sorry to hear about that Naem. The good things to take from it are:
- you know you have natural ability to become an ATC (passing phase 1 and 2)
- anything within the interview can be imporved with practice
- If you re-apply i dont think you have to do phase 1 and 2 again
You're only 22 so you have plenty of time to re apply. Not just to eurocontrol, but nats and local other authorities around.
Good luck with whatever you decide to do next!
