Hi,
didn't apply to CMU ECE, rather to CS Robotics.
However, I did apply to UIUC ECE and it seems that once again this year they are taking their time with decisions. When I emailed them at the beginning of last week, they said that faculty were still in the selection process and that decision would be made by April 1.
Well, April 1 is tomorrow, we'll see if they can keep their promise. I studied at UIUC before and know some of the ECE secretaries. They are very nice and helpful and it's probably not their fault at all, but it seems that something is going wrong in the department as far as getting decisions out in time.
