Hi
The best advice I can give is be yourself.
The format of the day is:
1. Registration (You'll need you passport and Exam Certificates)
2. Video and talk from current crew members on a typical day.
3. Spit in groups for group activity (icebreaker, team work, role play)
4. Maths Test (noting too taxing, currency converting, adding up a list etc. You can use a calculator)
5. Then you have a break, after which you come back and are spit into groups. 1 being unsuccessful and 1 being the interviews group.
6. Give further information on the job.
7. Lunch
8. Give interview time.
9. 2 to 1 interview. (The question are based on "Can you give an example of when..." These will related to Teamwork, Exception Custer Service.)
10. You find out after about a week.
Depending on base, you may have to wait. I was to be based at EMA, I was put on a waiting list. It can take some time. I waited a year for my start date, put I have it now.
Hope this helps, any further info let me know.
Cheers
