Hi, I am a new one on this thread!
I had my phase 2 and 3 on wednesday and yesterday.
You obviously need to talk a little during the phase 2, but they firstly assess how revelant and interesting are your argument! So avoid to be a talking machine saying BS, be open minded with the others, ask for the opinion of the others candidates etc...
on phase 3, well, you want to become an ATCO so you need information on the job, as well as basic knowledge about aircrafts ( how does it fly: bernoulli's principle, intruments board...)
of course search for eurocontrol; localisation in europe, what do they do, the more you know the better it is!
I was called this morning and i am in for the september course!
PS: i am french, i am good in english but far from being bilingual, and because of a stain on my suit i was wearing blue jeans!
