I'll throw in my two cents. I had 6 II in total, and ended up with 1 acceptance, 4 waitlists, and 1 post II reject. When you mentioned "if I get one interview, I know I'll get in", I would say I certainly considered myself in this same category before the cycle started. And yet, I had vastly different results than you.
If I've learned anything from this cycle, I have just realized how difficult medical school admissions is, including post interview. Now perhaps my own perception of myself is off, but I was surprised to have the post II percentage that I do. To qualify myself, I am someone who has worked in sales, teaching, and management for years. I am very comfortable speaking with others and talking in almost all capacities, and practically thrive on it. All this considered, my post II still was low. I was even told from several of the schools that interviewed me that I had excellent interview scores (no joke, I called and asked!). Yet, I still found myself on 4 waitlists.
My own theory is that, at least at the schools I've interviewed at, the interview is a major component of the admissions process, but it does not necessarily make or break an acceptance, as a lot of people on here might think. At least, this was my experience with the process. I am fully willing to acknowledge that it is possible I am overconfident in my abilities, but after receiving the results that I have and the feedback that I have, I have a different perception of the interview process. I also just think that med admissions is getting more difficult every year. Currently, though, I don't think it is so bizarre when I hear about an applicant with many II but fewer acceptances.
Just my two cents. Regardless I am SO happy to just have one acceptance!
