That's crazy. I don't know if I can wait much longer!
I got my invite on December 23rd and I had until today (12/31) to select my interview. So there could be a chance that some people may decline their interview today and those of you still waiting could get good news. Also, I had a choice of either January 18/19 or 25/26. Good luck on the wait and I am still waiting to hear from MN my IS (so I am totally with you). Fingers crossed and let's hope to hear good news for the new year.
