Hey, congrats on the interview!
I also skype interviewed with my POI at UCSC (developmental) 2 weeks ago but I wasn't aware that they weren't doing an interview weekend. Did your POI tell you that they weren't doing one? So much more pressure knowing that the skype interview was the only one they'll be doing!
Also, I was told I'd hear back within 2 weeks but haven't heard anything yet. Did your POI give you any details about when they would send out decisions?
Thanks & good luck!
