College Name: IIT MADRAS

Round: Resume Shortlist
Experience: I had sent my resume to the hiring group, Selection through telephonic interviews. I was interviewed by three different research groups  (once by each).
Tips: Factors in decreasing order of importance: CGPA each stage. Ability to explain your projects precisely. Ability to solve ''standard" logarithmic problems.  The way you think and put down your Answer is the most important. The final answer .s not so I important, and they prod you when you think out aloud anyway.

Round: Technical Interview
Experience: Almost- by default they ask about your previous projects/internships if they are relevant to the group. Ofher questions depend on the group you are interviewed by and your own profile, In my case it was machine learning, text mining etc. I was told about the research problem they were dealing with then and asked f or comments/suggestions/.inputs and a discussion followed.
Tips: Basically these are specialized Interviews so it's good to have sound knowledge of your domain (analytical and application skills are very much required).

Skill Tips: CGPA>9.0, 1f not (like me) relevant work done in the domain and in past internship.A recommendation from the professor is also a good add on.
College Name: IIT Madras

Round: Test
Experience: There was an apititude test basically in line with CAT pattern. It was conducted online for about 45 min duration. The questions were rather simple but each question was time bound (around 45 sec or so).
Tips: As such I did not have any structured study plan. I did refresh some of my basics in mechanics and analysis. I was more inclined to get a job in aerospace division. Read as per your interest.
Duration: 45 minutes

Round: Group Discussion
Experience: Initially, we are seated randomly in a circular manner and each one was given two minutes to describe the topic. It was followed by an tense debate where participants converged and diverged on different sets of issue. They were particularly looking for interpersonal skills and out of the box thinking.

Round: Interview
Experience: The interview was purely management type.More questions were thrown at team building, bio-data, why this company? , project, what you Can contribute for the firm?, where you see yourself in next 5 -10 years, ambitions, some amount of optimization tools and techniques, concluding remarks....Interpersonal skills and clarity in answering where mainly
IBM was a more relaxed interview, which basically dealt with management and interpersonal skills. Questions like “if one of our team mate is very stubborn, lazy, adamant, how will you tackle the situation” were asked.
Tips: College (B Tech) curricular activities, NTSC certificate, Math Olympiad certificate, all India quiz competition awards were noted and appreciated. That really was a booster. That helps in implanting an idea that you are not just blah blah blah.

Skill Tips: Be very sure about your mechanics, analysis and design. These three are the fundamentals.
I haven prepared for placements exclusively. Here were combined discussions. However, it really helps if you can revise and make your fundamentals were clear. The basic understanding should be there. An hour every day for two months will do the trick.
Be really choosy of the company you want to be in. Learn a lot more of the company and get an idea of what they are actually looking for. But still don’t freeze your mind to those realms alone.. Be open minded and cheerful. The first few questions will set the mood of the interview. If you are bale to crack that, then things will be really smooth. Really concentrate on your fundamentals, especially analysis and design.

Round: Resume Shortlist
Experience: CGPA above 8.

Round: Test
Experience: Simple quant questions, 2 sections, 20 - 30 min each. Calculators were not allowed.
Duration: 60 minutes

Round: Group Discussion
Experience: 11 members were part of the GD! They were under the impression that students from IITs are usually interested in technology, research and engineering. Your enthu/understanding of what a 'business consultant' does is what is tested in the GD. Just before the GD, they said that they would explain what they meant by "smarter planet". They
confused us by mentioning some technological innovations (like solar power, prosthetic limbs, artificial heart, brain, GPS, etc.) as examples of smarter planet. After the GD, they were able to simply separate those candidates who talked about business consulting from those candidates who got confused and talked about technology.
Duration: 30 minutes

Round: Interview
Experience: 1. The first 3 minutes was just a general talk about my hometown, junior college, etc. ( I think he was also from Andhra)

2. He went through my resume and asked me why I put certain points, like my BITSAT score in there. He also pointed out that there was nothing much regarding sports. I just made defending arguments.

3. He asked me about my teamwork, instances of good and bad teamwork, what I have learned from my experiences of teamwork in IIT. He said that the profile would need me to work in teams with IIM grads and asked me how I could manage.

General Tips: 3 things:1. I had 9.67 CGPA in Management minor and this added weight to my non-core side.2. I did an internship at IMaCS in infrastructure consulting. I was able to put pseud that I worked in teams with MBA grads during that internship and that we worked well. I think I also spoke well about my teamwork in class projects.3. During the GD, I gave a good example of business consulting (something regarding Maruthi Suzuki which I recalled from Marketing Management class). It gave them a strong opinion that I'm into business consulting.
Skill Tips: Practicing early in the semester would definitely help for any kind of placement.
Skills: quant, puzzle solving
College Name: IIT MADRAS
Motivation: I was apping, so I didn't prepare properly. However, I must suggest those who app, (not the ones who are bent on going abroad, but the ones like me, like cats on the wall) to attend all the placement tests and put proper fight during placements. I'm not saying that you should practice quant months earlier or mug up the finance material. (Its great if you can do that too, but I expect you'd be busy with GRE, TOEFL, etc.) I suggest you to finish (or pause) your SOPs and stuff before the third week of November and attend all the companies' tests and get placed early. A good placement is not only a big relief but it also allows you to drop your safe universities and apply to more strong. I didn't attend a couple of tests and regretted it during placements(getting placed on 16th day is not exactly Christmas) Never ever mention GRE or MS or any higher studies, for that matter, in any placement interview if you want to get placed in that company, no matter how friendly or understanding the interviewer might seem to be. (I got rejected in the first round itself in a couple of companies for doing this.)
