They'll bring you into a room and have you meet with at least one or two people. First you'll meet with the hiring manager and then an analyst or two. The people you'll meet with are always nice and friendly so it should go smoothly. Dress professional and try to be as personable as possible. They look for people who will take it seriously and will be outgoing since most of the higher level people couldn't care less about you.

It started with a conversation with the Execute Administrative Assistant from the Boston office. It was about 5 mins, she asked me about my GPA/SAT scores, if I had received a full time offer from my summer internship, and gave me a breakdown of the daily tasks (i.e. getting coffee for the partners, cleaning up, pitching in with daily tasks). For the NY office there are no analysts, so as an intern, you work with the partners. From the breakdown she gave me, it sounded like the internship is a glorified There is a modeling training session that you participate in every 1-2 weeks via webcam (its in the Boston office). She then asked if I had any questions, I said no, she answered all of my questions, and then she said she will get my information to the senior managers and get back to me. At this point, I withdrew my application from consideration. I do believe though it is followed up with an interview with the partners for the office you are considering. It's not really an internship from the way she described it, just underpaid help around the office.
