Thanks people

Yeah, I know they are not supposed to be that bad, but the type of work I am applying for = interview panel of 3 people, and lots of tricky case-based questions, e.g. "you have a client with XYZ disorder, how will you assess them and what is your management plan?" etc. So it'll be full on.
Ospi - yep, I plan to do LOTS of preparing. The thing I am concerned about is that I am not very good at working out what things to say unless they ask me the EXACT question I have prepared for, which is unlikely. I'll go "crap, that's different, I wasn't ready for that", and forget that I have all this knowledge I can apply. I have a bad habit of panicking when people ask me unexpected questions. Not a good thing. But yeah, I should be OK.
MonkeyMagic - yep I'll be going for it! I need a job! It came about because I have just graduated from uni and started applying.
