Experience: Technical on paper test questions:(dis was only for 12 among d 26 shortlisted ppl after apti...others directly had interviews)
5 wer selected in this test who wer nw sent for interviews
TECHNICAL INTERVIEW: (pls list the questions asked in all the rounds)
26 shortlisted after apti (14 directly for interviews & 12 had one more technical on paper test...mentioned above)
der wer min 2 technical rounds for each of them...max were 5
- You are given course dependencies
A->B,C
B->D
C->A
D->nothing
The above dependencies mean...if you want to take course A...you should take courses B and C first....To take B,Course D must be taken first....D is an independent course and can be taken without any prior requirements.
Now you are told these dependencies.Come up with an appropriate data structure to represent these dependencies.Then write a code that finds out all the courses that the student can take up...in this case the student can first take course D because its independent.Now that course D has been taken he can next take up B as it depends on B alone...But the courses A and C can never be taken because they depend on each other...So here all the courses that can be taken are B and D.
After i wrote the code....he asked for all possible test cases
-Given an array of length N....It can be filled with nos. only from 1 to N....find which nos are repeated in the array
-Given pointers to two nodes in a binary tree....find their least common ancestor...each node has pointer to only the parent node...not the left and right child..
-In a binary tree(Not necessarily a BST)...suppose the weight of any node is defined as the product of the key value of the node and the level of the node(Root at level 1)...find the node with maximum weight in the binary tree
-A sorted array of size n is right circularly rotated k times and this rotated array is given to you as input...Find out the value of k in log n time .
-There are some processes running at time T....and there are processes running at time T+30.
You have to find out
1)Which processes died at time T+30,which were alive at time T
2)Which are the new processes at time T+30,which were not there at time T
3)Which are the processes that were there at time T and are still running at time T+30
What data structure will you use to represent the process lists and write code to find out the answers to the 3 questions above
-Given a binary search tree...and a target sum...starting at the root...which all paths add up to the target sum?...if there are multiple paths....return the path with least no. of nodes.

Interview Preparation Tips
Experience: The interviewer asked questions based upon CV. He first made me adjust to the environment and then started the serious questions realted to technical stuff.
Tips: Never lie about any subject you don't really know. Keep a particular topic strong, in my case it was Database Management. Have good problem solving skills, if not efficient but at least a good solution.
Round: Technical Interview
Experience: The round consisted of technical questions based on my analysis of the first round. Consisted of higher levele questions related to my topics of my expertise.
Tips: Be ready for any spontaneous questions. Explain whatever comes to your mind instead of quietly thinking. Be communicative and confident. They don't care about the syntax but rather the logical thinking.
Round: HR Interview
Experience: Just be communicative. Since you've qualified till the HR interview, you are almost confirmed for their position. They checked if I could handle pressure or not. They tried to know if they could give me more responsibilities in the near future or not.
Tips: Be confident and don't hesitate to answer. Express what you feel genuinely. Show that you are a responsible guy.

I was interviewed in Dec 2016.
Interview Preparation Tips
Experience: For CSE and EE students , CPI was not at all seem to be a criteria for shortlisting and almost all who have a decent profile got shortlisted for the test. However, for other department students they shortlisted above 9 CPI students.
Round: Test
Experience: It was a 2 hour test. It consisted of 3 sections-Quant , Machine Learning and Computer Science . Each section had 10 questions and 45 minutes were allotted for each section.
Being from non-CSE background I attempted only 2 sections ie. Quant and Machine Learning. Machine Learning section was fairly easy this time and almost all questions were standard. If someone has done an introductory course on Machine Learning and basic stats , this section was a cake walk for him. However , attempting quant section required some preparation of solving probability puzzles (computing expectations etc.) ,basic linear algebra and geometry base questions.
Duration: 2 hours
Round: Technical Interview
Experience: I had 2 rounds of interview. Both were technical ones.
In the first interview , they asked some probability puzzles (from 50 challenging problems in probability book) . Since I had completed that book before , I was able to solve them . Then they asked 1-2 algorithm based questions like formulate an efficient algorithm for solving a particular problem. I was not able to solve them completely but tried to give them the overview of y approach. The interviewer didn't seem to be satisfied though. It lasted for around 20-25 minutes.He told me to wait outside . To my surprise, I was called for the 2nd round.
The second went better than the first round. They again asked questions on computing probability , expectations , constructing a Markov Chain for a a given problem etc. Since I had done 1 course in Fiance also , he asked me questions from it also which were quite easy. Then he began asking algorithms and asked me to explain a sorting algorithm and I chose Quick Sort. While explaining it , I got struck at one point but the interviewer was helping me by giving hints and I was able to explain it fully. The second round was quite exhaustive as it went on for around 45-60 minutes.

Interview Questionnaire
4 Questions
- Q1. Asked about my projects – the technical aspects, scope, etc
- Q2. Databases and Mysql – queries, types of keys, joins, etc
- Q3. Fundamentals of Operating Systems – threads/processes, scheduling algorithms, memory/storage, etc
- Q4. Data Structures and Files, so – sorting/searching algorithms, their complexities, files, other data structures, etc
Interview Preparation Tips
Experience: The first round, quite naturally, was the aptitude round. We had to answer questions that were designed to test our quantitative and technical abilities. But this was only the first part. The second part involved finding computational solutions to simulated situations. These questions needed to be solved in a programming language we were asked to choose earlier, during the aforementioned first part. I chose to do it in Java as that is one language I am really thorough with. I understand that C/C++ are more important and versatile, but what matters here is your inherent understanding of the concepts involved
Round: Group Activity
Experience: We had to build model buildings, using LEGO blocks. Other than the fact that I love building things from other smaller things, the supplied material took me back to my childhood days. We were divided into four groups. Two in each room, and each group consisted of 8-10 candidates. We were given a time limit within which we had to design and construct a building. As a surprise, after half time, they asked the two groups in each room to merge their projects. This probably was to see if the candidates were pro-active team players, and could handle unexpected situations like professionals.
Round: Technical Interview
Experience: There was another technical interview after the group activity. I was interviewed by two of their officers, who again asked questions similar to those from the first technical round. It went quite well, since I was quite confident about the way I was solving the problems they gave me. Thinking out loud is key, as that lets them in your problem-solving abilities. That way, they let you know if you are headed in the right direction. My interviewers were quite pleasant, as they liked discussing possible scenarios to the problems they gave me.
Round: HR Interview
Experience: there was an HR round, where the woman interviewed me about my projects. She needed to know if I had the guts to finish whatever it is that I started. So she asked more on the lines on my role in the projects I had undertaken in the previous years. She also asked me about my working experience from before. That too went well. It was pretty much a standard HR interview – projects, hobbies, traits, etc.
Round: fitness roound
Experience: There was another round in the end, which was to test the candidate’s professional fitness – if they indeed are the right people for the job. I found it to be a blend of technical and HR interviews, more on the lines of HR though. All in all, it was a brilliant experience
General Tips: To my juniors, study hard, be sincere, be yourself, be smart (preferably in that order, but you are free to improvise!)
