You're not too late. I just interviewed at VCOM and they said they are going to take a bit longer to give us (the first group to be interviewed this year) our answer. They said it is because we are so early in the interview process that they want to go through some more applications before giving us our answer. Drat, ususally it is 2 weeks, but she said it may be up to a month.
So I think you are fine. There are a bunch of August MCATers, so don't worry about it.
Good luck.
