It may be Parameterized or Default. If the user does not define a constructor within a class, the default constructor is always included in that code.The objective of Constructor is to initialize an object called object initialization. Constructors are mainly created for initializing an object.2) How Java enable High Performance?Java uses a Just-In-Time Compiler to enable high performance. Just-In-Time Compiler is a program that turns Java bytecode, which is a program that contains an instruction that must be interpreted into instruction that can be sent directly to the processor.3) Why is java considered as dynamic?It is designed to change the evolving environment. Java can carry an extensive amount of runtime information that can be used to verify and resolve access to the object at runtime.4) What is joins in SQL?Joins is nothing but connecting two or more table to fetch the record from two or more databases.5) Can we have Private Constructor in Java?Private Constructor is used if you do not want other class to instantiate the object. Private Constructor is used in Singleton design Pattern, Factory Method Design Pattern.6) Differentiate Between Primary Key and Unique Key.Primary KeyUnique Key1. In a Primary key, there should be only one primary key in a table.1. In A Unique key, there can be more than one unique key in a table.2. Primary key will block duplicate value and a null value.2. Unique key will block duplicate value and accept a null value.7) Differentiate between Method Overloading and Method Overriding.Method OverloadingMethod Overriding1. Method Overloading is used to gain the readability of the program.1. Method Overriding is used to provide the specific implementation of the method that already provided by the superclass.2. In the case of Method Overloading, the parameter must be different.2. In the case of Method Overriding, the parameter must be equal.3. Overloading happens at Compile time.3. Overriding happens at runtime.4. The Return type of method does not matter in case of method overloading it can be the same or different.4. In the case of method Overriding, the return type must be the same.5. you can overload a static, final and private method in Java5. You cannot override a static, final and private method in Java.8) What is the purpose of finalize () method in Java?Finalize () method in java is a special method much like the main method in java. Finalize () method is called before garbage collector reclaims the object, its last chance for any object to perform clean up activity i.e. releasing any fixed order resources held, terminating connection if open etc.9) Why can static method not override?A static method cannot override because the static method is bound with class whereas instance method is bound with an object. Static method belongs to the class area and Instance method belong to the heap area.10) What is singleton Class?Singleton Class limited the number to one but allowing the flexibility to create more object if the situation changes.11) Can we override java main method?No, because main is a Static Method.12) What is Class Cast Exception?Class Cast Exception is thrown by java when you try to cast an object of one data type to another data type. Java allows us to cast the variable of one type to another as long as the casting happens between compatible data type.13) Why polymorphism is used in Java?The good reason for why polymorphism is a need in Java because the concept is extensively used in implementing inheritance. It plays an important role in allowing the object having a different internal structure to share the same external interface.14) What is an Abstract class?An Abstract class is one that is not used to create an object. It is only used as base class for the other class. The Abstract class is always public or friendly.Syntax:public abstract class class_name { //class member } 15) Can I have Private Constructor in Abstract Class?Abstract Class can have Private Constructor But that class cannot be extended by another class. Alternatively, of adding a static inner class inside the Abstract Class and extends that Abstract Class.HCL HR Interview Questions1) Tell us about yourself.This is the most common questions asked for both fresher's as well as experienced candidates.

Some of the coding questions are given below for practice.1) Write code to reverse the linked list?#include #include struct Node { int data; struct Node* next; }; /* Function for reversing the linked list */ static void reverseList(struct Node** head_ref) { struct Node* t2 = NULL; struct Node* start = *head_ref; struct Node* t1 = NULL; while (start != NULL) { t1 = start->next; start->next = t2; t2 = start; start = t1; } *head_ref = t2; } void newNode(struct Node** head_ref, int new_data) { struct Node* new_node = (struct Node*) malloc(sizeof(struct Node)); new_node->data = new_data; new_node->next = (*head_ref); (*head_ref) = new_node; } /* Function to print linked list */ void printList(struct Node *head) { struct Node *temp = head; while(temp != NULL) { printf("%d ", temp->data); temp = temp->next; } } int main() { struct Node* head = NULL; newNode(&head, 20); newNode(&head, 14); newNode(&head, 30); newNode(&head, 68); printf("Input linked list\n"); printList(head); reverseList(&head); printf("\nReversed Linked list \n"); printList(head); } Output:Input linked list 68 30 14 20 Reversed Linked list 20 14 30 68 2) Write a code which multiplies two numbers using the minimum number of additions.#include int main() { int product=0, x, y, n; x=10; y= 20; for(n = 0; n Before swap 20 30 After swap 30 20 4) Write a program to calculate the nth term of the Fibonacci series?