Costas,
I am not in a position to know if they have interviewed or not, but I'll tell you a few simple things about Aegean. The aviation market in Greece is small, and most of these "new pilots" are sons of pilots....so they know people and they don't really have to apply to get an interview. Greece is Greece even in a private company!
Secondly, recruitment will happen whether Aegean want to or not, the pay is dropping, the hours are near limits and the roster is far from stable! With the way the hiring is going outside of Greece they will lose quite a few pilots even if they don't want to leave Greece, just because it hurts to watch others live a normal life and make double and triple to you.
The only advice I can really give you is send your CV to the HR email address and keep your fingers crossed. There will be hiring....just a matter of time. Any specific questions you can always private message me.
