Don't stress about this for a minute. The interview questions are obviously very important, but at least in my case, they were presented in such a way that you could not be anything but yourself. The interview was conversational, almost disarming. Great day overall, it will probably move Penn State up on your list.

Interview questions they asked
Tell me about how you've come to be interested in a medical career. Why would you not pursue a degree in clinical psychology with your background? Why did you take the MCAT so late (non-traditional applicant) and what did you do between graduation and the test?