#include int fun(int n) { if (n >1; } total_bits=count_onebit+count_zerobit; printf("Total bits are=%d Total zero bits are=%d Total one's bits are= %d", total_bits, count_zerobit, count_onebit); } Output:Total bits are=4 Total zero bits are=0 Total one's bits are= 4 6) Write an algorithm to compute the output for X^N, having complexity log n.#include int pow(int x, int n) { int y; if( n == 0) return 1; y = pow(x, n/2); if (n%2 == 0) return y*y; else return x*y*y; } int main() { int x = 6; int n = 3; printf("The output for x^n, where x=%d, n=%d, %d", x, n, pow(x, n)); return 0; } Output:The output for x^n, where x=6, n=3, 216 7) Write code to check a binary tree is BST tree or not?public class CheckBST { public static Node prevNode = null; //Method1: public boolean isBST1(Node root) { if (root != null) { if (!isBST1(root.left)) return false; if (prevNode != null && prevNode.data >= root.data) { return false; } prevNode = root; return isBST1(root.right); } return true; } //method 2 public boolean isBST2(Node root, int min, int max) { if (root != null) { if (root.data > max || root.data 10 Andhra Pradesh 2) Why we use sprint() function?sprint() is a C library function which is termed as "string print." sprintf function is used to hold the formatted data output as String.Syntax:int sprintf (char *string, const char *form, .... ) Example:#include int main() { char string[50]; int a = 10, b = 5, c; c = a * b; sprintf(string, "multiplication of %d and %d is %d", a, b, c); printf("%s", string); return 0; } Output:multiplication of 10 and 5 is 2 3) How to differentiate between char a[]= ?String and char*a =?String.The statements:Char a[ ]= "computer";char *a= "computer";The difference between the above two statements is that the first statement will create an array of 9 elements will automatically add the null pointer and the size of array 'a' will be 9.But the second statement will create a pointer variable. We cannot perform any array operation on this pointer variable as it will be stored in read-only mode.Example:#include int main() { char a[] = "Computer"; printf("%lu", sizeof(a)); a[1] = 'n'; printf("\n%s", a); return 0; } Output:9 Cnmputer Example 2#include int main() { char *a = "Computer"; printf("%lu", sizeof(a)); return 0; } 4) Explain Data breakpoints? Where can we use this?Data Breakpoint is a strong feature available for C++, which allow us to stop the execution when the value stored at a particular memory location changes. Data breakpoints can be used to solve the memory corruption issue.5) Differentiate between new and malloc()?The new and malloc() both are used for dynamic memory allocation. But there are various differences between new and malloc, which are given below,new is an operator in C language, whereas malloc() is a function for memory allocation.new operator calls the constructor, whereas malloc() does not call the constructor.The memory allocated from the "free store" by new operator, whereas memory allocated from the heap by malloc() function.On failure of execution, new operator throws an exception, whereas malloc() returns Null.new operator does not require the sizeof() operator, malloc() function requires the sizeof() operator to know the memory size.6) Differentiate between process and thread?Following are the basic differences between the process and the thread:The Process is an execution of a program, whereas thread is a lightweight process.A Process does not share the resources like memory, whereas thread can share the resources.The Process takes more time for context switching, whereas thread requires less time for context switching.The Process is less efficient as compared to a thread in terms of communication.7) What is C++ Shorthand property? What is its role?C++ provides shorthand property, which enables a programmer to use the assignment operator in a shorter way.Example:x=x+5; can be written as x+=5 using shorthandx=x-10; can be written as x-=10;8) What do you understand by function prototype declaration and definition?Function prototype declaration: function prototype declaration statement gives the following information about the function:It tells the symbolic name of the functions.Information about the return type of function.Information about the argument passed as input with their datatypes.Example:int add(int a, int b, int c) Where add is the name of a function, and a, b and c are the passed arguments.Function definition: The function definition is the actual source code of the function. Function definition gives information that what that function actually does.Example:int add(int a, int b, int c){ c= a + b; return c; } 9) What do you understand by Conditional Operators?Conditional operators are ternary operators with three operands, which are used as shorthand in place of the if-else statement.Conditional operators return the first expression if the condition is true and return second expression if the condition is false.Syntax:(Check expression)? Expression1: Expression2; Example:var = (x The primary protocols used at this level are:IP (internet protocol): This protocol is responsible for forwarding the packets from source host to destination using an address which is consisted by packet header. IP has two main versions IPv4 and IPv6.ICMP (Internet control message protocol): This protocol is mainly responsible for informing the problem in the network.ARP (Address resolution protocol): ARP protocol is an essential protocol of the TCP/IP model, and it is responsible to resolve an IPv4 address to physical address.3. Transport Layer: This is the third layer of the TCP/IP model, which is responsible for the communication between the source host and destination host and error-free data transmission.This layer consists of mainly two protocols:TCP (Transmission Control Protocol): TCP is a reliable protocol for error-free communication between the source and destination