Received interview offer after about 1 month. Did first round of interviews with managers and received outcome on same day and also received feedback on how I had performed. The first case was involved figuring out how a company could increase its profits. The second case was about determining whether a market was worth entering into. The second round of interviews was with partners. The first case was about determining whether a cost cutting initiative was worth it (focused on my numbers because I had made some errors in the first round, I had eventually corrected them but they do like you to get them right the first time before you share them). The second case was about understanding the revenue contributions of a company's product portfolio. All four interviews also had a behavioral component i.e. why Bain, why this particular office and what can you offer Bain. The first 3 interviews lasted 30-60 minutes. The last one was over in 15 minutes. The interviewers were all very pleasant and I got the impression that they all really wanted the candidates to do well. The cases were all pretty straightforward. I had to dig deep to get to the answers but there were no trick questions or scenarios. They are really just looking out for the following: - first, second and possibly third level structure - ability to prioritise - ability to communicate though process and assumptions - number crunching. Some interviewers were okay with rounding off, one wanted exact numbers to the second decimal. - likeability. Even the partners were pretty informal and it felt like a conversation amongst peers. The HR personnel were all pretty helpful too. I felt like I had my own personal cheer squad every step of the way.
