Know your application. If there are weaknesses, interviewers might point them out and tell you that it will be hard to get in with those flaws. Be prepared to discuss how you will try to strengthen your application if you weren't accepted the first time around. As an example, some applicants do research or get a job in health care as an EMT or medical assistant and then reapply. Also have an answer prepared for whether or not you would consider another profession if you didn't get into medical school.
