Since you are an ATCO already you probably know how hard it is to come up with a test which can give a 100% succes rate for possible ATCO's.
A side from that such a test is only able to capture some kind of inside of your abilities on the moment of the test.
If you do have any suggestion how such a test can be improved everybody is more then interested in knowing how.
I can understand you are disappointed about it all but to be bitter about it and to wish Eurocontrol a difficult future is a bit much.
I am sure that with your experience as an ATCO and all the vacancies around the world you will have no problem finding a different position.
All the best
