The format of the selection test day is as follows:
Arrive am and check in - you'll need ID such as a passport to prove you're not taking the test for someone else. You'll be divided into groups - note which one you're in. There are 4 sections to the selection tests:-
1)ATC knowledge paper - general questions on your level of knowlege of UK ATC. All the answers are in the brochures you've been sent. This is therefore a test of your ability to study & learn by youself and assimilate the information.
2) OPQ questions - multi-choice about personality traits etc.
3) More OPQ type questions about spatial reasoning etc.
4) ATC presentation - by an operational ATCO. Usually a video show and the opportunity to ask questions about any ATC subject. Useful, especially if you do this before the ATC knowledge paper.
All questions are done on paper at this stage.
If you are successful you'll be invited to interview and more personality questions and tests. Some of these are computerised.
There are 2 interviews. One is an ATC Technical board with an ATCO interviewer who is looking for evidence of motivation such as unit visits; the ability to fit into a team environment and the ability to think under some pressure.
The other interview is with personnel and is much more frightening!
If you're successful at this stage you'll be offered a place on a course at CATC in Bournemouth.
Good luck.
