Hmmmm.. a few things.
No interview doesn't equal to ding. It means WL or ding. So hope is not lost. It just means more waiting and more ambiguity, which we dread the most. And interview doesn't mean admit. Actually, similar options apply - WL, ding, or admit. It just means more likely to be admitted sooner. So yes, I can be drinking as well.
Also, how can one receive an invitation on a decision notification date? If a R2-er gets one on 2/15, is he in R2 or R3? In other words, it doesn't make sense. I know for a fact that people with stats less stellar than mine got into HBS. But that doesn't mean that I should apply and expect an admit.
The app season began back in October last year. Most of us applied to R1 or ED for a few schools, and while some of us were really successful (I can name kevintay, bless his admit from Johnson and Tuck), some of us weren't, including myself. People feel edgy because of unpredictability of the outcome, NOT the nature of the outcome. I'm all for being nice. But at the same time we are all big boys and girls.
