You have a great MCAT, but that GPA is going to hurt at a lot of places.
Having your grades take a dip, when they were already low is also not a good sign.
Any reason you applied to so few schools? A reapplicant, with anything below average should apply to 30+ schools. The extra money spent is nothing compared to sitting out another year.
Not to be negative, but what are you doing this year? Until you get in, I'd always be trying to improve your app. Work on the GPA so you are a better applicant next year just in case.
To answer your original question, you probably need to show improvement in your app to get invited for a second interview. There are too many strong candidates out there for a school to waste time with someone they already rejected who didn't improve. If that MCAT is a new one, that would be a very good start.
Good luck with this cycle. Hope for the best, but prepare for the worst.