host. It's a connection-oriented protocol.UDP (User Datagram Protocol): This protocol is not reliable as compare to TCP protocol, we can use this protocol which does not require reliable communication. It is a connectionless protocol.4. Application layer: This is the top layer of the TCP/IP model. It describes the application protocol and provides node-to-node communication.This layer contains various higher level protocols which are:HTTP and HTTPs(Hypertext transfer protocol)FTP(File transfer protocol)SSH( Secure Shell)TFTP(Trivial file transfer protocol)SMTP(Simple mail transfer protocol)DHCP(Dynamic host configuration protocol)2) Explain the working of the stack while calling a function? When stack overflow occurred?The Stack is a particular area of RAM, just like as Heap. But stack is used to store local variables, parameters and return values used inside a function and stack stores and deallocates memory automatically.When we call a function, stack performs following steps:Push space for the return variables.Push parameters in the stack.Push the local variable of the function.When we call a function, stack adds a stack frame which consists space for actual parameters, local variables, return address, etc. This stack frame lives in active frame till the time function is being called, and once execution finishes then stack remove that stack frame from the stack.Stack Overflow: As we know that stack deallocated the memory and free up space after execution but still there is a condition when complete stack space used, and there is no more space to save the variables, so this is called stack overflow. It occurs because the space size of the stack is also limited in size, and at the time of execution if we allocate more memory than available memory than overflow occurred and the program got crashed. Some example for stack overflow are:Use of Infinite recursionUse of very large stack variableUse of very deep recursion3) Explain the meaning for the declaration: int*const p & const int* const p?int * const p: By declaring a pointer in such a way that means we are declaring point variable p as constant, which cannot be changed. We cannot change the address its holding, or it cannot point to other variables. If we try to change the address of p, then it will give a compile time error.const int * const p: By declaring a pointer in such a way means, we cannot change the address of the pointer as we as we cannot change the address at that address. If we try to do it, then it will generate a compile time error.4) What are default functions in C++C++ provides the six default member functions which are given below:Default constructorDestructorsCopy constructorsCopy assignment operatorsMove constructorsMove assignment operators5) Which data structure is used for the dictionary?To implement a dictionary, which type of data structure should be used depends on what we required, there are some following data structure which can be used for implementation of the dictionary.Hash-table: If we want a simple dictionary with no option for the prefix, or nearest neighbour search then we can use Hashing or Hashtable for the dictionary.Trie: It can be a good option if we want to add prefix and fast lookup. But, it takes more space than other data structures.Ternary Search Tree: If we want all the qualities like trie but do not want to give the more space then we can use ternary search tree.BK-tree: BK-tree is one of the best data structure if we want specifications like spell checker, find the similar word, etc.6) How can you find a unique word from a String which also has duplicate words?We can find the unique word from a string by using HashMap, Set and Regex.Candidate can also be asked for questions like:Implement Snake and Ladder game and find the minimum number of moves required to reach from 1 to 100 in a given game, using Dynamic Programming.Model a data structure for a DFA that takes an event as parameter and performs a desired action.Solve the three mislabelled jars problem.How to compare two binary trees?How to prove that in a tree the number of internal nodes is one less than leaves?Technical third round or director RoundThis round is a challenging round as in this round the manager ask the questions based on your projects, so candidate must have in-depth knowledge about their project which they have done and some problematic puzzles which candidates needs to solve.1) Write an algorithm for the tower of Hanoi?Tower of Hanoi is a very popular mathematics puzzle. In this puzzle, we are given three disk and three rods. Disks are arranged in the first rod like a stack, in ascending order. We need to transfer the disk from the first rod to third in the same order.There are some rules as well:We can move one disk at one timeWe can only move the uppermost diskDisk always should be in ascending order, i.e., a bigger disk cannot put on a smaller one.Algorithm:Let's suppose there are thee towers Beg, Aux, and Dest, and there are two disks where n disk is larger disk and n-1 is smaller one.StartStep 1: shift n-1 disk from tower Beg to AuxStep 2: shift n disk from Beg to EndStep 3: shift disk n-1 form tower Aux to C.Tower(n, Beg, Aux, Dest) Begin If n=1 then, Print: Beg-> Dest; else Call Tower(n-1, Beg, Dest, Aux); Call Tower(n, Beg, Aux, End); Call Tower(n-1, Aux, Beg, End); endif End 2) Write a code to find the loop in a Linked list? How will you remove this loop?