I don't really understand how to apply for a PhD, or the funding, or what you're meant to live on for three years... so that's one question to begin with.
But... I have been asked numerous times to do one, and apparently I have my pick of supervisors (sorry if that sounds big-headed) 
My question is, does the calibre of university come into it? So say, Nottingham uni vs. Nottingham Trent?
Which is most important - the calibre of uni or who you have supervising you?
Is it true that the most difficult job to get after it is the first one, but once you've obtained your position then you're in a good place? Will you always be employed/employable if you have your PhD?
Any tips most welcome
