Guidelines

These remarks are of course unofficial: there are properly laid-out guidelines about what a supervisor is supposed to provide, and what a supervisee is supposed to do, and your university regulations will set them out. It is, however, the case that these guidelines get widely interpreted and variously applied. You could politely draw the regulations to your supervisor's attention if you feel that you are not getting enough time. It would be as well for you to check that you also are meeting the required standards!

So choose someone that you think you can work with, whom you trust and respect and who is keen to work with you too.
