Guy's, it's tough to give you questions as it's a bank of questions so you might get completely different ones to me.
I remember there being a why RBS and why this division, which I think must be the same for all VIs. The rest are strength and competency based, so tell me about a time or imagine you are...
You also only get thirty seconds to prepare answers so my biggest bit of advice is making sure all the tabs you might need for information are easily accessible. Take your time, talk slowly and clearly and get straight to the point.
Good luck!
