Standard fit interview opening, but the interviewer introduced herself very quickly as being on her way out of the firm (working remotely) and very audibly lost interest after the first few minutes. Made for a pretty awkward situation, but after the normal barrage of fit questions did the consultant market sizing question (I believe it was estimating the market size for Crohn's disease). Did it in a weird way too, more like trying to force feed numbers rather than go through the actual thought process. Very robotic, but also really not interested in the sort of reasoning one is expected to demonstrate from that kind of question. Looking back, I believe it to be the rudest interview I ever had when applying to firms first out of school. The interviewer made no secret of her intention not to pass me to the next round and was frankly a little insulting in communicating it. Made taking the other job offer easy.
