified earlier that error boundary is a component using one or both of the following methods:

    • static getDerivedStateFromError
    • componentDidCatch

    See the following code where we create an error boundary to handle errors in render phase:

    1. class ErrorBoundary extends React.Component {  
    2.  constructor(props) {  
    3.    super(props);  
    4.    this.state = { hasError: false };  
    5.  }  
    6.  static getDerivedStateFromError(error) {       
    7.    return { hasError: true };   
    8.  }  
    9.   componentDidCatch(error, errorInfo) {         
    10.    logErrorToMyService(error, errorInfo);   
    11.  }  
    12.  render() {  
    13.    if (this.state.hasError) {       
    14.      return 

      Something went wrong

             
    15.    }  
    16.    return this.props.children;  
    17.  }  
    18. }  

    You can see in the above code the getDerivedStateFromError function renders the fallback UI interface when the render method has an error.

    The componentDidCatch logs the error information to an error tracking service.

    Now with error boundary, we can render the CounterComponent in the following way:

    1. <ErrorBoundary>  
    2.   <CounterComponent/>  
    3. ErrorBoundary>  

    67) In which cases do error boundaries not catch errors?

    Following are some cases in which error boundaries don't catch errors:

    • Error boundaries don't catch errors inside the event handlers.
    • During the server-side rendering.
    • In the case when errors are thrown in the error boundary code itself.
    • Asynchronous code using setTimeout or requestAnimationFrame callbacks.

    React Redux Interview Questions

    68) What were the major problems with MVC framework?

    The major problems with the MVC framework are:

    • DOM manipulation was very expensive.
    • It makes the application slow and inefficient.
    • There was a huge memory wastage.
    • It makes the application debugging hard.

    69) Explain the Flux concept.

    Flux is an application architecture that Facebook uses internally for building the client-side web application with React. It is neither a library nor a framework. It is a kind of architecture that complements React as view and follows the concept of Unidirectional Data Flow model. It is useful when the project has dynamic data, and we need to keep the data updated in an effective manner.

    70) What is Redux?

    Redux is an open-source JavaScript library used to manage application state. React uses Redux for building the user interface. The Redux application is easy to test and can run in different environments showing consistent behavior. It was first introduced by Dan Abramov and Andrew Clark in 2015.

    React Redux is the official React binding for Redux. It allows React components to read data from a Redux Store, and dispatch Actions to the Store to update data. Redux helps apps to scale by providing a sensible way to manage state through a unidirectional data flow model. React Redux is conceptually simple. It subscribes to the Redux store, checks to see if the data which your component wants have changed, and re-renders your component.

    For More Information, Click here.


    71) What are the three principles that Redux follows?

    The three principles that redux follows are:

    1. Single source of truth: The State of your entire application is stored in an object/state tree inside a single Store. The single State tree makes it easier to keep changes over time. It also makes it easier to debug or inspect the application.
    2. The State is read-only: There is only one way to change the State is to emit an action, an object describing what happened. This principle ensures that neither the views nor the network callbacks can write directly to the State.
    3. Changes are made with pure functions: To specify how actions transform the state tree, you need to write reducers (pure functions). Pure functions take the previous State and Action as a parameter and return a new State.

    72) List down the components of Redux.

    The components of Redux are given below.

    • STORE: A Store is a place where the entire State of your application lists. It is like a brain responsible for all moving parts in Redux.
    • ACTION: It is an object which describes what happened.
    • REDUCER: It determines how the State will change.

    For More Information, Click here.


    73) Explain the role of Reducer.

    Reducers read the payloads from the actions and then updates the Store via the State accordingly. It is a pure function which returns a new state from the initial State. It returns the previous State as it is if no work needs to be done.


    74) What is the significance of Store in Redux?

    A Store is an object which holds the application's State and provides methods to access the State, dispatch Actions and register listeners via subscribe(listener). The entire State tree of an application is saved in a single Store which makes the Redux simple and predictable. We can pass middleware to the Store which handles the processing of data as well as keep a log of various actions that change the Store's State. All the Actions return a new state via reducers.


    75) How is Redux different from Flux?

    The Redux is different from Flux in the following manner.

    SNReduxFlux
    1.Redux is an open-source JavaScript library used to manage application State.Flux is neither a library nor a framework. It is a kind of architecture that complements React as view and follows the concept of Unidirectional Data Flow model.
    2.Store's State is immutable.Store's State is mutable.
    3.In this, Store and change logic are separate.In this, the Store contains State and change logic.
    4.It has only a single Store.It can have multiple Store.
    5.Redux does not have Dispatcher concept.It has single Dispatcher, and all actions pass through that Dispatcher.

