The interview is to see whether you are pleasant or not, if you can interact like a normal human being, and if you are convincing that the school is right for you without coming across as a jackass. I had 4 interviews: The 1st one I came across as a jackass, 2nd one I didn't know what I was talking about, 3rd was perfection, 4th I was so good that the school thought I wouldn't possibly choose them if accepted so I was rejected (for being so damn good). Be yourself; these interviewers are usually doctors themselves and can read minds. Also, if you have something to say, make sure you know what your talking about, otherwise don't say it, and don't be a jackass; naivety on your part will jump out and smack them in the face. If you haven't graduated medical school, there is nothing you can do or say to impress someone who has - don't try to impress anyone. Just prove that you are capable of getting along with people, that you can have the heart to stick to your goal.
