It is late, but not to the point where I would advise someone to not even bother applying that cycle. Usually, I would say that for somebody who is still wanting to apply September 1 or later. From what I heard, most schools review applications in the order received, and will say "we will get to your application when we get to it". Even though most schools have not yet filled their pre-December interview slots at this point in this cycle, they may still not have gotten through all applications received within the last month or two.
