No need to panic everyone. LOTS of interviews to still be sent out.
Admissions office closes 12/23 I believe, BUT interviews can still go out while the office is closed. I got mine 12/28 2 years ago.
I know how hard it is to wait for that interview, trust me, I still remember the stress and agony vividly. But to save your sanity, I highly recommend trying to relax and just not worry about it until the decision deadline date in late January.

I know no one will listen to me, but at least I had to try!
