I interviewed for McK as APD candidate. The recruiting process is really intense and competitive and unfortunately it's not true that if you "pass the bar" they'll hire you (as they keep repeating at recruiting events). 1st Round: written test (26 questions in 1hr) + 2 group case interviews 2nd Round: 2 or 3 case interviews + personal experience interview with Engagement Managers --- be sure to practice many cases McK style: in this round even if you do a small minor mistake you'll pass (I did), as long as you show confidence and good analytical skills. The good thing about 1st and 2nd round is that you are competing against other PhDs, who have more or less the same skill set, so it's a fair game. I was called ~ a week later and told that I passed. My final round was scheduled 2 days later that call. 3rd Round: three 1:1 interviews with Associate Principals and Partners and 1 case group interview (thankfully, this kind of interview is not done in every office) --- case interviews with AP/Partners are basically the same, the group interview is different from round 1: you are given slides and expected to solve the case with the other candidates for 30 minutes. Partners are in the room and will observe you the whole time. After 30 min, they'll act as your client and you'll have to present them your findings. I was told to be collaborative and be myself during this role play: however, my impression was that the most aggressive and arrogant candidates (who would not shut up for a second to hear your opinions) were the ones considered successful. Also, the other candidates might be MBAs as well, so I let you judge if that's a fair assessment. I was called the same night and told that I was not offered a position. Reasons: I had great presence and everybody enjoyed meeting me BUT during the case I was a bit slow in answering a question and I didn't fully address it according to my interviewer. In reality, I really felt as if my interviewer was trying to come up with excuses since I asked a clarifying question and it took me probably 30 seconds to understand what he was asking me and fully answer it (I remember him saying "great" after I was done talking). Also, my interviewer didn't know the feedback from the other AP/Partners so I wonder how they discuss the candidate performance if they don't share these details. At the end of the day I felt I wasted my time, the recruiting process is not as transparent as McK claims it to be. The main reason why I think I was not hired is because I am not aggressive and arrogant enough for McK and honestly, already having an equally good job offer, I am happy this way.
