Applied through campus recruiting and was called in for a 45-minute on-campus interview. The interview started out with some standard questions about my background and interest in consulting. The interviewer also asked a couple of questions specifically about issues facing the pharma/biotech industry, which was unique among the boutique firms that I interviewed with. There was also a case, which was fairly straightforward - a market size estimation for a new drug, if I remember correctly. I thought that most phases of the interview went fine, but didn't feel a great vibe with the interviewer, who struck me as kind of cocky (though nice enough). Sure enough, I got a rejection notice a few days later.
