"I have less than a 3.6 undergrad (slightly) and a 34 MCAT, very non-traditional volunteer activities and only about 250-300 hours in the hospital setting."
I have the same MCAT, a slightly higher GPA, and I'm "non-traditional" in the sense that I'm taking 1 year off. But you beat me in the # of hours in the hospital setting. I have, however, done some intersting research and learned quite a bit from it. Also, I think my faculty interview went quite well, though my student interview was nothing special (not very good, not very bad-- almost a textbook interview, a Q&A session).
I was wondering, though, if your interviewer(s) gave you any indication that the school would think highly of you. My faculty interviewer complimented me on several occasions, but something about the way he said what he did makes me wonder if he was being sincere or not. What if he says that to all his interviewees? I'm being paranoid, I know, but as I said, I am obsessing about this school.
What surprised me, though, was that I got an interview at all. In fact, I received an invitation for an interview only 3 weeks after sending in my secondary just after Thanksgiving. My answers to the secondary questions, I felt, were bad, terrible even, and while I did get the interview, I'm afraid that those answers might come back to haunt me now that my hopes are so very high.
Also, do you know if the faculty interview at USC is weighted much more than the student one? I was told by a UCLA med student (who interviews applicants) that student interviews there are just as important as the faculty ones.
