Round: Case Study Interview
Experience: No one would be eliminated in this round. They will provide you ample time - around 40-50 minutes to write a response on a case study. The topic would be new and unheard of, but you can think and write peacefully in that amount of time.
Tips: Make sure you highlight the points made and do remember them for the Group Discussion phase.

Round: Group Discussion
Experience: One-third of the guys will get selected for the interviews from each group of 8-10 guys. The topic of the GD would be same as the case study. Now, its time for you to recall the points you made during the writing section. The GD will last for around 15-20 minutes.
Tips: Good communication skills, relaxed but expressive tone. Don’t be silent and try to speak up whenever you get a chance. Try to bring new air into the discussion and think from all the different perspectives. You should speak at least 2-3 times, even if you just say 1-2 sentences each time. That will do. They also individually ask each person to speak, specifically those who could not speak, but you had better not be that guy or girl. There is no need to fight for summarizing the GD. Try to show that you are involved throughout the GD.

Round: HR Interview
Experience: There will be two guys, one from technical and the other HR. They both ask questions at the same time and they discuss among each other as well. They mostly try to detect any fraud or fake thing you did in your project or intern. All the technical questions come from your CV. So, your fate is kind of in your hands only.
Tips: Prepare hard for Projects, Internships etc. Don’t panic. They try to see how you react in a pressure situation and actually behave as if you are not impressing them. Just be calm and keep on speaking. If there is something you want to say and they interrupt you, its better you ask them to give you a chance to explain it in details. Do have a few questions in mind to ask them about your job profile and Wipro. That is the final nail in the coffin.

Skill Tips: A minimum CGPA of 8.0 was mentioned and later they relaxed it to 7.9. They were giving quite some importance to the Internships and Projects undertaken and were trying to judge if you actually did something new and genuine. They were dwelling deep into it. As I said, prepare well for them just like you prepare for BTech Project Viva. They do ask a lot of questions.HR questions should be prepared thoroughly. A background check of Wipro and IT sector companies is a must. Prepare well for group discussions. Try to get background information about the IT sector and the company. Prepare your CV thoroughly.

Round: Test
Experience: Deloitte selection procedure involves a written test which is
same as CAT format (certainly not that tough). Though I had not joined any test series to prepare for it, but I must strongly recommend that you should actually join a test series (provided by Career Launcher or
TIME). This test series will actually help you to synchronize your mind to the format and moreover it would help to refresh the question solving skills which you used to exercise while preparing for JEE.

Round: Group Discussion
Experience: general topic is given (mostly it is as to how you would go for implementing a new type of technology in a company, and hence you all have to decide the stepwise procedure for the implementation), then whole of the group is called in presentation room where each one is told personally to speak about the same topic as that of GD. This constitutes
second round. Finally, if you clear it, you get to face the interviews.
Tips: From now onwards, start reading newspaper daily. Just give at least one hour reading the editorials from newspaper and make it your habit. Not only for GD's, but for life in general, its very important that you should have a certain view about things happening around you and in the world and newspapers are the best thing which help you form your views and also know about the expert opinions on day to day topics. So, make sure that you read newspaper daily.

Round: Other Interview
Experience: For interview, main thing is that you should be well conversed about everything you have mentioned on your resume. So, before you go for any interview, just make sure that you can speak about for 5 minutes on
every single thing in resume. Deloitte is a company which is open for all the btech students and hence its mainly looking for the students who have a right attitude and are good at their interests.
Tips: have a perfect set of communication skills. I had not done
any special type of preparations for the interview or group discussions but all these skills actually developed during these years. I would advise that in order to gain more confidence at speaking, you should start taking challenges from now on and should actively participate in any sort of debates and GD.

Round: Group Discussion
Experience: GD was not a round included for Capgemini placement test,Pearson versant english test was there once you clear your apti but due to technical faults GD was the round taken.There was a group of 10 people and we were given topic and 5 mins for preparation then GD was started.I was the second one to speak on the topic,I was in the favour of MNC because I really feel that for freshers Indian IT company is not very great start.Rather if one starts with MNC then it gets a brand name associated with them and also global exposure for one.And also Indian IT sectors are largely collaborating with the MNCs so for fresher MNC is a good start than Indian IT company.
Tips: I will suggest you to understand the topic well,jot down the points you want to say and then always initiate for the GD do not argue,just humbly disagree to the topic,do not get personal in it...as soon as you start the supervisor judges you so do not hesitate and just put your points confidently only your English is judged by this...

