I just got waitlisted for them too. I figured I was out since I didnt get offered an interview, but I guess they dont have to interview you to waitlist you. Keep me updated if you ask them about your position. I understand why schools usually wont give you you position, but at least a range? GW is my #2 & 3, and starts later than my #1, which begins in June. I would like to know from them if I have a shot of getting in, because I would consider it if I had been admitted.
If they tell you anything, let me know!
