That point in the interview is your opportunity to interview the school. Dental school is a major investment, both in terms of money as well as personal/professional growth. What are you looking for in a program? - Ask them questions that haven't been answered in their presentation. What is the clinical situation like? I think that a lot of applicants forget that the interview is just as much about the school checking the applicant out as it is the applicant examining the school. Remember, you are going to be at that place for four, long years and buyers remorse is terrible. Do your homework and leverage such time in the interview to gain information necessary for a well-informed decision.
