Round: Test
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!)
College Name: IIT MADRAS

Round: Test
Experience: There was negative marking for these questions (+4 & -1) and the number of questions in the second section were more (10 and 20 respectively, I think).The second part of the test was a Coding Round, online. We were given 3 problem statements to be solved in 45 minutes and the programming languages allowed were C, C++ and Java. However you are required to use the same language for Part 1 (Technical Skills) and Part 2 (Coding Round). So make sure you know any one language in its entirety. I hadn’t touched anything apart from C. The questions were essentially based on data structures.
Tips: Word of caution: Be wise in designing your strategy to solve questions, there always IS a sectional cut off and the competition is cutthroat.

Round: Technical Interview
Experience: -1 was pretty much basic, probably just for them to find out whether you know everything that you claim to know. I was asked questions on the basics of C, Data structure implementation, DBMS AND OS. Sounds daunting, but it really wasn't. My panellists were really cool about giving me all the time in the world to think about my answers, they'd even roll their chairs to the corner of the room and chit chat when I'd ask them to stop looking at me. Not a recommended course of action for you guys, because you might get really badass panellists who might want to take a stress interview and using this would probably get you a ticket to take you directly out of the building. But the point is that you don't need to panic when you're asked a question that you don't understand AT ALL. It is probably just a coating of shiny silver on a very basic problem. ALWAYS remember to restate the question as you understood it to make sure that you're on the right track. If you're right you get a bonus for being able to analyse well. If you're not, they will make you understand and you won't spend 15 minutes of your interview time solving a misinterpreted question.

Round: Group Activity
Experience: This is subject to change every year, but for ours we had the one with the Lego toys

Round: Technical Interview
Experience: This round was perhaps the most difficult of all, with gruelling technical questions that I couldn't make head or tail out of. But they were satisfied with a broad outlook to the number of solutions and the different ways to approach the problem. They asked me a little about how my day had been till then and for improvisations on the answers to the questions I was asked in the previous rounds. I was also asked a question about synchronization that I answered with my knowledge of embedded systems. They were really interested in how I applied unrelated knowledge to solve a problem that I would otherwise not be able to answer. This was the end of TECH-2 which made me believe that I had screwed up entirely and that I was out for sure.

Round: PRO FIT ROUND
Experience: I went in to my ProFit round with an "I-should-really-have the-best-time-with-this-thing-since-it-is-all-down-the-drain-anyway" attitude, but really, I think that is just what you're expected to do anyway. :) This ended up being the coolest round of all and I had the time of my life for those 30 minutes. My interviewer asked me ALL the general questions you expect in an HR, and I answered them all very, very truthfully and with really long explanations :P The guy was a veeeeery keen listener and caught on to each and every one of my indications. He let me talk about practically everything, from my very hippie-like outlook of life to the most silly bets I have placed, ever. And the best part was that he was always interested, poker-face like, but always waiting patiently for more exemplifications. Don't bother trying to make up achievements you haven't really made, because they don't care about how accomplished you are, more like how zestful you are, and it probably shows when you're talking about things that you love. Long story short, talk your heart out, they hardly speak in all of those 30 minutes. Let them know that you really ARE passionate about the things that you do.

Round: HR Interview
Experience: The next round that I was immediately ushered into was my HR. Now, I probably felt what I did because I had talked a LOT in my previous round, but I really thought this round was predominantly precursory. My interviewer was one of the big shots of the day, but he hardly asked me any questions that could qualify as HR. This person was the only one from all of my interviews who was even remotely rigid, but that too only marginally. He was ultra-friendly again by the end of the interview. This might vary case by case, but he only asked me things like my comfort with relocation and what I aimed to achieve in the next 5 years. At the end of the interview, he kid around a little and escorted me to the waiting room.

Round: Technical Interview
Experience: number of interviews were 2 where the 2nd was more of a confirmation that I am willing to work with them.
I answered most of the questions they asked except who is teaching you corporate finance. I asked a lot of questions about what they do and what is their view about Indian accounting laws
I think they are looking for knowledge in finance and less of globe during the interview.

College Name: IIT Madras

Round: Technical Interview
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.
