Momo95 did the flight school you graduated from offer any type of job placement or at least networking opportunities with previous grads? I wouldn't say money down the drain but definitley keep your options open if Qatar doesn't work out. I don't think anyone can guarantee a job but many flight schools have partnerships that at least get your foot in the door with a Conditional Letter of Hire or guaranteed interview. If not get in contact with grads from your school that have a job with an airline.
