It's very laid back and conversational. You'll have a few presentations- on the school, financial aid, the INOVA campus, etc. Tours are given by M2 students. The tour guides have
absolutely nothing to do with the admissions process. Your interview (singular) will be with a faculty member or M4 on the adcom. They normally last 60-75 minutes. Again, they keep it very relaxed and conversational. The interview questions will be simple and straightforward. They'll ask about what you do for fun, clinical experience, research experience, blemishes on your application, etc. I wasn't asked about anything related to ethics or the ACA. If your interview is in the morning, you should be done around 1pm. Afternoon interviews normally finish up around 5-6pm, I believe.
Getting an II means that you've got the general qualifications they're looking for on paper. The interview is really just test of how well you handle sitting down with a total stranger and chatting for an hour-ish. Just be yourself and remember that all of the interviewers have well-trained BS detectors.
After your interview, you'll be ranked on a scale (I believe it's something like 1-5). The interviewee rankings are compared after the all of the interviews for that round of offers have completed, and then their decisions are sent out. You'll either be accepted, rejected, or placed on hold. If you're placed on hold, you'll be compared with the next round of interviewees and could potentially be offered a seat during the next set of decisions. After all of the initial admissions offers are sent out, all of the applicants that are "on hold" are reviewed again and either rejected or offered a spot on the alternate list.
I hope this answers some of your questions. Let me know if you have any more. Good luck!!
