To give a jump start (a bit harsh, A. Caveman, no?):
There is a great <a href="http://interviewfeedback.com/" target="_blank">interview feedback</a> website which lists the kinds of questions one encounters at a particular school, plus so, so much more.
Also, in general be prepared for (courtesy Eric Wilkinson, M.D.):
- The favorite -- Tell me about yourself.
- Where do you see yourself in 10 years? (often asked)
- What does your family think about this?
- What is the biggest problem facing medicine today?
- What are the disadvantages/downsides of a career in medicine, besides no time?
- What are you looking for in a medical school?
- What do you think about "insert current hot topic here"? (HMO, PPO, Doctor-assisted suicide, ethical/moral issues of cloning, other financial issues in health care delivery)
- What field of medicine are you interested in?
- What do you like to do that isn't science related?
- What will you do if you do not get accepted somewhere this year?
- What are your strengths/weaknesses?
- And, perhaps the most popular...
"Why do you want to be a doctor?"
