Pretty straight forward and not as stressful. Prepare basic questions like why DO, why RVUCOM, professionalism, re-read everything in primary and secondary application, it will be fine. The interviewers definitely have read your whole profile other than grades and scores. By the way, I think they somehow selected interviewers specifically for each interviewees. In my case, one of the interviewer was from my state of residency, the other interviewer had tremendous experiences in the city where I spent my undergraduate years and was able to call out details about the culture in that region very well.
