I'm an (international) electrical engineering applicant applied to some top-10 graduate programs in US (say, MIT, Caltech, UCB, etc.). As I check the entries of "thegradcafe.com" every day associated with the programs I've applied to, there are many entries which declare interviews with some POIs. So far, I have received no interview requests from any target school. Thus, I'm a little bit both curious about the importance of interview and anxious about the interpretation of such a lack of interviews in my case. To be specific, are all admitted students to top-tier engineering programs invited to interview before getting admitted? In other words, should I expect to be rejected if no one invites me to any sort of interview?
PS. If it helps to clear the situation, I'm currently an M.A.Sc student at a well-known Canadian university. So, both my university and my supervisor are pretty famous to the research community of my field.
