Here's my interview feedback:

First, just enjoy yourself, and present your honest self. You can sell yourself during the interview, because it's closed file. Then they sit down and discuss your interview with your application in hand. They give you two scores: one solely on interview, the other with your application.
It's really important to understand and to be able to clearly spell out why you want to go into medicine. Don't be afraid to tie in aspects of your personal statement (they haven't seen it yet); especially be able to tie in activities that you enjoy, or other random things that define you. Example: I'm really involved in music, and was in the Boy Scouts. For open ended questions, I looked for times that I could 'easily' tie back into things that define me and I love. (But don't make too much of an effort because it will be obvious you're trying too hard.) The interviewers ran with my information as well. Example, they asked like "How would being in the Boy Scouts help you deal with those that don't want to follow your leadership?" or "What aspects of music do you see helping you in medicine?"
So, if you're able, turn it into a discussion. Go beyond their question; offer them additional information about yourself. Don't take the conversation "ball" and toss it right back - hold onto it for a bit. It really allows them to dig deeper into "you" and ask more personal questions. From what I could tell, the interviewers are asking questions to try to understand some major "character" points, ie, leadership, committment, etc.
Overall, the day is amazingly stress free. The lunch is amazing! Students are first class. Don't be nervous about anything. Just be confident in yourself... you (and we all) have come a long way from when we first dreamt of medicine. For me, I wasn't nervous at all, I was very excitied (not nervously, though) because this is the last major step to beginning the next stage of your life.
Best of luck
