The actual physical interview was very brief, more like a chat with a few questions and clarification of my online appliction, felt informal and fine. Then there was meant to be a group activity type thing but as there was only two of us in this instance we did it individually, its basically a written scenario which they ask you to sort out in terms of how you would deal with the issues set out - ie you arrive for your shift and these are the things that need doing - how would you prioritize them etc, there are no real right or wrong answers they are just looking to see if you have common sense I think.