    76) What are the advantages of Redux?

    The main advantages of React Redux are:

    • React Redux is the official UI bindings for react Application. It is kept up-to-date with any API changes to ensure that your React components behave as expected.
    • It encourages good 'React' architecture.
    • It implements many performance optimizations internally, which allows to components re-render only when it actually needs.
    • It makes the code maintenance easy.
    • Redux's code written as functions which are small, pure, and isolated, which makes the code testable and independent.

    77) How to access the Redux store outside a component?

    You need to export the Store from the module where it created with createStore() method. Also, you need to assure that it will not pollute the global window space.

    1. store = createStore(myReducer)  
    2. export default store

LabCorp Interview Questions & Answers:
LabCorp Interview Questions & Answers:
1. What type of people do you not work well with?Be very careful answering this question as most organization employ professionals with an array of personalities and characteristics. You don't want to give the impression that you're going to have problems working with anyone currently employed at the organization. If you through out anything trivial you're going to look like a whiner. Only disloyalty to the organization or lawbreaking should be on your list of personal characteristics of people you can't work with.2. How did you hear about the position At LabCorp?Another seemingly innocuous interview question, this is actually a perfect opportunity to stand out and show your passion for and connection to the company and for job At LabCorp. For example, if you found out about the gig through a friend or professional contact, name drop that person, then share why you were so excited about it. If you discovered the company through an event or article, share that. Even if you found the listing through a random job board, share what, specifically, caught your eye about the role.3. Your client is upset with you for a mistake you made, how do you react?Acknowledge their pain - empathize with them. Then apologize and offer a solution to fix the mistake.4. How well do you know our company?Well, a developed company that is gradually building their reputation in the competitive world.5. Tell me why do you want this job At LabCorp?Bad Answer: No solid answer, answers that don't align with what the job actually offers, or uninspired answers that show your position is just another of the many jobs they're applying for.Good answer: The candidate has clear reasons for wanting the job that show enthusiasm for the work and the position, and knowledge about the company and job.6. Tell me about a problem that you've solved in a unique or unusual way. What was the outcome? Were you happy or satisfied with it?In this question the interviewer is basically looking for a real life example of how you used creativity to solve a problem.7. What can you offer me that another person can't?This is when you talk about your record of getting things done. Go into specifics from your resume and portfolio; show an employer your value and how you'd be an asset.You have to say, “I'm the best person for the job At LabCorp. I know there are other candidates who could fill this position, but my passion for excellence sets me apart from the pack. I am committed to always producing the best results. For example…”8. What education or training have you had that makes you fit for this profession At LabCorp?This would be the first question asked in any interview. Therefore, it is important that you give a proper reply to the question regarding your education. You should have all the documents and certificates pertaining to your education and/or training, although time may not allow the interviewer to review all of them.9. If you were given more initiatives than you could handle, what would you do?First prioritize the important activities that impact the business most. Then discuss the issue of having too many initiatives with the boss so that it can be offloaded. Work harder to get the initiatives done.10. What do you consider to be your greatest achievement so far and why?Be proud of your achievement, discuss the results, and explain why you feel most proud of this one. Was it the extra work? Was it the leadership you exhibited? Was it the impact it had?Download Interview PDF 11. What is your dream job?There is almost no good answer to this question, so don't be specific. If you tell the interviewer that the job you're applying for with his/her company is the perfect job you may loose credibility if you don't sound believable (which you probably won't if you're not telling the truth.) If you give the interviewer some other job the interviewer may get concerned that you'll get dissatisfied with the position if you're hired. Again, don't be specific. A good response could be, “A job where my work ethic and abilities are recognized and I can make a meaningful difference to the organization.”12. Are you currently looking at other job opportunities?Just answer this question honestly. Sometime an employer wants to know if there are other companies you're considering so that they can determine how serious you are about the industry, they're company and find out if you're in demand. Don't spend a lot of time on this question; just try to stay focused on the job you're interviewing for.13. Why do you want this job At LabCorp?This question typically follows on from the previous one. Here is where your research will come in handy. You may want to say that you want to work for a company that is Global Guideline, (market leader, innovator, provides a vital service, whatever it may be). Put some thought into this beforehand, be specific, and link the company's values and mission statement to your own goals and career plans.14. What did you dislike about your old job?Try to avoid any pin point , like never say “I did not like my manager or I did not like environment or I did not like team” Never use negative terminology. Try to keep focus on every thing was good At LabCorp , I just wanted to make change for proper growth.15. If you were hiring a person for this job At LabCorp, what would you look for?Discuss qualities you possess required to successfully complete the job duties.16. If the company you worked for was doing something unethical or illegal, what would you do?Report it to the leaders within the company. True leaders understand business ethics are important to the company's longevity17. Tell me a difficult situation you have overcome in the workplace?Conflict resolution, problem solving, communication and coping under pressure are transferable skills desired by many employers At LabCorp.Answering this question right can help you demonstrate all of these traits.