Interview Preparation Tips
Round: Resume Shortlist
Experience: Fundae session by seniors and a resume workshop by some company. Also, sent resume to some seniors for their opinions and I think this was an important part of it.
Tips: I suggest Pre-placement talks, are a must. What is more important is not to believe the PPTs completely and ask seniors about the level of fundaes (finance/tech/otherwise) and preparation required to crack the company. There is a lot of good material on ATKEARNEY and other website. Other than that I used the material available for years.
Round: Interview
Experience: Final offers in my division were 12. There were two levels of case interviews. The first interview was to judge if I would be suitable for the Strategy and Operations profile or for the Technology and Integration profile. There were two interviewers. They explained to me both the profiles and asked me what I wanted to choose and why. Then asked me some general HR questions like why consulting, why you etc. Then started off with an informal case study. It was about a new company which wanted to start a new low cost airline and had no experience in this market till now. It has two options: either to acquire an existing company or to build up all processes on their own. I was first asked to qualitatively mention what all aspects I would consider. After that they asked me what new things could this company do. They were pretty satisfied with my answers and I was confident of getting listed in the next round. In the next round there was single interviewer who was looking quite senior. Asked some HR questions. One case study about a consumer durables dealer which was again qualitative. Asked some HR questions that's it.
General Tips: Lack of interaction with seniors throughout IIT stay was one thing for which I had to pay. I had no seniors in my wing and I had no fundae of the amount of preparation required.
So make sure that you have certain information.
