In-state re-applicant...just got invited to interview! First available date was Monday, October 8th. Stats: ~3.75/33.
NCMED, I interviewed at UNC last year and didn't have the best experience, but that was largely because I over-prepared. During the first interview, if my answers deviated from the "script" I had practiced I began to think I was doing poorly. I ended up nervous and not performing as well as I should have. Not to mention, my first interviewer really grilled me on my leadership skills, which I wasn't very well prepared to answer. That said, my second interview was really laid back and enjoyable, as were most of the interviews I heard about that day.
My advice; relax. 🙂 Have a general idea of what you want to say for the most commonly answered questions, but don't over-prepare like I did. And if your interviewer asks you a strange question (UNC examples I've heard include "if you were a vegetable what would you be?" and "what are three items that are always in your refrigerator?"), just find the humor in it and answer as best you can! You'll do fine!
One other thing to note...UNC is very friendly to re-applicants (from what I understand). If for some reason you don't do as well as you could have, you'll get another shot next year if you'd like! Good luck!
