Meanderson,
Don't worry about a late interview date. It really shouldn't affect your chances for admission.
Like all med schools, Emory can get bogged down by applications at times. To be fair though, didn't August MCATers receive their scores quite a while ago now? A friend of mine who also took the August MCAT has already interviewed at Emory, so August MCATers are not necessarily all doomed to late interview dates.
