Are you sure about that? Cos from what I have gathered is that the second interview is done usually when the first interview was not good/inconclusive. And a lot of people get in with just one interview too (Source: Global-derivatives, Quantnet)
Also, if you notice the Tracker, many of the applicants have gotten their results on the R1/R2/R3 deadline dates (not all, but a lot). I know its inconclusive, I'll use that also as a sign of people being intimated by e-mail on deadline day.
I am still hopeful.
