I totally get you what you are saying. I am in the same boat. I see people getting acceptances or interview invites every day on the gradcafe, and my inbox is so quiet. I did a very risky sort of follow-up (can't elaborate on how or what as there are business school reps here on urch), and learned that I was not in consideration or short-list in four Universities. From the rest of the Unis, either I got replies that their process is ongoing or no replies. At this moment, when I am typing, I am stressed out. I know that I should keep myself calm and there is nothing much that I can do except for waiting, but we humans have a very odd sort of psychological makeup, and we don't like to lose, be it a Ph.D. admission offer or a tennis match.
Anyway, I even saw that the Ross (Uni of Michigan) had rolled out some rejections on the 2nd Feb, and the pattern of the Uni of Michigan is that they roll out all the rejections for one particular program on one day. They did the same for Mathematics, and some other programs. Thus, I am not sure whether to feel optimistic or pessimistic? Again, I am not sure about which areas did the Ross roll our rejections in?
Also, I think even the Questrom have starting rolling acceptances today.
Congratulations to the ones who are getting this notifications. :) But is there anyone else who is refreshing his/her inbox every hour like me and eagerly waiting for some sorta notification?