☛ Use real-life examples from your previous roles that you are comfortable explaining☛ Choose an example that demonstrates the role you played in resolving the situation clearly☛ Remain professional at all times – you need to demonstrate that you can keep a cool head and know how to communicate with people18. Tell us something about yourself?Bad Answer: Candidates who ramble on about themselves without regard for information that will actually help the interviewer make a decision, or candidates who actually provide information showing they are unfit for the job.Good answer: An answer that gives the interviewer a glimpse of the candidate's personality, without veering away from providing information that relates to the job. Answers should be positive, and not generic.19. How do you handle confidentiality in your work?Often, interviewers will ask questions to find out the level of technical knowledge At LabCorp that a candidate has concerning the duties of a care assistant. In a question such as this, there is an opportunity to demonstrate professional knowledge and awareness. The confidentiality of a person's medical records is an important factor for a care assistant to bear in mind.20. What are you looking for in a new position At LabCorp?I've been honing my skills At LabCorp for a few years now and, first and foremost, I'm looking for a position where I can continue to exercise those skills. Ideally the same things that this position has to offer. Be specific.21. What motivates you at the work place?Keep your answer simple, direct and positive. Some good answers may be the ability to achieve, recognition or challenging assignments.22. Can you describe your ideal boss/supervisor?During the interview At LabCorp process employers will want to find out how you respond to supervision. They want to know whether you have any problems with authority, If you can work well as part of a group (see previous question) and if you take instructions well etc.Never ever ever, criticize a past supervisor or boss. This is a red flag for airlines and your prospective employer will likely assume you are a difficult employee, unable to work in a team or take intruction and side with your former employer.23. Why are you leaving last job?Although this would seem like a simple question, it can easily become tricky. You shouldn't mention salary being a factor at this point At LabCorp. If you're currently employed, your response can focus on developing and expanding your career and even yourself. If you're current employer is downsizing, remain positive and brief. If your employer fired you, prepare a solid reason. Under no circumstance should you discuss any drama or negativity, always remain positive.24. What motivates you?I've always been motivated by the challenge – in my last role, I was responsible for training our new recruits and having a 100% success rate in passing scores. I know that this job is very fast-paced and I'm more than up for the challenge. In fact, I thrive on it.25. Tell me about a time when you had to use your presentation skills to influence someone's opinion At LabCorp?Example stories could be a class project, an internal meeting presentation, or a customer facing presentation.Download Interview PDF 26. How do you handle conflicts with people you supervise?At first place, you try to avoid conflicts if you can. But once it happens and there's no way to avoid it, you try to understand the point of view of the other person and find the solution good for everyone. But you always keep the authority of your position.27. Why should I hire you At LabCorp?To close the deal on a job offer, you MUST be prepared with a concise summary of the top reasons to choose you. Even if your interviewer doesn't ask one of these question in so many words, you should have an answer prepared and be looking for ways to communicate your top reasons throughout the interview process.28. How have you shown yourself to be a leader?Think about a time where you've rallied a group of people around a cause / idea / initiative and successfully implemented it. It could be a small or large project but the key is you want to demonstrate how you were able to lead others to work for a common cause.29. How do you deal with conflict in the workplace At LabCorp?When people work together, conflict is often unavoidable because of differences in work goals and personal styles. Follow these guidelines for handling conflict in the workplace.☛ 1. Talk with the other person.☛ 2. Focus on behavior and events, not on personalities.☛ 3. Listen carefully.☛ 4. Identify points of agreement and disagreement.☛ 5. Prioritize the areas of conflict.☛ 6. Develop a plan to work on each conflict.☛ 7. Follow through on your plan.