What can I add that my colleagues have omitted. Well not a lot actually but I was on the recieving end not so many months ago. The so called technical interview isn't so technical. They aren't looking for a great depth of knowledge at this stage but a more general appreciation of the job. Try ABC of Air Traffic Control by Graham Duke published by Ian Allen. I read it cover to cover the week before and it really helped. You have probably been told this but a visit to a unit is a MUST. Try to go and see a tower and an Area centre. I just went to LATCC personally. You'll get asked some simple mental arithmetic pretty much like the samples they send you. Most importantly think before you answer ! a wrong common sense answer will be better than waffle. The personnel interview is wierd, questions like "have you ever upset anybody !!" but answer as best you can and hope. As for the computer tests, everybody on my course was convinced they had failed them. The consensus of opinion is on the "flying Numbers" test, you'll know it when you see it, concentrate on the flying numbers and do the maths questions at the bottom if you can. The bottom line is bone up on what you can, be enthusiastic and confident. Good luck and see you at CATC soon.
