I emailed Columbia about my Epi PhD application since we were supposed to hear in late Feb. They said my application is under review and I should hear back within two weeks.
Haven't been invited for an interview.. Maybe I'm on some kind of an unofficial waitlist?
Oh boy! I didn't get an interview. Hopefully that's not a necessary step towards admission!
Columbia stated in the original email that a decision should be expected by late February. It's getting pretty late!
