5 Interview Rounds
Interview Preparation Tips
Round: Resume Shortlist
Experience: CGPA about 8.00
Tips: Criterion for getting shortlisted for test - CGPA > 8.0
for GD - the score in their test
There was no shortlist after GD (all were called for PI) but they were looking to eliminate those who talked about technology and research instead.
Round: Test
Experience: There was a simple test on English and basic level Math. A timed test (no calculators allowed). CAT preparation can help but not exactly necessary.
Round: Group Discussion
Experience: The profile is all about teamwork and hence GD was an important part of the selection procedure. The panelist, then, tried to confuse us by citing examples of advanced technology and research in the context of "smarter planet". He was actually looking for people who talked about "ideas for business expansions" and not about "knowledge of advanced technology".
Round: Interview
Experience: There was just one round of HR interview. Predominantly resume based. The interviewer just had a chat with me, asked about my hometown, discussed a few extra curriculars I had mentioned in my resume. There was this one common question about teamwork. He asked for my experiences of teamwork and what I had learned from them. I think he was also looking for communication skills.
General Tips: 1. 9.66 CGPA in Management minor stream, overall CGPA > 8.0
2. Internship at IMaCS where I worked in teams with MBA grads
1st and 2nd years - explore all branches, all fields, as much as possible. Maintain good CG. Have some extra curriculars.
2nd years - get your passport asap. do a core intern to get an idea of your field and also to fill your resume.
3rd years - decide whether or not you want to app. (I converted to dual degree because I was still indecisive on this).
If your CG is low and you are bent on apping, do some extra projects, put papers and maintain relation with profs.
Skill Tips: I did not particularly prepare for non-core. I just solved a couple of quant papers. I did not particularly prepare for core companies. I did observe that going through structures and geotech courses really helped my classmates land core jobs.

5 Interview Rounds
Interview Preparation Tips
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.)
