Round: HR Interview
Experience: They had 4 interviews.
McK1: Have faint recollections. However I remember I did well on the case and had loadsa HR involved specially in my work on internships and research paper.

Round: Technical Interview
Experience: McK2: The interviewer was a PhD in Chem Engg from Stanford followed by an MBA from Harvard. I found this before going in and got real nervous. He started off with some Chemical Engg questions and soon realized it was no use! (He did even comment that I had not learnt anything in Chem engg in the 4 years). We then moved on a case of petrochemical industry where a new player wanted to enter an oversaturated market. I concluded that scale is important and the entry has to be below the existing market price. Some HR including my question to him. Had a long discussion on Foreign MBA vs Indian MBA. At the end of the interview, I guess I had done a good enough job (surprisingly after the start I had) and was called in for the next 2 interviews..

Round: Case Study Interview
Experience: McK3: This was a disaster! And a big one. I was given an extremely easy case on nuclear reactor vs coal reactor economics. Simple mathematics which I screwed up because of just 1 simple error. I realized the same pretty late and pointed it out. He said it was ok. No HR

Round: Other Interview
Experience: McK4: The whole interview was a discussion on my BTP and seminar. BTP was related to Phosphoric Acid production. The discussion revolved around whether phosphoric acid should be produced in India or whether we should produce it outside from where we import ore. Then we moved on to my seminar which was related to Kyoto Protocol. Finally I asked question on how different is a foreign MBA vis a vis an Indian one. Very peaceful and fun interview!
Tips: The single biggest mistake I committed was going in a haste into the McK 3rd interview. I got involved in some placement work between the interviews and forgot to carry my folder or even a pen. This is probably why I did not do well on the case (which was probably the easiest of all 8). Its very important that you take 5 minutes off before walking in, get your composure and stop worrying about other things and just attend to the interview on hand. Key learnings included the fact that it is relatively difficult to come back if you don't start well. Thus its is better to take something like 5 seconds before you answer the first 2-3 questions to recollect thoughts, organize them and frame them well. Also that you need to be comfortable with everything on your resume. I appeared for 8 interviews and never mentioned/was asked anything related to MI which I thought was the most important point on my resume. Instead I was questioned on my hobbies. Smallest points on the resume could be the ones you are grilled most on. Another very important thing about case interviews is the fact that the interviewer will be guiding you all through to the final solution. Any thing that he speaks should be heard and taken notice of. Most of the times there will be a small hint given at some point and all you need to do is catch on to it! Structuring your answers is extremely important. One more important thing to keep in mind is that all your answers should kind of show to the company that you can FIT into the company, the job and the culture. It is also important you walk in with the feeling that you can get the job. Specifically in cases, if you get stuck, take some time off to think. Structure your solution well, it carries the maximum weight.

General Tips: Firstly suit up only in case you are comfortable in it. It makes no sense to wear it and be uncomfortable throughout. And in my opinion even if you do not wear one, it never goes against you (at least consulting). For companies like FMCG/Tech its better not to suit up because it doesn't go with the company cultures. If its IBanking, it is good if you wear one. It is very important that you have some questions for the interviewer for any given company. And it is more important that the questions are intelligent and genuine. Attending PPT/ reading up website is a must for the same. Most importantly you should not talk to any other candidate on interview experience before your interview. The interview changes for every candidate. If say for example you hear the case beforehand, the company is bound to find out which would ruin your chances for sure. Further talking to people who have already appeared increases the nervousness. Posture is something that you have to take care of. People have a tendency to relax which should not be the case. You should seem eager for both the interview and the job. While answering any question the most important things to keep in mind are • Take 5 seconds off before venturing into any answer. Compose your thoughts real well. Then start. Its better to get the whole thing in a impactful way then to miss out on certain points. It also doubles up as giving the interview a feel that you are thinking before answering.

Round: Interview
Experience: There were four interviews, with a case study and some HR questions in each. 
The first interviewer was an IIT Delhi alumnus and asked me a case on whether a telecom company should go for exploring the 3G license option. He provided me with information as and when I asked for it. Later during the interview, I asked him about his experience with McKinsey. 
The second interview involved a case on acquiring land for a B-School. The case was mainly qualitative and the HR questions were also straightforward. Giving a thought to goals and aspirations helped. 
My third interview was with a partner. Again, standard PI questions: something about yourself, why consulting, what if not McKinsey, important attributes of a good leader, why should we hire you etc. The case was on the design on entry and exit gates for Delhi Metro. 
My final interview was again with a partner and there was no HR part. It started with a case, and then there was nothing else to discuss. Anything and everything that could possibly go wrong did. I did badly in the case and towards the end made errors with simple calculations as well.
Tips: It is important to think on your feet even if you are not able to make much headway with the case. This case had sealed my fate.

General Tips: Most of the times, things go on as they are supposed to, we do what we are assigned, meet deadlines and get it over with. Knowing what to do after four or five years of study at IIT is one of those deciding phases where we have to do something out of routine, think about what we actually want, what we can get from where we are. 
Here is an account of how I went about making my decisions and preparing for it. In one of those routine placement talks, a speaker remarked, ‘there are two ways you can choose a career- by extrapolation from what you have right now and by interpolation from your long term goal’. This helps one realize the importance of identification of long term goal. In my opinion, once a person is convinced about that, it is easy to pull off an interview; more importantly, it is easy to identify which options to prepare for. 
I’d eliminated higher studies at around the middle of fourth year and was convinced to sit for McKinsey and core companies. Resume preparation began at around August with the master resume followed by a resume for core electrical companies which come to campus. Later I made a one page resume for McKinsey. Preparing for McKinsey helped a great deal in preparing for the HR section of the interviews. After McKinsey results, I revised the electrical courses required for the companies which were coming to the campus.
The first day was hectic with a whole lot of companies lined up. One had to be prepared for
all the companies because the shortlist came just the night earlier.