#include #include struct Node { int data; struct Node* next; }; /* Function for removing the loop. */ void remLoop(struct Node *, struct Node *); /*Function to remove and detect the loop*/ int detAndRemLoop(struct Node *list) { struct Node *p1 = list, *p2 = list; while (p1 && p2 && p2->next) { p1 = p1->next; p2 = p2->next->next; /*if p1 and p2 will meet at some point which means there is a loop*/ if (p1 == p2) { remLoop(p1, list); printf("Loop is occurred\n"); /* Return 1 if loop is found */ return 1; } } /* Return 0 if there is no loop*/ return 0; } /* Function to remove loop. */ void remLoop(struct Node *loop_node, struct Node *head) { struct Node *ptr1 = loop_node; struct Node *ptr2 = loop_node; // Count the number of nodes in loop unsigned int k = 1, i; while (ptr1->next != ptr2) { ptr1 = ptr1->next; k++; } // Fix one pointer to head ptr1 = head; ptr2 = head; for (i = 0; i next; while (ptr2 != ptr1) { ptr1 = ptr1->next; ptr2 = ptr2->next; } ptr2 = ptr2->next; while (ptr2->next != ptr1) ptr2 = ptr2->next; /* Set the next node to Null to fix the loop */ ptr2->next = NULL; } /* Function to print linked list */ void printList(struct Node *node) { while (node != NULL) { printf("%d ", node->data); node = node->next; } } struct Node *newNode(int key) { struct Node *temp = (struct Node*)malloc(sizeof(struct Node)); temp->data = key; temp->next = NULL; return temp; } int main() { struct Node *head = newNode(40); head->next = newNode(15); head->next->next = newNode(12); head->next->next->next = newNode(10); head->next->next->next->next = newNode(4); /* Create a loop*/ head->next->next->next->next->next = head->next->next; detAndRemLoop(head); printf("Linked List after removing loop \n"); printList(head); return 0; } Output:Loop is occurred Linked List after removing loop 40 15 12 10 4 3) How will you design a data structure for excel spreadsheets?We can design an excel spreadsheets by using:Two-dimensional array ( but it will take lots of space)Sparse matrixMap, etc.4) Explain memory protection in OS.Memory protection is a mechanism which controls the unauthorized access of memory in the computer. Memory protection prevents the unallocated memory access by a process. Memory address is first checked before used by a process, to see whether it is allocated address or not.There are two registers LBR and UBR are used to implement memory protection.5) What is Virtual Memory in OS?Virtual Memory is memory management technique of Operating System. Virtual memory is an extra space provided to a program when a main memory does not have the sufficient space to execute a code. It temporarily transfers data from RAM to disk storage, which uses inactive memory of hard disk, which is termed as Virtual Memory.6) Write an algorithm to insert an element into a sorted linked list?Suppose the linked list is sorted in ascending order then following is the algorithm for the same. Let the input node is 13 and let assign as nSuppose Input linked list is:3 8 11 15 20 1) If given linked list is empty then assign the node as head and return it.2) If value of the node n is less than value of head node, then insert the node at start and assign it as head.3) In a loop, search the appropriate node after which the input node is to be inserted. To search the appropriate node start from head, keep moving until you reach a node x(Let?s suppose 15)whose value is greater than the input node. The node before the x will be the appropriate node(11).4) Insert the node(13) after the appropriate node(11) found in step 3.After insertion:3 8 11 13 15 20 7) Find pair of elements whose sum equal to a given number?#include void Pair(int arr[], int n, int sum) { for (int i = 0; i

The Interviewer may even ask about the total number of subjects in your Graduation, last semester subjects, your favourite subjects etc. The time will be around half an hour.Some of the questions are:1) Explain your major project.Answer: My major project was an android online application named Chat App to chat with friends, to share the images, files, to invite the peoples etc., having good security and privacy concerns. The project was a real-time based application connected with firebase. My project supervisor helped me a lot to complete my project on time.2) What are your favourite subjects?Answer: My favourite subjects are Data Structures, Compiler, Networking, Core Java, Software Engineering, Discrete Mathematics, Software Project Management, Big Data, and Digital Electronics.3) What is Polymorphism?Answer: Polymorphism is a concept by which we can perform a single action in different ways. Polymorphism is derived from 2 Greek words: poly and morphs. The word "poly" means many and "morphs" means forms. So polymorphism means many forms.4) What is the difference between Abstraction and Interface?Answer:ABSTRACTIONINTERFACE1.An abstract class can have abstract and non-abstract methods.An Interface can have only abstract methods. Since Java 8, it can have default and non-static methods also.2.Abstract class doesn't support multiple inheritance.Interface supports multiple inheritance.3.Abstract class can provide the implementation of interface.Interface can't provide the implementation of abstract class.4.The abstract keyword is used to declare abstract class.The interface keyword is used to declare interface.5) What is Encapsulation in Java?Answer: Encapsulation in Java is a process of wrapping code and data together into a single unit, for example, a capsule which is mixed of several medicines.We can create a fully encapsulated class in Java by making all the data members of the class private. Now, we can use setter and getter methods to set and get the data in it.The Java Bean class is the example of a fully encapsulated class.6) What are the layers of OSI model?Answer: Layers of OSI model are:Application layer ( 7th Layer)Presentation layer (6th Layer)Session layer (5th Layer)Transport layer(4th Layer)Network layer(3rd Layer)Data Link layer (2nd Layer)Physical layer(1st Layer)7) What is UNIX?Answer: UNIX is a complete package of the operating system developed mainly for servers, workstations, and mainframes.

