It depends on the school. A few accept their second round on Jan 15th, and a few meet that day and wait a week or so.
But there's pretty much a dead time between Dec 1 and Jan 15. So best of luck to all of you waiting for round two hopefully it is better than round one. Also if you don't get accepted by Feb 1 or if you haven't been interviewed by Jan 15 it's time to start looking for a plan B. The cycle is far from over but you don't want to be lost come graduation. Getting into an SMP was a big relief for me last year, at least I had something.
For those looking at plan B here's a good thread to start:
