Again, remember how very variable this process is. For me, I was complete on 2-Sept and received the invite approx. one month later on 3-Oct. Hope this helps, but again, don't try to extrapolate too much from others' dates and such!
It really varies bebe. I received a complete card around the end of August and my interview was scheduled for Sept 11th. About 3 days before the 11th I rescheduled for October 2nd.
highly variable_ my interview came three days after i hand delivered the final piece of my application (my mcat scores) to the office. i am pretty sure frantz saw me do that and did me a favor, though.
-don't worry about columbia, though, they interview through feb/mid march. and all apps were in by mid-october.
I got their app complete notice on 10/15, but they still were waiting on my August MCAT scores. Their interview invitation came via snail mail and was dated 11/1.
