Baz,
I got a phonecall yesterday Afternoon So I guess I will might see you in Exeter on Thursday!!
I asked what the format of the interview is on the phone. They siad it will be a few standard questions lasting about 45mins to an hour. Asked one of my mates who is already working there and he told me its a informal chat nothing too tricky!!
Oh yes Know the company history
Good Luck
