College Name: NIT SURATHKAL
I was interviewed in Dec 2016.
Interview Preparation Tips
Experience: On-site interview (5 hours).
4 back-to-back 45-minute coding interviews, followed by a design interview, with a lunch break with a Googler in the middle.
The first coding interview was a set of (surprisingly) trivial (no algorithms needed) incremental coding questions.
The two next coding interviews were problems straight from the "Cracking the coding interview" book. Even though I divulged that I'd solved pretty much exactly the same problem before, they didn't give me an alternative problem and I quickly coded up a general and optimal solution for the problems. Follow-up in-depth questions were minimal and not hard.
The last coding question was a pure algorithm question related to search trees/tries. No coding required, spent the whole time reasoning about the most effective algorithm. This was a bit of a brain twister.
The design question was related to high-level system design (not OO design) for storage and search in geographic data. Focus was effective search as well as scalability both in traffic and data volumes.
Tips: Read "Cracking the coding interview" or other similar literature. Solve all the problems and you should be good to go. If you solve a bunch of problems at HackerRank (or similar) as well, you'll have the added bonus of training on how to generalize the algorithms.

Interview Preparation Tips
Experience: On 1st September 2016, Cognizant held this round at our college. We were initially told that it would be an adaptive paper but it was not so. We could not navigate between questions (both intra and inter section). There was a minimum number of questions which had to be attempted from each section else we would disqualify. The questions were easy and I found many questions common from AMCAT papers.
Tips: Practice as much as you can. Try to learn shortcut tricks to solve the questions quickly and easily. Try to solve questions within certain time limit. Give online tests so that you are familiar with giving tests on machine. Do not waste time in a particular question. If you can't solve it then leave it( if there is negative marking) or answer randomly( if there is no negative marking).
Duration: 55 mins minutes
Total Questions: 55
Round: Technical Interview
Experience: The interviewer asked me to introduce myself. I was nervous and so i fumbled in 2 or 3 sentences but then i took the pace. he chit chatted with me to release my pressure . he went through my resume and my marksheets. he asked a few HR questions and then started the technical interview. He asked me questions regarding microprocessors and electronics but I had prepared software subjects I being a CS student could not remember most of it. But I sill answered them with best of my knowledge. i told him that I would rather be comfortable with CS core subjects. then he shifted his focus to DBMS and Software Engineering I did not lose my calm although I was very nervous. I thought I would be rejected but finally I got selected.
Tips: Don't be nervous as most of the interviewers are really friendly and they give ample chances to prove yourself. Try to practice the your introduction. They may ask your questions that are not from your domain but try to answer them with your presence of mind and previous knowledge. you may be nervous but don't show that on your face. Try to have basic concepts of your core subjects.
Round: HR Interview
Experience: It is the best round. You can voice your own views. The interviewers are mostly friendly and you seem to have a discussion with your friends.
If you manage to appear for this round most probably you will be selected.
Tips: Just be simple and be frank. Answer to the point and do not sound arrogant.
Skill Tips: Try to clear the aptitude and half of your job is done. For technical interview try to learn the basics of c,OOPS,DBMS. Try to know about the company .
Be calm .
All the best..!!
