I think I would not help to send e-mails to send follow-up e-mails to the professors and I also think that it's not a common practice to get positive responses from professors (the common practice would be to hear nothing :))
On the other hand, I feel you. I'm quite confused about the interviews, or not interview thing actually. For example, Wharton website states "they do not offer interviews before making decisions, and after they make decisions, they invite people for campus visit". But I also see people posting interviews with the same school (contradictory, kind of.) Some schools, like Haas, states that they do not have a "formal interview policy". Some schools explicitly say that they will invite for interviews.
So, my friend, I feel the same confusion and hopelessness you have right now. But I approach this with the following way:
- Schools that explicitly stating "no interviews" or "no formal interview policies", I'm still kind of hopeful even though I see Gradcafe posts. When I say hopeful, it is like, "OK, we are not dead yet."
- Schools that explicitly states "there would be interviews" and I saw Gradcafe or Urch posts on these schools - those are like we are almost dead.
- Schools that say nothing and no interviews posts on Gradcafe, I do not know. There is still hope!
Actually, I will have some kind of hope until I get the decision letters of rejections (or offers). :)