In this round, candidates are asked questions on the basis of technical skills such as C, C++, Java, and Networking. Following are some sample questions with an answer to practice for technical round.1) Differentiate between abstract class and Interface in Java?Abstract class and interface both concepts are used to accomplish abstraction in Java. The primary differences between abstract class and Interface are:The abstract keyword is used to create an abstract class in Java, whereas interface keyword is used to create Interface.An abstract class can have both abstract and non-abstract methods whereas Interface can only have abstract methods.As a general class, abstract class also does not support multiple inheritance, whereas an interface supports multiple inheritance.An abstract class can extend other class and implement interfaces but an interface cannot extend class. It can only extend other interfaces.An abstract class may or may not have methods with implementations, but Interface cannot have method implementation.2) What are the static variable and static block?Static variable: If we use the static keyword with a variable then it is termed as a static variable. Static variables are the part of the class not, the instance. When we declare any static variable, then it creates a copy in memory which is shared between all the objects. Static variables are not thread safe as it is shared between various objects. Static variables are mainly used for memory management.Syntax:static variable_name; Static Block: A block inside a class with the static keyword is called a static block. A static block is executed at the time of class loading and before the execution of the main method. Static block is primarily used for initialization of the static variable. A class can have multiple static blocks, and they execute in the sequence as they appear in the program.Syntax:static{ // code to be executed } 3) What do you understand by TCP/IP?TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a suite of protocols TCP and IP, used for the communication over a network. TCP/IP protocols provide some standard rules for communication between two or more computers over the network. The TCP protocol at the transport layer divides a message or data into packets form and then resembled the packets at the destination part. IP protocol at Network layer is responsible for the moving of these packets to the correct destination.4) Which is the fastest sorting algorithm?There is no such specific fastest sorting algorithm because it depends on various factors and all the sorting algorithm gives different performances for different input cases. Although among all the sorting algorithm we can consider Quicksort as a fastest algorithm as it shows time complexity of O(n log n) for the best case and average case and O(n^2) for the worst case.5) What is tunnelling and tunnelling protocols? Explain their applications?Tunnelling is also known as port forwarding. These are the communication protocols which allow the secure data movement from one network to another network. Tunnelling enables communication from the private network which sent across the public network, and such process is called as encapsulation.In tunnelling process, data is converted into the form of packets, which travels through the tunnel. As data packets are moving through the tunnel, they got encrypted by the encapsulation process and when these packets reach the correct destination, then these packets are de-encapsulated and de-encrypted, and the packets again converted to the original data.Main tunnelling protocols are:PPTP: PPTP stands for the point-to-point tunnelling protocol. PPTP is available for Windows, Linux, and Mac. This protocol keeps data secure even in the public network. It works with the virtual private network which can be accessed by an authorized user.L2TP: L2TP stands for Layer 2 tunnelling protocol, which supports VPN. It depends on the encryption protocol for the encryption of data which passes through the tunnel.Application of tunnelling protocols:Tunnelling is used in cases where high-level security is required for data transmission over the network.It is helpful for encryption and decryption of data.6) Explain Polymorphism in Java?Polymorphism in Java is an important feature of Object Oriented Programming (OOP), which defines a single object with different forms. With the help of polymorphism, one action can be done in various ways.There are mainly two types of polymorphism in Java:Run-time polymorphismCompile-time polymorphismRun-time polymorphism: Method overriding is used to achieve Runtime polymorphism. It is also called Dynamic polymorphism or Dynamic method dispatch. In Run-time polymorphism, when we call an override method, it is resolved at run-time, hence it is called as run-time polymorphism.Compile-time polymorphism: Method Overloading is used to achieve the Compile time polymorphism. It is also called as Static polymorphism and when we call the method, it is resolved at compile time only. That's why it is called as Compile-time polymorphism.7) What do you understand by Pointer arithmetic in C?As we know Pointer is a variable which holds the address of another variable and that variable is a numeric value, so any arithmetic operation performed on a pointer is termed as pointer arithmetic. But we can only perform some limited arithmetic operations on the pointer, which are given below:IncrementDecrementAdditionSubtractionComparison8) Explain the difference between packet switching and circuit switching?The Packet switching and circuit switching both are the switching methods which are used to forward the data packets from the sender to receiver destination.The main differences between the Packet switching and circuit switching are given below:Packet SwitchingCircuit SwitchingIn packet switching, data is divided into small parts, termed as packets and then these packets are transmitted from source to destination.In circuit switching a physical path is established between two endpoints for data transmission.Packet switching is connectionlessCircuit Switching is connection oriented.Packet switching can be implemented at the network layer of the OSI model.Circuit switching can be implemented at the physical layer of the OSI model.It is mainly designed for data and voice communication.It is basically designed for voice communication.Congestion occurs at the time of data transfer phase.Congestion occurs at the time of connection establishment.9) What do you understand by CDMA?CDMA is the acronym for Code-division multiple access, is a standard for the wireless digital cellular network. CDMA is a type of multiplexer, where various transmitters can transmit information