Going out buying popcorn... :/
First, I do not support the programmes with the scheme of buying something with the chance to get a job... maybe... OR - maybe - NOT.
You pay a whole bunch of money for a TR. Soft version of P2F. Yes, of course in the modern world this scheme is considered normal, BUT at least just pay if you sign a contract - before TR.. The you will not only be "considered" (or having "the opportunity to be assessed") after paying 10,15 or 20k.
But next to this, if you're not even qualified according to FlyDubai as they have as the first requirement:
"• Age: Minimum 20 years / Maximum 30 years (before your 30th birthday)".
You just said you´re 19.
Nice Week,
