Post is Service Team Leader in Terminal Operations.
The Challenging situations were quite roll specific, so don't read too much in to them.
The common factor was that professional actors were used to play certain individuals and character types.
For our assessment the Challenging Situation No. 1 was a meeting with a Supervisor from an airline (you work for a ficticious London Airport, the actor works for a ficticious middle eastern airline). The written notes explain some background information regarding an issue between a couple of the airline's check-in staff and the Terminal's operations. You have to conduct a meeting, exactly as you would in real life, with the aim of getting the airline's supervisor to see the reasons for the requests made of its chek-in staff.
The second was a performance review with a member of your team with a few issues to resolve.
One thing that BAA were exellent with was providing information in advance of the assessment day, and the help that the Hunter Roberts people gave during the day.
Feel confident that you will not feel lost or baffeled, but at the same time the written test is not especially easy (all of us ran out of time - 1 hour), and the challenging situations feel very very real with the professional actors.
Of course your day may be totally different - I hope you get the post you're looking for.