simultaneously over a single communication channel. CDMA uses spread-spectrum technology and special coding scheme for data transmission. Various protocols, which are used for 2G or 3G wireless communication, refer to CDMA.10) What do you understand by demodulating a signal?Demodulation of a signal is a method of extracting the original information of signal from a carrier wave. An electronic circuit which is used for demodulation is called as a demodulator.11) What do you understand by telecommunications?Telecommunication refers to the transmission of any signal, data or any type of information by physical or wireless medium over a significant distance. When the exchange of information between the sender and the receiver occurs with the help of technology, then it is known as telecommunication. In telecommunication there is a communication arrangement with a transmitter and a receiver. At any station, a device which combined the transmitter and receiver is termed as a transceiver.Basic Elements of Telecommunication System:Transmitter: Which takes the information and convert into the form of a signalTransmission medium: A medium over which signal travels it may be an optical fibre cable, or free space.Receiver: Which receives the signal and convert into a usable form.12) What are the various advantages of GSM?GSM is an acronym of Global System for Mobile communication. It defines the standard protocols for the second-generation digital cellular network used by mobile devices.Advantages of GSM:GSM allows a reliable and efficient way to transfer data. It also allows transferring text and pictures.GSM provides better security during the conversation. It ensures that only the caller and receiver are in conversation during a call.GSM provides the worldwide facility of calls and data transfer, but it may cost high on the international level.GSM cell phone has clear sound quality, as it filters background noise.13) What are the various applications of DSP?DSP is termed as Digital Signal Processing. It is a part of signal processing which is used to perform a variety of signal processing. DSP unit analyses and modifies a signal to increase its performance and efficiency.Various applications of DSP in communication:DSP is used in audio signal processing.DSP is used in encoding the waveforms.DSP is used for Audio compression.DSP is used for Digital image processing.DSP is used for speech processing.DSP is used in RADAR, biomedicine, weather forecasting, and many more applications.14) What do you understand by commands?Commands are the specific instructions given by the user to the computer?s operating system, to perform a particular task. We can input these commands using the command line interface provided by the operating system.15) Why we use Jump statement in C++?Jump statements are used to disturb the normal flow of program unconditionally. There are three types of Jump statements available in C++.BreakContinuegoto.16) What do you understand by MAC address?MAC address stands for "Media Access Control" Address is a unique identification hardware number, which uniquely identifies each device on a network. The MAC address is a computer's unique hardware number which can be determined by Ethernet or Wi-Fi card. A MAC address is of 64 or 48 bits, which is expressed in hexadecimal forms separated by colons such as 2AA:EF:EF3E:2A1B.17) What do you understand by nested loop?If a loop exists inside another loop, then it is termed as a nested loop. Or a loop within a loop is called a nested loop. When we use a nested loop in our code then control passes to the outer loop, then for first iteration it executes its following loop and other conditions and so on and repeats until the outer loop finishes.Syntax:for(int i=0; i

As there are various face-to-face interview rounds so different interviewer can ask different types of questions. The types of questions can also vary as per different positions. SpaceX provides lots of career path for different roles.A list of some interview questions with answers for the preparation of the interview.1) Write a program to reverse the words using an array?#include #include void main() { int i, j = 0, k = 0, x, size; char arr[100]={"This is reversing the words"}; char arr1[10][20], temp; //2d-array for (i = 0;arr[i] != '\0'; i++) { if (arr[i] == ' ') //for checking space { arr1[k][j]='\0'; k++; j=0; } else { arr1[k][j]=arr[i]; j++; } } arr1[k][j] = '\0'; /* reverses each word of a given string */ for (i = 0;i 18) Describe your Projects?The answer to the above question will be different for each candidate. The interviewer wants a detailed explanation of the projects which have candidates have already performed. The Candidate needs to have a good knowledge for every project of the technology which he has used, a concept which he has used and even every small knowledge of the project is required.19) How will you find a loop in a singly linked list?/*pro public class Detectloop{ private Node head; private static class Node { private int value; private Node next; Node(int value) { this.value = value; } } public void addtoList(Node node) { if (head == null) { head = node; } else { Node temp = head; while (temp.next != null) temp = temp.next; temp.next = node; } } public void printList() { Node temp = head; while (temp != null) { System.out.format("%d ", temp.value); temp = temp.next; } System.out.println(); } public boolean ifLoopExists() { Node fastPtr = head; Node slowPtr = head; while (fastPtr != null && fastPtr.next != null) { fastPtr = fastPtr.next.next; slowPtr = slowPtr.next; if (slowPtr == fastPtr) return true; } return false; } public static void main(String[] args) { Detectloop dl = new Detectloop(); // Creating a linked list Node loopNode=new Node(12); dl.addtoList(new Node(10)); dl.addtoList(new Node(8)); dl.addtoList(loopNode); dl.addtoList(new Node(5)); dl.addtoList(new Node(4)); dl.printList(); // creating a loop dl.addtoList(loopNode); // Test if loop existed or not System.out.println("Cycle exist in list-->" + dl.ifLoopExists()); } } Output:10 8 12 5 4 Cycle exist in list-->true 20) Is it possible to go to an infinite loop for the following program? void fun( int* arr , int arr_size ) int i = 0; for( ; i "I have won the award for the innovative employee of the month in my last company. We have given a project, which was needed great innovation for the accomplishment of that project, and I decided to be the leader for that, and I with my team have successfully completed that project, and also that was one the of the best project of the company."13) How would you inspire and encourage ideas in others?The interviewer wants to check your leadership qualities and thinking capability by this question.

