I was there for an interview on Mon Feb 7th, and Jennifer Welch said that they are currently 3 weeks behind in reviewing candidates. If I remember correctly, she said that at the adcom meeting on the previous Wed, they were halfway through interviews of 1/18.
It does not answer your question but I interviewed the week before you (Jan. 19) and Jennifer Welch called me yesterday. You should hear soon. Good luck! 🙂
