I had my first (and second) interviews last week as well. My first was my top choice, and little bumpier then I would have hoped for. I was feeling confident most of the morning, but then got really, really nervous right before the actual interview began. My interviewers asked tough questions, but didn't grill me too much and were incredibly nice. Never the less, I felt like I rambled way too much, and it wasn't the stellar performance that I probably needed for that school. It will probably be a few weeks before I hear anything, they wouldn't tell me when I could expect an answer. No clue what the outcome will be, though I feel it will probably be a rejection. Holding out the tiniest amount of hope...
My second interview though was an MMI, which I found more fun, and much less stressful (probably because I already had one interview under my belt). Some of my interviewers seemed more nervous than me, which really put me at ease. Feeling pretty sure that I did well, which was a nice boost of confidence, and hopefully I'll hear back sometime this week.
I thought waiting for my MCAT was hard, then interviews, but waiting for this post-interview stuff is terrible.
