Yeah it's true, personnally I decided to totally forget about this "opportunitie". Giving 3'000 USD for some reason... to a company based in Philippines, you'll juste never see your money back!
But I understand people who tried at least the interview. For my part I ended my flying school for now 2 years and I have tried a lot of possibilities (and especially not Line Traning!) , so when you see this kind of job, located out there, it seems like a dream lol
