As posted, the interview is solely a leadership and team work one. i.e give an example of when you've had to delegate to others in the work place.
My advise, look through these posts and list all possible interview questions. then think of answers for all. Then practice, practice, practice.
For the computer based tests- cockpit web is pretty much identical to the real tests. i even found that half in the BA tests were easier than cockpit webs. Practising these will give you a massive chance of passing. For me that was the one thing that you can pass before you've even arrived at Cranebank.
Again i can't stress how important it is to practise for each part of the selection. I worked for about 2 weeks before my tests solidly. but it all paid off in the end.
Good luck
