Sorry, I've been slow on the interview response lately.
This will likely be the most chill interview you have so don't worry. Dean Peterson goes around the interviewees and has everyone mention something intersting/random about themselves. They feed you frequently which is nice for me since I've been hungry at most of my interviews. It was one on one across the board. I'm not sure how many interviewers you will have. I interviewed MSTP, so I had something ridiculous like 4 interviews. However, they were all friendly and had all read my file carefully. My student interviewer was also the most challenging, but must have given me a good review because I was given a slot. He also gave me some good advice about how to handle some problems we have had with anesthesia in our animal model (very useful).
This was also the school who made the best impression on me at the interview. It doesn't feel like its in the middle of orange country strip-mall hell (which it is). The campus is much more open than I expected with better housing and parking than other UC schools. If you want to you can live in Newport. My little sis has an unbelievable place by the water and she is just a wee undergrad.
bty, I do not recommend staying at the Travelodge recommended by the medical school. The shower flooded and I was allergic to something in the place. In the morning I couldn't figure out what was wrong with my vision when I woke up. A quick look in the mirror confirmed -my eyes were nearly swollen shut! 😱