☛ 8. Build on your success.30. What have you done to reduce costs, increase revenue, or save time?Even if your only experience is an internship, you have likely created or streamlined a process that has contributed to the earning potential or efficiency of the practice. Choose at least one suitable example and explain how you got the idea, how you implemented the plan, and the benefits to the practice.31. How do you feel about giving back to the community?Describe your charitable activities to showcase that community work is important to you. If you haven't done one yet, go to www.globalguideline.com - charitable work is a great way to learn about other people and it's an important part of society - GET INVOLVED!32. What can you tell me about team work as part of the job At LabCorp?There is usually a team of staff nurses working in cooperation with each other. A team of nurses has to get along well and coordinate their actions, usually by dividing their responsibilities into sectors or specific activities. They help each other perform tasks requiring more than one person.33. What is your perception of taking on risk?You answer depends on the type of company you're interviewing for. If it's a start up, you need to be much more open to taking on risk. If it's a more established company, calculated risks to increase / improve the business or minimal risks would typically be more in line.34. How would your former employer describe you?In all likelihood, the interviewer will actually speak with your former employer so honesty is key. Answer as confidently and positively as possible and list all of the positive things your past employer would recognize about you. Do not make the mistake of simply saying you are responsible, organized, and dependable. Instead, include traits that are directly related to your work as a medical assistant, such as the ability to handle stressful situations and difficult patients, the way you kept meticulous records, and more.35. Describe your academic achievements?Think of a time where you really stood out and shined within college. It could be a leadership role in a project, it could be your great grades that demonstrate your intelligence and discipline, it could be the fact that you double majored. Where have you shined?36. What do you consider to be your weaknesses?What your interviewer is really trying to do with this question-beyond identifying any major red flags-is to gauge your self-awareness and honesty. So, “I can't meet a deadline to save my life At LabCorp” is not an option-but neither is “Nothing! I'm perfect!” Strike a balance by thinking of something that you struggle with but that you're working to improve. For example, maybe you've never been strong at public speaking, but you've recently volunteered to run meetings to help you be more comfortable when addressing a crowd.37. What do you feel you deserve to be paid?Do your research before answering this question - first, consider what the market average is for this job. You can find that by searching on Google (title followed by salary) and globalguideline.com and other websites. Then, consider this - based on your work experience and previous results, are you above average, if yes, by what % increase from your pay today from your perspective? Also - make sure if you aim high you can back it up with facts and your previous results so that you can make a strong case.38. Did you get on well with your last manager?A dreaded question for many! When answering this question never give a negative answer. “I did not get on with my manager” or “The management did not run the business well” will show you in a negative light and reduce your chance of a job offer. Answer the question positively, emphasizing that you have been looking for a career progression. Start by telling the interviewer what you gained from your last job At LabCorp39. Do you have the ability to articulate a vision and to get others involved to carry it out?If yes, then share an example of how you've done so at work or college. If not, then discuss how you would do so. Example: "I would first understand the goals of the staff members and then I would align those to the goals of the project / company. Then I would articulate the vision of that alignment and ask them to participate. From there, we would delegate tasks among the team and then follow up on a date and time to ensure follow through on the tasks. Lastly, we would review the results together."40. What differentiates this company from other competitors?Be positive and nice about their competitors but also discuss how they are better than them and why they are the best choice for the customer. For example: "Company XYZ has a good product, but I truly believe your company has a 3-5 year vision for your customer that aligns to their business needs."Download Interview PDF 41. Tell me an occasion when you needed to persuade someone to do something?Interpersonal relationships are a very important part of being a successful care assistant. This question is seeking a solid example of how you have used powers of persuasion to achieve a positive outcome in a professional task or situation. The answer should include specific details.42. What is your greatest strength? How does it help you At LabCorp?One of my greatest strengths, and that I am a diligent worker... I care about the work getting done.. I am always willing to help others in the team.. Being patient helps me not jump to conclusions... Patience helps me stay calm when I have to work under pressure.. Being a diligent worker.. It ensures that the team has the same goals in accomplishing certain things.43. Explain me about a challenge or conflict you've faced at work At LabCorp, and how you dealt with it?In asking this interview question, your interviewer wants to get a sense of how you will respond to conflict. Anyone can seem nice and pleasant in a job interview, but what will happen if you're hired?. Again, you'll want to use the S-T-A-R method, being sure to focus on how you handled the situation professionally and productively, and ideally closing with a happy ending, like how you came to a resolution or compromise.44. Why are you interested in this type of job At LabCorp?You're looking for someone who enjoys working with the elderly, or a caring, sociable, and nurturing person.45. What is the most important lesson / skill you've learned from school?Think of lessons learned in extra curricular activities, in clubs, in classes that had a profound impact on your personal development. For example, I had to lead a team of 5 people on a school project and learned to get people with drastically different personalities to work together as a team to achieve our objective.46. What is it about this position At LabCorp that attracts you the most?Use your knowledge of the job description to demonstrate how you are a suitable match for the role.47. How important