Read over sample interview questions and brushed up on medical ethics.
What impressed you positively?
How enthusiatic the med students were about the school.
What impressed you negatively?
My interviewers were late getting to me.
What did you wish you had known ahead of time?
That I would be the last applicant to be interviewed.
What are your general comments?
Even if you think you did badly, you probably didn't. So try not to be so hard on yourself afterwards. The interviewers were friendly for the most part, even laughing at my attempted jokes.
