I'm so glad to hear it went well!
From this point, there's no telling when you'll hear back. Some people hear back days after their interview, some people take months. When I was going through the program, I did my phone interview on January 29th and didn't hear back until April 7th-- a week before the deadline to hear back!
I would follow some of the recruiters, namely Christy @ChristyRecruit and Stefanie @StefanieDCP. Often times, they will tweet when an incoming "wave" of acceptances is going out, so you'll know when to check your email! Other than that-- try to occupy your time as best as you can. I know how nerve-wracking this is! Good luck!