is a positive attitude to you?Incredibly important. I believe a positive attitude is the foundation of being successful - it's contagious in the workplace, with our customers, and ultimately it's the difference maker.48. Why should we select you not others?Here you need to give strong reasons to your interviewer to select you not others. Sell yourself to your interviewer in interview in every possible best way. You may say like I think I am really qualified for the position. I am a hard worker and a fast learner, and though I may not have all of the qualifications that you need, I know I can learn the job and do it well.”49. If you were an animal, which one would you want to be?Seemingly random personality-test type questions like these come up in interviews generally because hiring managers want to see how you can think on your feet. There's no wrong answer here, but you'll immediately gain bonus points if your answer helps you share your strengths or personality or connect with the hiring manager. Pro tip: Come up with a stalling tactic to buy yourself some thinking time, such as saying, “Now, that is a great question. I think I would have to say… ”50. What is your biggest regret to date and why?Describe honestly the regretful action / situation you were in but then discuss how you proactively fixed / improved it and how that helped you to improve as a person/worker.51. Describe to me the position At LabCorp you're applying for?This is a “homework” question, too, but it also gives some clues as to the perspective the person brings to the table. The best preparation you can do is to read the job description and repeat it to yourself in your own words so that you can do this smoothly at the interview.52. What was the most important task you ever had?There are two common answers to this question that do little to impress recruiters:☛ ‘I got a 2.1'☛ ‘I passed my driving test'No matter how proud you are of these achievements, they don't say anything exciting about you. When you're going for a graduate job, having a degree is hardly going to make you stand out from the crowd and neither is having a driving licence, which is a requirement of many jobs.53. How would you observe the level of motivation of your subordinates?Choosing the right metrics and comparing productivity of everyone on daily basis is a good answer, doesn't matter in which company you apply for a supervisory role.54. Do you have good computer skills?It is becoming increasingly important for medical assistants to be knowledgeable about computers. If you are a long-time computer user with experience with different software applications, mention it. It is also a good idea to mention any other computer skills you have, such as a high typing rate, website creation, and more.55. Where do you see yourself professionally five years from now At LabCorp?Demonstrate both loyalty and ambition in the answer to this question. After sharing your personal ambition, it may be a good time to ask the interviewer if your ambitions match those of the company.Download Interview PDF 56. Give me an example of an emergency situation that you faced. How did you handle it?There was a time when one of my employers faced the quitting of a manager in another country. I was asked to go fill in for him while they found a replacement and stay to train that person. I would be at least 30 days. I quickly accepted because I knew that my department couldn't function without me.57. How have you changed in the last five years?All in a nutshell. But I think I've attained a level of personal comfort in many ways and although I will change even more in the next 5-6 years I'm content with the past 6 and what has come of them.58. Explain an idea that you have had and have then implemented in practice?Often an interview guide will outline the so-called ‘STAR' approach for answering such questions; Structure the answer as a situation, task, action, and result: what the context was, what you needed to achieve, what you did, and what the outcome was as a result of your actions.59. Why should the we hire you as this position At LabCorp?This is the part where you link your skills, experience, education and your personality to the job itself. This is why you need to be utterly familiar with the job description as well as the company culture. Remember though, it's best to back them up with actual examples of say, how you are a good team player.60. What is your desired salary At LabCorp?Bad Answer: Candidates who are unable to answer the question, or give an answer that is far above market. Shows that they have not done research on the market rate, or have unreasonable expectations.Good answer: A number or range that falls within the market rate and matches their level of mastery of skills required to do the job.61. Why do you want to work At LabCorp for this organisation?Being unfamiliar with the organisation will spoil your chances with 75% of interviewers, according to one survey, so take this chance to show you have done your preparation and know the company inside and out. You will now have the chance to demonstrate that you've done your research, so reply mentioning all the positive things you have found out about the organisation and its sector etc. This means you'll have an enjoyable work environment and stability of employment etc – everything that brings out the best in you.62. Explain me about your experience working in this field At LabCorp?I am dedicated, hardworking and great team player for the common goal of the company I work with. I am fast learner and quickly adopt to fast pace and dynamic area. I am well organized, detail oriented and punctual person.63. What would your first 30, 60, or 90 days look like in this role At LabCorp?Start by explaining what you'd need to do to get ramped up. What information would you need? What parts of the company would you need to familiarize yourself with? What other employees would you want to sit down with? Next, choose a couple of areas where you think you can make meaningful contributions right away. (e.g., “I think a great starter project would be diving into your email marketing campaigns and setting up a