I don't understand how they operate at all. It seems like it would be super confusing to be receiving new applications before they even finish reviewing the ones they do have. I think Haas is trying to manipulate their yield (by seeing who withdraws their applications due to unusual round deadlines) and to make decisions with more information (by having rounds overlap). It's kind of like they're hoarding applications to see what else comes in.
I'm lucky to have admits elsewhere, but their timeline really messes with us! Their process is decreasing my interesting, and I bet I'm not the only one...
