Applied off-campus for a summer internship from a part-time MBA program, but during the same timeline as the standard MBA internship recruiting cycle. They have several former part-time MBAs as consultants and had a nice process for us to get access to the firm. Apps were due in mid December and we got Interview invites in early-to-mid January. First round was in their Chicago office (part time students can't utilize on-campus intern recruiting--school rule) and consisted of 2 45-minute interviews. 1 was pure behavioral/fit and it was clear that he tried to ask questions that I may not have prepared for (slightly nonstandard questions), but he was super nice and the conversation was low-stress. The other was pure case and was standard in some ways, but this guy was more surly and also tried to present the case in a format that is a little different than the way most people prep for cases. They want to see how well you can go off script and adjust to a slight change in routine. They got me--I bombed the case and was only mediocre on the fit. One cool thing is they offered an optional practice interview the week before with a senior associate--this was helpful in the sense that it was additional practice with a little more pressure than just prep, but not helpful in the sense that the case was way easier than the one I got in the interview, so it kind of misrepresented the way I should be preparing.

Smooth interview process, very well organized. Two rounds with two interviews each (fit + case). Expect results to come 1 week after each round, with the possibility to get feedback from interviewers.
