I had my interview on campus on Tuesday. A word of advice: if you forget your tie, all the shops on Michigan Ave. open at 10 AM. With a 20 minute cab ride to campus, this leaves just enough time to make the morning info session on time...(on the plus side, I got a really nice tie)
Anyway, I highly recommend visitng Booth. The structure of the campus visit program brought Booth to life in a way that no amount of online research can do. All of the students during the program were extremely helpful, and were very honest in responding to questions - "I don't know, but I can get you in touch with someone who does." I highly appreciated this approach. They were also well prepared for all of the standard questions applicants typically ask (and then some) - so much so that I ran out of new questions to ask my interviewer at the end of the day. If there was one piece of feedback I'd give, it would be to schedule some quick bathroom breaks! I was fully engaged from the moment I stepped on campus to the moment I left.
As an aside, I'd like to mention that the difference between my experience at Wharton vs Booth was like night and day. At Wharton, there was zero direction given - if I hadn't spent some time in Huntsman as an undergrad, I'd be lost where to find the student lunch, where the class visit was, how to reach the Admissions office (good thing I knew about the elevators in Huntsman), etc since no one was there to assist. The class I sat in on was also dry, but I attribute that to the professor. Booth was the opposite - students willing to help everywhere, with a well-run agenda. The class I sat in on (same subject as at Wharton) was also better, also probably attributable to the professor (but a 3 hour class? That's rough).
My interviewer was also more personable at Booth, but that was probably luck of the draw. Besides the usual questions already detailed on this forum, he also asked me what qualities I looked for when I hired my team, which arose naturally from the conversation.
Overall, I left with a very positive impression of Booth. Good luck everyone!
