Gustav, the situation is weird. I emailed a POI, who knows me, and he told me that he wasn't sure but probably I wasn't in at this point (but he admitted that he didn't know with absolute certainty since he is not on the graduate admissions committee).
Besides that, I emailed another person 3 days ago but she didn't answer at all.
I think they decided and we are rejected, since it's February 13th. But this silence is weird nonetheless. I take for granted that the interviewees are not here or don't want to disclose any info (I'm even thinking about the possibility that the adcomm might have told them not say anything, at this point...but maybe an exaggeration on my part). I would like to be wrong, but unfortunately I don't think that's the case....
