It stores only temporary data.Memcached cannot cache large objects.Memcached is not application specific.Memcached is not fault-tolerant or highly available.8) In which conditions cache cannot retain the stored information?The cache cannot retain the stored information in following conditions:When the allocated memory for the cache is exhausted.When an item from the cache is deleted.When an individual item in the cache is expired.9) What is the difference between Memcache and Memcached?Difference between Memcache and Memcached:Table:MemcacheMemcachedMemcache module provides handy procedural and object-oriented interface to Memcached.Memcached is a high-performance, distributed memory object caching system.Memcache is an extension that allows you to work through handy object-oriented (OOP's) and procedural interfaces.Memcached is an extension that uses the libMemcached library to provide API for communicating with Memcached servers.The Memcache module provides a session handler (Memcache).The Memcached provides a session handler (Memcached).It is designed to reduce database load in dynamic web applications.It is used to increase the dynamic web applications by reducing database load. It is the latest API.10) Can we share a single instance of Memcache between multiple projects?Yes, we can share a single instance of Memcache between multiple projects because being a memory storage space, Memcache can be run on one or more servers. In Memcache, you can also configure your client to speak to a particular set of instances.We can also run two different Memcache processes on the same host being completely independent and without any interference. If you partition your data, it is important to know from which instance to get the data from or to put into.11) Explain the differences between SAP HANA and Memcached?SAP HANA is an in-memory RDBMS and mostly used for accelerating SAP applications while Memcached is a key/value caching system and used for accessing both RDBMS and NoSQL databases.12) How to connect Memcached server with telnet command?By using telnet hostname portNumber command, you can connect Memcached server with telnet command.Syntax$telnet HOST PORT ExampleThe given example shows that how to connect to a Memcached server and execute a simple set and get command.

After this, the same key is replaced with the "redis".add key 0 900 9 memcached STORED get key VALUE key 0 9 memcached END replace key 0 900 5 redis get key VALUE key 0 5 redis END 17) How to append the value of the key?By using append command, you can append the value of the key.Syntaxappend key flags exptime bytes [noreply] value ExampleIn the given example, we are trying to add some data in a key that does not exist. Hence, NOT_STORED is returned by Memcached. After this, we set one key and append data into it.append javatpoint 0 900 5 redis NOT_STORED set javatpoint 0 900 9 memcached STORED get javatpoint VALUE javatpoint 0 14 memcached END append javatpoint 0 900 5 redis STORED get javatpoint VALUE javatpoint 0 14 memcachedredis END 18) How to prepend value of key?By using prepend command, you can prepend value of the key.Syntaxprepend key flags exptime bytes [noreply] value ExampleIn the given example, we are trying to add some data in a key that does not exist. Hence, NOT_STORED is returned by Memcached. After this, we set one key and prepend data into it.prepend tutorials 0 900 5 redis NOT_STORED set tutorials 0 900 9 memcached STORED get tutorials VALUE tutorials 0 14 memcached END prepend tutorials 0 900 5 redis STORED get tutorials VALUE tutorials 0 14 redismemcached END 19) How to delete the key?By using delete command, you can delete the key.Syntaxdelete key [noreply] ExampleIn the given example, we use javatpoint as a key and add the value Memcached in it with 900 seconds expiration time. After this, it deletes the stored key.set javatpoint 0 900 9 memcached STORED get javatpoint VALUE javatpoint 0 9 memcached END delete javatpoint DELETED get javatpoint END delete javatpoint NOT_FOUND 20) How to show the stats?By using stats command, you can show the stats.Syntaxstats Examplestats STAT pid 1162 STAT uptime 5022 STAT time 1415208270 STAT version 1.4.14 STAT libevent 2.0.19-stable STAT pointer_size 64 STAT rusage_user 0.096006 STAT rusage_system 0.152009 STAT curr_connections 5 STAT total_connections 6 STAT connection_structures 6 STAT reserved_fds 20 STAT cmd_get 6 STAT cmd_set 4 STAT cmd_flush 0 STAT cmd_touch 0 STAT get_hits 4 STAT get_misses 2 STAT delete_misses 1 STAT delete_hits 1 STAT incr_misses 2 STAT incr_hits 1 STAT decr_misses 0 STAT decr_hits 1 STAT cas_misses 0 STAT cas_hits 0 STAT cas_badval 0 STAT touch_hits 0 STAT touch_misses 0 STAT auth_cmds 0 STAT auth_errors 0 STAT bytes_read 262 STAT bytes_written 313 STAT limit_maxbytes 67108864 STAT accepting_conns 1 STAT listen_disabled_num 0 STAT threads 4 STAT conn_yields 0 STAT hash_power_level 16 STAT hash_bytes 524288 STAT hash_is_expanding 0 STAT expired_unfetched 1 STAT evicted_unfetched 0 STAT bytes 142 STAT curr_items 2 STAT total_items 6 STAT evictions 0 STAT reclaimed 1 END 21) How to get the versions?By using Version command, you can get the versions.22) How to close the connection?By using the Quit command, you can close the connection.23) How would you update Memcached when data changes?There are two methods to update Memchached when data changes:By clearing the cache proactively: You can update Memcached by clearing the cache while insertion or updation is made.By resetting the cache: It is slightly similar to the first method, but it doesn't delete the keys and wait for the next request for the data to refresh the cache, it resets the values after the insert or update.24) What is Dogpile effect? How can you prevent this effect?If the cache expires, and websites are hit by multiple requests made by the client at the same time, this effect is known as Dogpile effect.This effect can be prevented by using a semaphore lock. In this system when value expires, the first process acquires the lock and starts generating new value.25) What happens to the data stored in Memcached when server accidentally gets shut down?In Memcached, data is not permanently stored. It is not a durable data so, if the server is shut down or restarted, all the data stored in Memcached will be deleted.26) If you have multiple Memcache servers and one of the Memcache servers fails which has your data, will it ever try to get key data from that one failed server?The data in the failed server won't get removed, but there is a provision for auto-failure, which can be configured for multiple nodes. Fail-over can be triggered during any socket or Memcached server level errors and not during normal client errors like adding an existing key, etc.27) How can you minimize the Memcached server outages?Following are the methods to minimize the Memcached server outage:When one instance fails, several of them go down, this situation will put larger load on the database server when the client reloaded the lost data. To avoid this, you should write your code to minimize cache stampedes, and it will leave a comparatively less impact.You can bring up an instance of Memcached on a new machine using the lost machines IP address.The Code is another option to minimize server outages as it gives you the liberty to change the Memcached server list with minimal work.Setting timeout value is another option that some Memcached clients implement for Memcached server outage. When your Memcached server goes down, the client will keep trying to send a request till the time-out limit is reached.

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 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.

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.

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.

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.

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.

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.