Once the CEO of Amazon, Jeff Bezos said, "I'd rather interview 50 people and not hire anyone than hire the wrong person."You can understand the quality of the recruitment process of Amazon by the statement of their CEO. It doesn't mean Amazon wants you to fail. Instead, it simply means they only want to hire people who prove themselves worthy.In this article, we will explain the interview process of Amazon, the technical topics you have to prepare for discussion, and how to answer the interview questions asked by the interviewer.Amazon's Interview ProcessThere will be a total of 5 rounds (1 online coding test + 4 interview rounds) in the whole process.69M1.1KHello Java Program for BeginnersRound 1 (Online coding test Round)This test contains two coding questions for which you have to be given 2 hours to solve. You also have to submit the approach used for solving in words and your algorithm's time and space complexity.Round 2 (Technical Round)You will get 2 to 4 coding questions that focus on basic problem solving and data structures in this round. The questions may vary according to your experience level. The less experienced you are, the more number of coding rounds you will face.Round 3 (Design Interview Round)In this round, the candidate may ask a question on high-level design architecture for real-life products and OOPS-based design of components. The company may skip this round for entry-level openings for the software engineering role.Round 4 (Hiring Manager Round)This hiring manager round is used to test for cultural fit based on attitude and previous work experience. In this round, the candidate is asked about the general HR questions and the previous company's experience. The interviewer may discuss your projects in the previous company and ask some behavioral questions based on those experiences.Round 5 (Bar Raiser Round)This is the last interview round called the optional bar raiser round, which combines all of the above. Here, a senior engineering manager can ask about your previous works and again ask some behavioral questions. The idea is to judge if you are technically better than an average person in a particular Amazon team.Technical topics you must prepare for Amazon's Interview.Programming LanguageAmazon doesn't ask for specialization in any specific programming language before attending an interview for a tech position. But you must be familiar with the syntax of languages such as C/C++, Java, Python, C# or Ruby. You should also know how memory management works or the most commonly used collections, libraries, etc.Data StructuresThis is the most important technical topic you should prepare for. Most of the work Amazon do involve storing and providing access to data in efficient ways. So you must have a good knowledge and understanding of the inner workings of common data structures and compare and contrast their use in various applications.AlgorithmsYou must have the knowledge and a good understanding of the most common algorithms such as traversals, divide and conquer, breadth-first search vs. depth-first search etc. and make sure you understand the trade-offs for each. Please focus on the learning of implementation strategies of different classes of algorithms rather than memorizing them.CodingYou may be asked to write syntactically correct code rather than pseudocode. Try to write code without an IDE. It would be best if you practiced coding with a pen and paper. It will be helpful at the time of the interview. The company prefers the candidate who writes scalable, robust and well-tested code. These are the main evaluation criteria for your code.Object-oriented DesignObject-oriented design is the best practice to write good software because good software design is critical to success. Your software needs to be extensible and maintainable. So, you should have a working knowledge of a few common and useful design patterns and know how to write software in an object-oriented way.DatabasesThe company prefers candidates who have a good knowledge of the non-relational database. Amazon has developed Amazon Web Services such as DynamoDB so that their developer community can easily leverage the benefits of non-relational databases. So, it is good if you know relational and non-relational databases.Operating SystemsThe candidate must be familiar with some Operating System topics to enhance the performance of the code. (e.g. memory management, processes, threads, synchronization, paging and multithreading).Internet TopicsYou must know the fundamentals of the internet, such as how browsers function at a high level, from DNS lookups and TCP/IP to socket connections.Basic Machine learning and Artificial IntelligenceYou must have basic knowledge of machine learning and artificial intelligence such as data-driven modeling, train/test protocols, error analysis and statistical significance. It would help if you visited your Machine Learning and Artificial Intelligence textbooks to prepare for these topics.Some examples of technical Interview QuestionsThere are two integer arrays A and B, of size N given. There are N gas stations along a circular route, where the amount of gas at station i is A[i]. You have a car with an unlimited gas tank, and it costs B[i] of gas to travel from station i to its next station (i+1). You begin the journey with an empty tank at one of the gas stations.Return the minimum starting gas station's index if you can travel around the circuit once, otherwise return -1.You can only travel in one direction. i to i+1, i+2, … n-1, 0, 1, 2.. Completing the circuit means starting at i and ending up at i again.The question says that we have two arrays of int. The first one is cost, and another one is gas. We have a car and need to travel to "n" places where n is the above two arrays' length.Now, according to