So, seems that the process is ongoing. I have received an email that sounded like "be patient and wait". The screenings are spreaded along the whole coming year, but no chance to have exact dates or periods. I guess how people can organize their roster, their days off in order to participate to the selection.
Is not like Ryanair that catches unemployed students and call them also for the day after, here there is people who lives in all over the world and they needs infos in advance to move back to Europe.
Btw wait and be patient. There is really nothing to do.