tracking system for them.”) Sure, if you get the job, you (or your new employer) might decide there's a better starting place, but having an answer prepared will show the interviewer where you can add immediate impact-and that you're excited to get started.64. What do you think is your greatest weakness?Don't say anything that could eliminate you from consideration for the job. For instance, "I'm slow in adapting to change" is not a wise answer, since change is par for the course in most work environments. Avoid calling attention to any weakness that's one of the critical qualities the hiring manager is looking for. And don't try the old "I'm a workaholic," or "I'm a perfectionist.65. Tell me something about your family background?First, always feel proud while discussing about your family background. Just simple share the details with the things that how they influenced you to work in an airline field.66. Are you planning to continue your studies and training At LabCorp?If asked about plans for continued education, companies typically look for applicants to tie independent goals with the aims of the employer. Interviewers consistently want to see motivation to learn and improve. Continuing education shows such desires, especially when potentials display interests in academia potentially benefiting the company.Answering in terms of “I plan on continuing my studies in the technology field,” when offered a question from a technology firm makes sense. Tailor answers about continued studies specific to desired job fields. Show interest in the industry and a desire to work long-term in said industry. Keep answers short and to the point, avoiding diatribes causing candidates to appear insincere.67. Describe a typical work week for this position At LabCorp?Interviewers expect a candidate for employment to discuss what they do while they are working in detail. Before you answer, consider the position At LabCorp you are applying for and how your current or past positions relate to it. The more you can connect your past experience with the job opening, the more successful you will be at answering the questions.68. What type of work environment do you prefer?Ideally one that's similar to the environment of the company you're applying to. Be specific.69. How would you rate your communication and interpersonal skills for this job At LabCorp?These are important for support workers. But they differ from the communication skills of a CEO or a desktop support technician. Communication must be adapted to the special ways and needs of the clients. Workers must be able to not only understand and help their clients, but must project empathy and be a warm, humane presence in their lives.70. Do you have any questions for me?Good interview questions to ask interviewers at the end of the job interview include questions on the company growth or expansion, questions on personal development and training and questions on company values, staff retention and company achievements.Download Interview PDF 71. How would you motivate your team members to produce the best possible results?Trying to create competitive atmosphere, trying to motivate the team as a whole, organizing team building activities, building good relationships amongst people.72. How do you act when you encounter competition?This question is designed to see if you can rise the occasion. You want to discuss how you are the type to battle competition strongly and then you need to cite an example if possible of your past work experience where you were able to do so.73. What would you like to have accomplished by the end of your career?Think of 3 major achievements that you'd like to accomplish in your job when all is said and done - and think BIG. You want to show you expect to be a major contributor at the company. It could be creating a revolutionary new product, it could be implementing a new effective way of marketing, etc.74. What do you think we could do better or differently?This is a common one at startups. Hiring managers want to know that you not only have some background on the company, but that you're able to think critically about it and come to the table with new ideas. So, come with new ideas! What new features would you love to see? How could the company increase conversions? How could customer service be improved? You don't need to have the company's four-year strategy figured out, but do share your thoughts, and more importantly, show how your interests and expertise would lend themselves to the job.75. What features of your previous jobs have you disliked?It's easy to talk about what you liked about your job in an interview, but you need to be careful when responding to questions about the downsides of your last position. When you're asked at a job interview about what you didn't like about your previous job, try not to be too negative. You don't want the interviewer to think that you'll speak negatively about this job or the company should you eventually decide to move on after they have hired you.76. How would your friends describe you?My friends would probably say that I'm extremely persistent – I've never been afraid to keep going back until I get what I want. When I worked as a program developer, recruiting keynote speakers for a major tech conference, I got one rejection after another – this was just the nature of the job. But I really wanted the big players – so I wouldn't take no for an answer. I kept going back to them every time there was a new company on board, or some new value proposition. Eventually, many of them actually said "yes" – the program turned out to be so great that we doubled our attendees from the year before. A lot of people might have given up after the first rejection, but it's just not in my nature. If I know something is possible, I have to keep trying until I get it.77. Do you think you have enough experience At LabCorp?If you do not have the experience they need, you need to show the employer that you have the skills, qualities and knowledge that will make you equal to people with experience but not necessary the skills. It is also good to add how quick you can pick up the routine of a new job role.

