Apparently they have "experienced some delays" for certain files. I interviewed on Jan 18 and have not heard back yet, so don't be surprised if you have to wait longer. I would suggest calling in just to double check.
I had the same question..I interviewed on the 22nd so I wanted to know what their normal timeline was. I heard many peope hear back within a couple days but I haven't gotten anything in the mail yet. Anybody heard anything from the Feb 22 interview?
