I also interviewed with a PI at CU Boulder last Friday and he said that 200 people applied for 2 open positions, so anyone who didn't make the first cut shouldn't feel too bad, as these types of situations rely on fit just as much or more than how good you are as an applicant.
UNC BBSP Neuro has sent out all of their invites. I was told that there is a small waitlist for interview invites, so it’s possible you could be on that, but if you haven’t heard anything yet, the chances of getting an invite aren’t great, unfortunately.
