Hi! I interviewed mid-October and this is how my interview went.
There's breakfast first thing in the morning, then you'll have a chat with Dean Wofsy. He was so awesome, and funny, and was a super warm and welcoming person. Then, we were given our folders and our schedule for the day. Then, we were brought down to a student lounge and met a few med students who took us to their classes. After that, we went to lunch with a few more med students. Afterwards, we did our tour of the campus (led by even more med students!). Then, it was the interviews. You'll have two interviews - one with a faculty, then another with either faculty, staff or a student. Your interviews might be all over the place too, so you might need to take a shuttle to get to your interviewer's office. The admissions staff will give you maps and times for the shuttles so you shouldn't have any issues with finding the places. You're also given the contact info of your interviewers so if you're running late (shuttle came late or something) you can contact them and let them know what's up. This happened to one person in my interview group and the interviewer was very understanding. Then after that, you're done for the day!
Tip: Just enjoy the day! I loved the vibe of my interview group and everyone was really chatty and friendly and outgoing so it def set the tone for the day. And all the students, staff and faculty you'll meet are very friendly and helpful! They really just want to get to know you and see who you are as a person, so just relax and be yourself!