HOW TO RESPOND TO BEHAVIORAL INTERVIEW QUESTIONS?
HOW TO RESPOND TO BEHAVIORAL INTERVIEW QUESTIONS?
A large part of what makes job interviews nerve-wracking is that you don’t know what you’re going to be asked. While you can’t know the exact question list before an interview, there are some common types of questions that interviewers often ask that you can prepare to answer, and one of these is behavioral interview questions.We’ll cover how to answer behavioral interview questions and give you some example questions and answers as well as explain what behavioral interview questions are and why interviewers ask them.HOW TO ANSWER BEHAVIORAL JOB INTERVIEW QUESTIONSLike with all interview questions, there is a right and a wrong answer — the issue with behavioral questions is that this answer can be much more difficult to figure out than with traditional interviews.While it is, as we said before, more difficult to game behavioral interview questions than traditional ones, there is still a chance that you can figure out how to answer a question correctly based on the way it’s asked.The interviewer isn’t trying to trick good people into giving “bad answers” — but they are trying to trick people with poor judgment into revealing themselves early on.In this vein, here are some big things to keep in mind if you find yourself in a behavioral job interview:Highlight your skills. Think about the sort of skills you need to demonstrate in order to be successful at the job you hope to do. These skills are typically more general than they are specific — things like leadership skills, the ability to work with a team, brilliant decision-making, the advanced use of an industry technique etc.When you’re constructing your answer, think about how to portray your actions in such a way that shows off those skills.Tell a story. Remember that you’re telling a story and that ultimately, how you tell that story matters most of all. Try to make your story flow as naturally as possible — don’t overload the interviewer with unnecessary details, or alternately, forget too many details for the story to make sense.They need to understand your answer in order to parse out your behavior. They can’t do that if they can’t understand the story you just told them — in addition to which, they might just find that a person who can’t tell a simple story is just too annoying to work with.Use the STAR method. If you’re really having trouble telling your story, remember that good old STAR method:Situation. Start by giving context. Briefly explain the time, place, and relevant characters in your story.Task. Next, tell the interviewer your role in the story, whether it was a task assigned to you or some initiative you took on your own.Action. Now comes the juicy stuff; let the hiring manager know what actions you took in response to the situation and your task. Interviewers are interested in how and why you did something just as much as what you did, so spell out your thought process when possible.This is where you showcase your skills, so try to think of actions that align well with the job you’re applying for.Result. Finally, explain the end result of your actions. Your focus should always be on what value you contributed to the company, not bragging about your personal accomplishments.Note that while the result should always be positive, some behavioral interview questions specifically ask about negative situations. In these cases, finish by discussing what you learned from the experience or how the project could have been improved.EXAMPLE BEHAVIORAL INTERVIEW QUESTIONS AND ANSWERSEssentially, a behavioral interview means being asked a bunch of open-ended questions which all have the built-in expectation that your answer will be in the form of a story.These questions are difficult to answer correctly specifically because the so-called “correct” answers are much more likely to vary compared to traditional interview questions, whose correct answers are typically more obvious and are often implied.Behavioral interviewers are likely to ask more follow-up questions than normal, while giving less of themselves away. They want to hear you talk and react to every opportunity they give you, because the more you talk, the more you reveal about yourself and your work habits.And that’s okay. The takeaway here shouldn’t be that “the hiring manager wants to trick me into talking, so I should say as little as possible.”The real trick with this kind of question is to use the opportunities you’re given to speak very carefully — don’t waste time on details that make you look bad, for example, unless those details are necessary to show how you later improved.In addition to these general techniques interviewers might use on you, here are some common questions you might be asked during a behavioral interview:Q: Tell me about a time when you had to take a leadership role on a team project.A: As a consultant at XYZ Inc., I worked with both the product and marketing teams. When the head of the marketing team suddenly quit, I was asked to step up and manage that deparment while they looked for her replacement. We were in the midst of a big social media campaign, so I quickly called toghether the marketing team and was updated on the specifics of the project.By delegating appropriately and taking over the high-level communications with affiliates, we were able to get the project out on time and under budget. After that, my boss stopped looking for a replacement and asked if I’d like to head the marketing team full time.Q: Can you share an example of a time when you disagreed with a superior?A: In my last role at ABC Corp., my manager wanted to cut costs by outsourcing some of our projects to remote contractors. I understood that it saved money, but some of those projects were client-facing, and we hadn’t developed a robust vetting process to make sure that the contractors’ work was consistent and high-quality. I brought my concerns to him, and he understood why I was worried.He explained that cost-cutting was still important, but was willing to compromise by keeping some important projects