there's definitely a lot of time to still receive an interview.
the admissions office divides applicants by the region of their undergrad colleges- thus the boston area schools are in one batch, nyc schools in another, etc.
they do an initial review to cut out maybe half the applicants, then forward the other ones to the secondary reviews.
i took the august mcat, and interviewed early jan. (but i went to dartmouth undergrad, and they have dartmouth as its own "region" in terms of the groups.
good luck.
