Aristocrat Leisure Interview Questions and Answers

Round: Resume Shortlist
Experience: Since I got a Pre placement offer through Internship so my experiences will be in accordance to Internship
procedure. Placement procedure is almost the same. They look for decent
pointers. In addition to this they would consider if you have some good
technical background. They look for committed people who have an experience of
working in teams.For this they float a from of their own which has some questions answers of which more of less lies in the resume. There are some HR questions too like Long term goal , Short term goal, SOP, mind over matter (the most catchy one). If you get selected for interview round your interview will be around this form .

Round: Group Discussion
Experience: It was my first GD. There were around 120 people selected for the GD. We were
divided in the groups of 10. As expected my group was very tough as there were
better speakers. We were given a paper containing the situation and options. We
were given a total of 20 minutes which included the time for reading and
understanding the situation. Someone started speaking after around 5-6 minutes
followed by an another guy. Next , I had to dive in as if I would have delayed
I would have ran out of ideas which would have been taken by the others. I
started confidently and as time passed by I was successfully able to convince
the people towards my option or I must say there were no arguments towards my
option. Out of expectation, I cleared this round. Next round was the interview round.
Tips: - GD is all about convincing the junta towards your option.- Never speak when some one else is speaking.- Don't be negative , always give positive statements- Never take name of any person sitting in the room in the GD even if you know him/her- Never point fingers- Sometime GD can become a fish market. Stay out of it and wait
for the right time to speak.

- Don't shout

- Don't be an orator if you are not a good speaker

- Read the paper carefully and jot down the pros and cons of
every option so that you have many points to speak to

- It does not really matter how much did you speak but what you
speak matters, don't panic if you have spoken less during GD. Sometimes giving
1-2 logical statements gets you through.
Duration: 20 minutes

Round: Technical Interview
Experience: Around 35 people were selected for this round. We were told there will be 2 rounds of interviews. I got a call for my Technical interview soon. It was a large room with only 3 of us - myself and the 2 interviewers. They started by greeting themselves and asked me to tell something about me. I started confidently and told them about myself, my birth place, interests, college life, IIT B Racing etc. Then the interview shifted to specific questions. I covered every important point in the resume and explained it in a line or two as the questions went. They seemed impressed as I had Cummins on my resume as I was the only one in my batch who did intern over there. Also, having IIT B Racing played a major role in getting me through. They asked some questions around that and I was able to answer them successfully. I could not answer initial questions completely but was confident in whatever I said. This confidence helped me to answer later questions in a better way and they were quite impressed. Frankly , I did not have any hopes till now that I will get into ITC, so I felt stress free during the interview though it was my first interview. After answering every answer confidently they asked me some questions regarding my hobbies - Cricket mostly. Since I have been a die hard fan of cricket and love to play it, my energy level went to a higher level during this discussion. Finally , they asked do you have any questions for us ? I asked what will be my work profile if I get in. They explained me the profile and I liked it. I requested them to work on some project which will create impact on the company rather than doing some research or paper reading work. They smiled and assured me of that. So, finally this interview ended after around 25 -30 minutes. I was expecting the call for second interview. (People who cleared 1st round only got a chance for second HR interview) but not that soon. It was hardly a minute after my interview got over , a person from behind calls out my name and says "You have a second interview in a minute. Are you Ready for it ?" . I was happy but exhausted. I had no other option and said politely "Yes"
Tips: - Be confident
- Don't give arbit answers if you don't know. They are very knowledgeable people and will easily catch you if you are giving vague answers.
- Don't panic if you are unable to answer some questions. Its perfectly fine . Just say politely you don't know/remember.
- Maintain a positive body language
- Show them that you are willing to work for them for a long period of time. Don't give the slightest intention of leaving the company for any reason.
- You should be able to justify every point in your resume or whatever you write.
- Revise the form before interview , the one ITC asked you to fill in the initial process of selection
- Wear good formals. During my time some people gave interview in Jeans. This does not give a professional look. Also carry a pen.

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.

Round: Other Interview
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.
