Hi Missdyk! You have to follow the Etihad requirements because they are those who will hire you, not this silly recruitment agency! I applied 2times via a recruitment agency and I had really nice experiences with them! For those who are residing in Europe I can recommend
-www.best-aviation-jobs.com Here your contact person is Mariola Tamnichka! She is soooooooooooo nice and helpful and you just have to register and you will get an invitation if you meet the minimum requirements!!!!! Mariola organises Open Days for Emirates Airline in Eastern Europe and Germany!
next one (Etihad)
-www.flyhigh.sk. Here your contact person is Maria Zilkova, I called her and she was also so nice to me!!! She invites candidates for Etihad Assessment days also in Eastern Europe (Prague, Warsaw, Bratislava etc.)
As i live in central Europe it is not a problem for me to go to these destinations with the help of easyjet or ryan air or other low cost carriers! I hope I could have helped you and wish you every success!!!!
