I had a skype interview with a professor in Canada for M.Sc. admissions. This was 10 days ago on April 20. The interview went okay. He said he would talk to the graduate coordinator, check my application and get back to me by the end of April. Monday, May 2nd would be the first working day after the proposed end of the April month. I am not sure if I should email him back asking about a decision. Would this seem too pushy? What should I mention in my email? I would also like to mention that when I had emailed him to schedule the interview with my convenient timings, he had not replied. But a week later, I emailed him again and instantly got a reply back. So, I'm not sure if he's genuinely forgotten because of his busy schedule or if he's delaying it. I have no offers at the moment, although I am waiting on two more universities.
