I think I meet a weird alumni interviewer.
He sent an email to me on monday saying that I needed to call him to schedule a interview,so I called him on Tuesday and he told me that he was busying and he would call me later. However,he never called me. I waited until Friday and sent a text message to him.He said we would have a video chat on sunday.Then I asked what would be the exact time and he never answered me.It is sunday morning here. I'm very anxious because I felt like the interview will happen at any time. Is it appropriate to send a text message and asked the time. I think it may seem annoying since I already sent him one.
