I got the email for requesting the interview early March, from one of my POIs. He told me at the time that the committee is finalizing the decision. During the interview I was also told that the decision should be sent out by the end of March. The prof said they were making some ranking from all the interviewees and finally would make the decision.
Is the interview process common for every applicant? I thought I was at around the borderline and that was the reason why I got the interview opportunity, but now I guess it is not true..
BTW, I've never known about grad cafe forum!! This is cool
