So many rounds of interview with the team and overall just very specialised and difficult. I interviewed for the Junior Analyst position with the DtV lab at McKinsey, and most of the interviews were done by members of the team. The topics were also engineering based and there was one specialised interview, the "teardown interview" where I had to look at a comparison of two product teardowns and make judgments as to how our company's "product" cost can be reduced.
