i applied within hours of the app. opening. within a week, i was contacted by 4 schools for interviews. it seemed very cool!! i would go to as many interviews as you can. being able to compare schools is huge! just because one school is touted as being the best doesn't mean it will be the best for you. check 'em all out, and go with what feels good to you.
I submitted all of my application on 5th and got 2 interviews the next day... I haven't even turned in my recommendation or the transcript yet. they're on their way now.
