I called today as well and the lady told me the same thing. She said that we will not be re-reviewed until April after all the post-December people interview. It sounds like all the acceptances until April will be for people who interview after December 1st only.
This is consistent with pre-dents. Not one person who got accepted after Dec 1 interviewed before December (only those who got accepted after April).
So sorry to be the one to confirm the bad news but it looks like we will all be wondering whether we get accepted or not until April. That is, if they don't reject us first. Looks like I need to find a new number one school until then.