the question, we can start from a point. Let's say 3, so that means to reach the next point, we need gas greater than the cost at 3.See the example:Suppose the gas array is: {1, 2, 3, 4, 5}And the cost arrays is: {3, 4, 5, 1, 2}Here, we can see that the 3rd term from gas is: 4 (Index starts from 0).And the same for the cost is 1, so to go for the 5th position our gas should be greater than the cost. As we can see in this case, it is as 4 > 1.Here you see that this much gas is used to go to the next point. Even after reaching there, you will leave with 3 gas as 4-1=3.So, at the next point, you will initially have 3 units of gas.Now, the question is asking from which point we should start so that we can traverse all the points.Now, let's take the gas array and cost array as following:gas = {1,2}cost= {2,1}Now, let's start from the first element that is index 0.So, the gas in our car after first travel will be = gas[0]-cost[0] = 1-2=-1.Since it would be a negative number, that means we can't traverse using the 0 index.Now, let's start from the second element, that is the index 1;The gas in our car after first travel will be = gas[1]-cost[1]=2-1=1.We have left with 1 unit of gas, after that we will come to the 0th index so we will be having = 1+gas[0]-cost[0]=1+1-2=0So, that means we will be able to complete our journey from the 1 index.So, there are two ways to solve this problem:The first solution would be to use two loops and check whether the index exists but will take higher time and O(n²) time complexity.Another way to solve this problem is to follow the steps given below:Take a variable start and initialize it to 0, and another variable end and then initialize it to 1.We will loop from start to end and keep increment end until it reaches the same value as the start. For example, if our array is of length 5 then: 1->2->3->4->0. In that case, we will know that start is the index from where the answer comes from.For storing the current gas in our car, we will use another variable curr and then if at any point of time, if curr becomes negative, that means that index cannot be the starting point. In that case, we will increment the start by 1.Here, the main problem is that we know how to move forward in an array. I mean, we know how to increment the current pointer. But how do we get back? Here, the pointer goes like this: 1->2->3->4->5->6……. and so on. It won't come back like: 1->2->3->4->1.To solve this problem, we have to use a simple trick. Instead of increment the value like : n=n+1, we will use : n=(n+1)%length.In that case, when the pointer gets to the end, it will again start from zero.See the complete code for the solution of the above problem:public int canCompleteCircuit(int[] gas, int[] cost) { if(gas.length==0){ return -1; } if(gas.length==1){ return gas[0]-cost[0]The situation of the issue or the task you were given.Describe the actions you took to resolve the situation or complete the task.Explain what you learned from the experience.Explain the Positive side: In some cases, missing a deadline is not in the employee's control. If that is true of your situation, you can use it as your advantage and emphasize that the only reason it happened was because of an outdoor event. However, that is not always possible. In these types of cases, you must highlight the result or what you learned and how you improved.If you are solely responsible for the deadline and have described the mistake you made, don't leave your interviewer with a negative image. Instead, make your answer work for you by ending your response with a very positive, clear message about what steps you took to improve and where you are on reaching your goals.Be Confident: If the interviewer asks you to share a story about your failure, don't lose your focus and confidence. Remember, everyone has made small or big mistakes. Explain how you move on from that incident by learning something new.Example of a good sample answer:Once I was given a deadline to write an article for a client on a short turnaround time. I believed I could handle the article in addition to the workload I already had, but I miscalculated how long it would take me to write it. The morning the article was due, I realized I would not make it in time and contacted my boss to explain the situation. I apologized, explained what happened and asked for an extension, which he granted. I learned that I need to be honest with myself about the workload I can handle each day. I also learned that when accepting assignments, I need to include a time buffer to ensure that even if unforeseen events arise, I can meet my deadlines.8) What would you do if you found out that your closest friend at work was stealing?This question is asked to check your loyalty towards the company as well as your friend. You should consider the nature of the offense before deciding how to proceed.According to the question, your friend's act is unethical, so you should tell the company about your friend's act. You can give a chance to your friend and warn him earlier.9) If your direct manager instructed you to do something you disagreed with, how would you handle it?By asking this question, your interviewer wants to know how you handle disagreement. This is also helpful to check your negotiation skills. You can explain your communicational flexibility and convey to the interviewer that you aren't averse to speaking up. You believe in communicating till you find a solution.10) What would you do if you saw someone being unsafe at work?You can tell the interviewer that you have a duty of care to yourself and your colleagues. If you find these types of circumstances, you will warn the person that he is working can lead to an accident. If you know a safer way to do the job, you will suggest it. Otherwise, you will call your supervisor.
