After on-campus networking sessions, the next step was to apply via my campus career center for an on-campus interview. The first round, they interviewed around 100 candidates on-campus, with a relatively small fraction moving onto second-rounds at each native office. The first-round consisted of two 45-minute interviews, with about 10-15 minutes of fit and a case for each. The second round was a similar format at the BCG office in my city of choice, but the cases were generally more involved, with the case given to me by the Partner being significantly more challenging and quantitative.
