Just had mine yesterday. Super cool and laid back day. My interview was at 2 PM, so I didn't have to get there till 10:40 AM when the tour started. You meet up in the admissions office and chill with all the other interviewees. Some MS1's came into answer questions and there was a short presentation on the curriculum by the dean. Then you tour, and at the end of the tour you go to lunch with current med students. It was like 4 interviewees for 1 med student, so it's easy to get all your questions answered.
Lunch was done by around 12:50 and then you go back to the admissions office and there was a small financial aid presentation. After that you chill there until your interviewer comes and gets you. Some people had to go to a separate part of the campus though and they were given directions by the office. My interviewer was super cool and it was very laid back and conversational. PM me if you have any other questions!
