There has been some good advice that I hope the OP takes to heart. However, as a former member of an adcom, I think it's probably best that you haven't gotten any interviews - based on how you've answered some of the questions in this forum, I imagine that you would not have been picked anyway. I know that internet response =/= interview question response, but I wonder how you'd have answered the following questions:
1. MCAT...Why so low? If you planned on answering this question with the fact that you only studied for 2 hours, this would be a red flag for several reasons: poor judgment, not being serious about being a physician, arrogance. If you wanted to say anything along the lines that you thought it was a pretty good score, I'd go back to your Mensa, etc, credentials and say that these don't necessarily jibe. How did your MCAT score break down? Did you have any numbers below 9 in any section? If so, this would be another red flag. Follow up question would be what do you plan to do about this? Hopefully, your answer would be to take the MCAT again.
2. Why so few ECs? This has been discussed, but I'd wager that if you were to say anything along the lines of, "I don't want to be phony", I'd probably counter with something like, "So, there were no clubs/groups on your entire campus (or in your city) that you felt that you could join?" Red flag for either lack of social skills, lack of interest, psych disorder (schizoid? autistic? though both admittedly unlikely). I would also wonder why, if you felt that nothing like this was available, you didn't start a group yourself.
3. Given the lack of ECs, I'd be interested in your personal statement. Why do you want to become a doctor and what have you done to give validity to your personal statement. Again, no ECs, so can't verify that way. So the only thing I'd have left would be your LOR. What do they say? Obviously, you probably don't know what those say, but because you've given the adcom so little to work with, these letters need to bring forth information about your compassion, dedication, +/- intelligence (the intelligence has been covered in other areas - GPA, Mensa, etc), why you specifically should be a doctor. If possible, you may want to talk with your LOR writers and ask that they speak to these things.
4. You are a prime candidate for the "If you don't get into medical school, what will you do?" Hopefully, you know how to answer this question (blah blah, try again, blah blah, if I can't be a doc then something in the medical community).
5. What do you know of medical issues? Medicaid? Medicare? Challenges facing your particular community? Tort reform? You would be likely to be grilled on these issues because your application doesn't speak to someone who wants to be a physician out of love of medicine, but because he figures he's smart enough to do it.
I hope I haven't been rough - I just want you to know that while you see yourself as a good candidate, based on what you've presented in this forum, you come off as a big red flag that some schools may not want to try and decipher when they have so many applicants who've given them so much more to work with. Two more pieces of advice: 1)talk with your pre-med adviser. Have them look at your app and give you some suggestions. 2) Talk with the school at which you applied and ask them what you could do to improve your application.
HTH.
