I had a face-to-face interview at a German University for a PhD position on Feb 12. The project is co-supervised by two professors. I was asked to prepare a presentation of my Master thesis for the interview. I was told that they invited only 4 out of 90+ applicants. It went okay and the sit-down interview after that went more or less fine. They seemed to value my enthusiasm while doubting my mathematical backgrounds. At the end of the interview, they asked me to send my transcript. I sent it the very next day (Feb 13) through email and got a reply from one of the professors on the same day that said they would soon be in touch with me regarding the position. However, I have not heard from them yet. I sent an email politely asking for an update last Friday (March 1) to one of the professors, but no reply again. Should I send an email to another professor? Or should I wait? Also, does it look like I am being refused? Any help would be good.
Thanks!
