I'm gonna have an interview in this month for ph.D position, to follow a project proposed by professor. I need some suggestions about this kind of interview. Thanks in advance

Hi, I have an interview this week for a project that has already been proposed. From talking to others it seems that each interview is different and there is no set format. I would advise you to read around the subject you are studying, read your potential supervisors papers, understand the project so you can ask relevant questions and to try and relax (difficult I know!). Good luck!
