I submitted 12/2. Received an interview invite around 1/13, interviewed 1/26, went complete 1/27 and have been waiting for an answer since.
I want to comment on what everyone is saying about how there haven't been any decisions (at least acceptances since 1/22). Keep in mind that school just resumed the week after that. I know that class schedules shouldn't affect the admissions process, but there might be some correlation - did information sessions kick up again - were they recruiting new Hermes Society members? Also, I live in New York and the weather (snow) here has been brutal over the past few weeks. I wouldn't be surprised if admissions personnel couldn't make it in to the office or if meetings had to be rescheduled or canceled. I'm willing to bet that the confluence of all of those events did slow down the process a bit.
Best of luck everyone. Like many of you, I'll be staring at my inbox and chewing my nails until I receive a decision.
