I've waited until I was several months in at the firm to write this, since I wanted to see what kind of prep they do once on the inside. Overall, it was a great experience. I had a 20 min intro call then moved onto one 45 min case before a final round of three or four 45 min cases and a 45 min behavioral. All of my calls were with Consultant peers, with the final at the Partner level. In contrast to some on this page, HR was awesome. I had a very busy two weeks at work during my final round and they were very accommodating in switching interview times and happy to spread the interviews out. Interviews started on time and I was told whom to expect. The people were great, it was a relaxed conversation which made it feel like something we were working on together. Behavioral questions were focused and it was clear that culture was something they cared deeply about (having been at A|S now for several months, this is definitely the case), and I had a whole interview devoted to this. As for the cases themselves, they were definitely rigorous and always involved some quantitative aspects with the usual concepts (market sizing, breakeven, etc.) but I enjoyed the qualitative strategy-type questions most. Interviewers did a good job of introducing and answering questions on the TMT lingo. The format was more Q&A than the stream-of-consciousness method at MBB; the interview would start with the prompt, then I’d do my framework, then the interviewer would say that’s great let’s explore X. Felt much more natural and closer to what an actual project is like here, where the team is given the whole picture and then assigned workstreams. I was called the day after my last interview by the Partner who interviewed me with an offer.
