Applied to PhD position but no reply Recently I saw a professor advertising an open PhD position in his group. He asked students to submit CV and motivation letter. I sent an email but received no reply. Two weeks after that I sent a follow up email, but still no reply. How much time would be reasonable to wait? Should I give up already? I know the professor doesn't owe me a reply, but since the position was advertised I thought he would sent an acknowledgement that the application was received. Am I wrong? Is that the common thing to do?
Some people are spectacularly slow. I got a phone call inviting me to an interview for a PhD at one university four months after I'd given up, applied elsewhere, had the interview, received the offer, and accepted that offer. Wait as little or as much time as you feel like waiting, frankly. I'd certainly be looking for other PhD opportunities, regardless.
