Dudes/ettes, as a fellow interviewless R3 applicant, I know what you're going through. This past weekend I was really bummed thinking about all this and how I don't have a single admit yet. The usual thoughts like, "so much for my future" and "I suck".
I decided look through last year's thread, however, and discovered that the R3 applicants went through the same thing. Other than a random early invite here or there, the R3 invites didn't really start until the first week of March, and they continued right up to the decision date. One person didn't even hear anything on the d-date, and then got an invite about a week later! With respect to the timing, last year lots of people were saying, "only 2 weeks until decision day, I'm screwed." Then they got an invite that said they would have to complete their interview by a certain date (as short as 2 days) if they wanted a decision by d-day. The alternative was simply that their decision would come a little later.
This all gave me a great sense of relief. Given that the GC membership is probably stronger on average than the overall applicant pool, it seems likely that the same thing is happening this year.
