To anyone who's thinking of pm-ing me to ask for what questions they ask, this is the response you'll get - the same as the others who've asked already. I'm all for giving advice (and I've found some useful help on here - Cheers!) but I'm not going to tell anyone how to get through their interview....
I'm afraid I'm not going to tell you (or anyone else) what questions they asked or what the group excercise is, apart from saying that it's an excercise to see how you work together and there's nothing you can do to prepare for it.
Regarding the questions in the interview, they all based around the topics given to you in the Stage 3 PDF - read that and have a think about some situations you've been in.
Good luck!
