1. interviews are later on in the afternoon. much of the morning is like orientation/Q&A
2. same questions - usually about why you want to be a doctor and your specific activities (research, shadowing, volunteering), occasional health care questions...
3. Yes open file though I don't think they know your scores. It seemed like both of them assumed I had much higher scores than I did which was a bit nerve-wracking...
4. No they don't tell you who your interviewers are. And even if they did, it would be pretty freaky for you to google them beforehand and pretty stupid to try to "tailor" your responses to what you think your individual interviewers might want to hear. There was a bunch of residency stuff/photos that they ask you to bring if you're a cali resident
5. Chill, don't talk yourself up or down too much. Be honest, humble, and excited about California/UCI. And remember, if you get in, then wonderful...if you don't, then it's not because you are unqualified...you simply might not "match" the school.
