sana depends what position you are looking for? With Masters in IT I think you would be interested in some IT related service.

For ATC, CAA has advertised every year since 2008. Other posts also keep coming from time to time.

If you view this page:CAA Jobs 2011

you can get an idea of their advertising in 2011.

The test for ATC which we had included very basic English, IQ, general knowledge questions.

CAA always has its own recruitment, separate from any CSS or other official service. Ads are always given in a newspaper. This is followed by a written test, then an interview, medical (if required), and training.
