The entire process was very smooth. I interviewed on campus in October and received an invitation to interview on-site a couple of days after. I signed up for an interview date that was around 3 weeks away. I interviewed from 8 AM to 1 PM on the first Friday of November and received a phone call with an offer at 2 PM on the Monday after. All questions were case questions, no behavioral ones. The on-site interview had 3 interviews total, all of which were cases. 2 were typical case questions where the interviewer laid out the background and context of the problem and you worked through the questions together. The third case was a "product interview," which was more of a creative conversation rather than an interview. The interviewer asks about your thoughts on a particular situation and I just spoke my mind.
