If you receive an interview, that means that you are mostly qualified on paper. The purpose of the interview is to determine if you are personable and will be a good fit for that particular dental school. During your interview, tie in your extracurricular activities, volunteer experiences, shadowing experiences, and leadership positions to show them that you are the applicant that they want in their school.
During the interview you are also “interviewing” the school. Be sure to have prepared questions about the school beforehand because they will ask you if you have any questions. Some possible questions include the following: Do they schedule time to prepare for boards step one? How have past students done on their boards? Am I able to go on away rotations during the clinical years? How do I find out about military scholarships? Do they use a point or procedure based clinical system? Also, try to convince each school that this is the school you would love to attend.
Most importantly, be yourself! Relax! Talk through your answers with someone before you interview. Below is a PDF of practice interview questions. Go through the questions to prepare yourself for the interview.
