Most of these application process and tests are sometimes luck.
I felt really confident I made it to the next round with Aer Lingus had a brilliant CV, Cover letter, did well in the test (I think). Currently work in the aviation field as an engineer but unfortunately didn’t make it through.
I don’t know what recruiters are looking for in this field, people with aviation experience or people with no aviation experience. There’s loads of people with aviation experience such as PPL pilots, cabin crews, airport workers etc are not getting through even doing well in the tests etc.
