Maybe its a trap
Maybe they tell you before the interview "whatever you do, dont say you want to fly jets", and then in the interview they ask where you see yourself in ten years, and apparently the ones who say "flying Dash 8s for you!" are the ones who are telling porkies...
Trouble is, it unfairly discriminates against the people who legitimately DO want to remain driving dash 8s... the very people QantasLink should be trying their hardest to attract and keep!
