So in my anxiously awaiting applications to even start being reviewed, I've read about the timeline of interview invites for PhD programs from last year. I've come across a couple schools that people talk about having "pre-interviews" for over the phone before being invited to actually interview. Is this another step in the weeding out process? Can you get a "pre-interview" and not an in person interview?
If yes... what is it? How does it differ from the normal interview? I've looked at the websites of schools that apparently do this (UConn and Yale both come to mind) and they mention nothing about it.