Round: Test
Experience: 1 Written Test - (20 MCQ + 2 Coding Questions) on HackerRankAmazon visited our Campus on 28th July. In the morning the recruitment process started with the Written Test. It was taken on Hacker Rank which comprised of 20 MCQ Questions followed by 2 Programming Questions. MCQ Questions usually contain questions on C, DBMS, OS, and 4-5 Logical Questions. One should be aware that the Hacker Rank platform keeps record of how much time you have spent on each Question and after spending so much time did you attempt it or not. The 2 Coding Problems were quite easy. Only speed and accuracy was required to crack this round.Written Round Coding Question -1) A Linked List was given and we had to swap the ith node with (n-i+1)th node.2)(given some intervals), merge the common Intervals.I coded both the problems and passed all the test cases of the first question and half of the test cases of the 2nd Question. By the evening the results of the written round were declared and the Interview Process started. I rushed to the Design Centre and while I was arranging my grade sheets and my resume , something totally unexpected happened. One of the Amazon Employees who was also an Alumni of MNIT Jaipur walked up to me and told me that I have done very well in the Written Test and I was ranked 2nd based on the Written Test. He wished me ‘Best of Luck’ and told me to calm down and give my best. Talking to him really motivated me a lot. At the same time I was shocked that he still remembered my name even after an year, as we had talked only for a couple of minutes during my Internship Process in Amazon in which I was among the last 3 Students who went to the final round but was not selected. Apart from the students shortlisted from the written test, Amazon also shortlists around 5-6 more candidates based on their CGPA and some other factors. But it should be noted that at any time during the Recruitment Process, Cumulative scores can be considered.
Tips: CGPA above 8 should definitely be maintained.
Total Questions: 22

Round: Technical Interview
Experience: The Interview Process started with around 25 candidates. I was among the first few with whom the Interview had started which went on smoothly



Questions of Interview Round II –



1) A String was given with a lot of words in it and I had to reverse all the words
2) A String was given and I have to swap word by word from the  beginning to the end.
3) In question 2 when there are ‘n’ in the String whose position shouldn’t get affected during the swapping process
4) Continuation was when more than 1 ‘n’ occur together.



I was asked to code the above, and told them about the time and space complexities. Then he went through my resume and based on my projects he appreciated my interest in OS. and asked me a Question –


You have a large game and a small memory, so how will you play the game.
I told him the concept of Virtual Memory and how it makes it possible to run such a game. Then he asked me whether there is any limit or constraint on the size of the virtual memory. I explained to him if the amount of memory required at any particular moment of time to run the game, itself exceeds the available size in the RAM for the user, then we won’t be able to play. Then he asked “Suppose you have a 4 GB Ram then how much memory will be available to the user and what will happen to the other memory”. I explained that kernel occupies some memory and apart from that page tables and all are also stored in the memory. Then there were some discussions regarding my projects.

Experience: Around 17 students were shortlisted. The resumes of students and their academic projects were given importance while shortlisting for this round. It started at around 10PM.



Questions of Interview Round III –



1) There is a big file containing numbers and we have to sort all of them.



I mentioned the approach mentioned in GeeksforGeeks that for example the available RAM for this purpose is 100 MB. So we can break the File in chunks of 100 Mb and bring the chunks in Memory and first sort them individually. Then we can prepare a heap containing first elements from all chunks. And keep extracting min from heap and replace it by next smallest element of the chunk it belongs. Then he asked if the number of chunks being formed here are very large, that is the heap I am preparing won’t fit in 100MB, then what to do. I suggested some further modifications and finally he was satisfied with the solution.



2) How to implement word suggestions like that in Eclipse.



I explained that it can be done using Tree Data Structure or using some sort of multilevel hashing in combination with storing words in sorted form. He asked me time complexities and told me to think of further improvements. He wasn’t completely satisfied and moved onto the next question.



3) Given 2 integers a and b, the sequence which will be formed is a, b, a+b, a+2b….



i.e Current element = sum of the previous 2 elements.



So now given a number k, how to figure out if it lies in the sequence or not.



This Question is not as easy as it looks. Here a and b can be negative or positive so the Generated Sequence can contain all positive or all negative or alternate occurrence of positive and negative element in sequence. So till which point should we generate the sequence and decide that k can or cannot lie in the sequence. I wrote a code but he mentioned few test cases in which my code was failing. After a few modifications I was able to write a satisfactory code solving all the test cases.

Round: Other Interview
Experience: I answered both the questions and also mentioned  solution to kth largest if Deletion operation is also there and if it is not. Then he told me to write the code for Heapify Function. Again there were some discussion regarding my Projects.

Round: Other Interview
Experience: Questions of Interview Round V -
This round started with a detailed discussion about my Summer Internship Project in Wooqer. After that I was asked to introduce myself. Then he asked me -

1) Given an Infix expression, how to evaluate its answer.

I was asked to write the code for it covering all the cases and I was given half an hour to do it. I wrote it in about 15-20 minutes. Interview of 4th Round got over by about 9 PM, and the results were declared by 11PM.
Tips: Amazon mostly focuses on – Tries, Big Data, Hashing, Strings. Apart from my general preparation for the Interview, I had gone through around 60 Amazon Interview Papers available on GeeksforGeeks, so I was totally aware of the kind of Questions I would be facing in the Interview, and prepared myself accordingly. In this year’s Amazon Interviews mostly the questions asked were not directly from GeeksforGeeks. And few questions which were picked directly from GeeksforGeeks, the solution they were expecting for it was better than that mentioned in GeekforGeeks. But to guess such a solution, one should surely be aware of all the existing solutions in GeeksforGeeks.

General Tips: Self Projects have a very high weight age in one's selection because this is one of the many things that distinguishes you from other candidates sitting in the Interview. It also shows your capabilities and your field of Interest. Also, Summer Internship surely matters a lot in Companies like Amazon. There was a very detail discussion of my Internship at Wooqer during the Interview Process at Amazon so be prepared.
