Well as far as I know, Geneva UAC will need staff since quite alot of people are about to bugger off. Get hold of the OPS managers, since they would know best, if and how to get into Skyguide.
But anyway don't expect any miracles, HR is as fast as a snail hurrying up the hill, I'd say same as all ANS providers.....
Good luck with your application and i wish you even more luck finding the people who admit that SG need controllers
