The interview is your opportunity to discuss your personal history and motivation for pursuing a career in dentistry as well as any aspect of your application that merits emphasis or explanation.
One of the keys to a successful interview is to approach the interview from the perspective of the interviewer. As they speak to you, interviewers will ask themselves questions like “Do I like this person,” “Is he/she a good fit for this school,” and “Can I see myself teaching him/her at a dental school, consulting with him/her as a colleague, or referring family members to him/her as a patient?” Stress interviews are the rare exception, not the rule. It is much more likely that your interview will be relaxed and conversational. The idea is not to worry but to prepare.
