If you have two interviewers and the first one answered you questions, ask again; another perspective is always helpful. If you have no questions, you could be viewed as being uninterested in the institution. Medical schools want to accept applicants who want to be there and are enthusiastic about their program and institution.
This is your opportunity to learn more about the medical school in order to help you decide whether or not it is the right “fit” for you. Can you see yourself there? Would you be happy there if accepted? Does the school offer the social and academic experiences that you are looking for in you medical education? If you are curious about clinical experiences, the curriculum, or what type of academic support services they offer to students, this is the perfect opportunity to find out more!
Do not, however, pepper your interviewers with questions that could easily be answered by viewing the school’s Web site or from the materials that you have received. Your questions need to be genuine and should come naturally out the conversation.