in-house. Additionally, he accepted my suggestion of using a system of checks to ensure quality and rapidly remove contractors who weren’t performing as well. Ultimately, costs were cut by over 15% and the quality of those projects didn’t suffer as a result.Q: Tell me about a time when you had to work under pressure.A: My job as lead editor for The Daily Scratch was always fast-paced, but when we upgraded our software and printing hardware nearly simultaneously, the pressure got turned up to 11. I was assigned with training staff on the new software in addition to my normal responsibilities. When we were unable to print over a long weekend while the new printing hardware was being set up, I wrote and recorded a full tutorial that answered the most frequently asked questions I’d been receiving over the previous week.With a staff of 20 writers, this really cut down on the need for one-on-one conversations and tutorials. While management was worried we wouldn’t be able to have the writers working at full capacity the following week, the tutorial was so effective that everyone got right on track without skipping a beat.Q: Can you describe a time when you had to motivate an employee?A: When I was the sales manager at Nice Company, we had a big hiring push that added six sales reps to my team in a matter of weeks. One worker in that bunch was working a sales job for the first time ever, and she had an aversion to cold calls. While her email correspondence had fantastic results, her overall numbers were suffering because she was neglecting her call targets.I sat down with her and explained that she should try to incorporate her winning writing skills into her cold calls. I suggested following her normal process for writing an email to cold calls; research the company and target and craft a message that suits them perfectly. She jumped at the idea and starting writing scripts that day. Within a couple of weeks, she was confidently making cold calls and had above-average numbers across the board.Q: Tell me about a time you made a mistake at work.A: When I landed my first internship, I was eager to stand out by going the extra mile. I was a little too ambitious, though — I took on too many assignments and offered help to too many coworkers to possibly juggle everything. When I was late with at least one task every week, my coworkers were understandably upset with me.After that experience, I created a tracking system that took into account how long each task would realistically take. This method really helped me never make promises I couldn’t keep. After that first month, I never handed in an assignment late again.MORE BEHAVIORAL INTERVIEW QUESTIONSWhat have you done in the past to prevent a situation from becoming too stressful for you or your colleagues to handle?Tell me about a situation in which you have had to adjust to changes over which you had no control. How did you handle it?What steps do you follow to study a problem before making a decision? Why?When have you had to deal with an irate customer? What did you do? How did the situation end up?Have you ever had to “sell” an idea to your co-workers? How did you do it?When have you brought an innovative idea into your team? How was it received?Tell me about a time when you had to make a decision without all the information you needed. How did you handle it?Tell me about a professional goal that you set that you did not reach. How did it make you feel?Give an example of when you had to work with someone who was difficult to get along with. How/why was this person difficult? How did you handle it? How did the relationship progress?Tell me about a project that you planned. How did your organize and schedule the tasks? Tell me about your action plan.WHAT ARE BEHAVIORAL INTERVIEW QUESTIONS?Behavioral interview questions are questions about how you’ve dealt with work situations in the past and seek to understand your character, motivations, and skills. The idea behind behavioral interview questions is that you’ll reveal how you’ll behave in the future based on your actions in the past.Unlike traditional interview questions, a hiring manager or recruiter is looking for concrete examples of various situations you’ve been in at work. As such, the best way to prepare for any and all behavioral interview questions is to have an expansive set of stories ready for your interview.A hiring manager is never going to come right out and tell you — before, during, or after the fact — whether or not your interview with them is traditional or behavioral.That’s because the difference between the two is more related to philosophy than it is necessarily technique.Often, an employer won’t even know themselves that the interview they’re conducting is behavioral rather than traditional — the deciding factors are the questions that they decide to ask, and where the interview’s focus settles on.In a nutshell, traditional interviews are focused on the future, while behavioral interviews are focused on the past.In a traditional interview, you’re asked a series of questions where you’re expected to talk about yourself and your personal qualities.Interviews in this vein tend to ask questions that are sort of psychological traps — oftentimes the facts of your answer matter less than the way you refer to and frame those facts.Moreover, if you find that you’re able to understand the underlying thing an interviewer is trying to learn about you by asking you a certain question, you might even find you’re able to game the system of the traditional interview a little bit by framing your answer in a particular way.Behavioral interviews are harder to game, because instead of asking about how you might deal with a particular situation, they focus on situations you’ve already encountered.In a behavioral interview, you probably won’t find yourself being asked about your strengths. Instead, you’ll be asked about specific problems you encountered, and you’ll have to give detailed answers about how you dealt with that problem, your thought process for coming up with your solution, and the results of implementing that solution
