Response time of a research supervisor I had an informal interview with a foreign professor on Skype and things went well. We talked on Friday and he said he will discuss my case during the meeting for recruitment of students. He showed interest and we exchanged emails for the possibilities of scholarships. Mean while he even sent me a book and lecture related to work but he did not replied my email on Monday. I thought he must be busy due to his meeting and its Thursday and still have not heard from him. Tomorrow it will be a week of my interview. Its just 2 or 3 days but should I be worried or wait, until he gets back?
Sara, I would wait another working day (Friday), and on upcoming Monday morning, I would send the following email, so the he/she could respond the beginning of the next week: 

Dear Prof.X

I would appreciate if you could let me know about the outcome of the interview?

Kind Regards, 
Sara
