I'm throwing my hat into the "haven't heard anything" pile as well. I interviewed on a Friday in early January. When I was there, Dean White said that the Committee on Admission would meet around the middle of March and that students should hear back sometime in late March.
since i didn't get the call last week i thought i didn't get in. However, I called Johns Hopkins today and they said that my group hadn't been reviewed yet. Can that be correct??? I interviewed Feb 4th. Anyone have any info?
