Hey kmurrin,
I was also rejected from UCSD this morning, but I heard from my POI about three weeks ago that I hadn't been interviewed.
Like you and freecube, I have not heard anything from UCLA either, but hopefully we hear something today/tomorrow. Is there anyone on this site that has info for UCLA, perhaps that they have certain days interviews are sent out, etc.?
kmurrin, if you still haven't heard anything from UCSD after today, I would contact the grad committee, as you should have heard something, regardless of positive or negative by now.
