I can reply to you in English.
I have no idea if they are planning another recruitment stage this year, us in the holding pool are still waiting for a call. The holding pool is valid for summer 2021 as well. A few days ago they asked us to update them immediately about our current notice period and whether we are rated or not.
As for the test, I would say ACE is a good start, but the test has also questions that only a person working for another operator would be able to answer, like questions on MEL items categories. Unless of course, you were already a genius during your ATPL theory days!
