i got an interview in mid september, two months after i turned in my aadsas app. when i called for to schedule an interview, i was told that i got one of the last dates for the year (december 6th).
I sent my app. in about mid-June and heard back from Columbia in mid-September. I called to schedule an interview and they let me have my choice, so I interviewed in October. They were one of the longest reviewing my application, though.
