Delay is 3-5 years , could be more. Definitely no job after

if you have a good nationality you can make some calls but now days not easy

The delays are real. Saw one cadet from end 2017 until now still training.

Actually, I have no idea about the delay, but they seen to be taking cadets for this year now. A lot of them are about to start their ground school too. You may be wondering how I know this?
I actually interviewed one of the cadet pilot from the academy, feel free to watch it.

which nationality is banned to join ? Behaviour problem with Egypt students ?

Hello,
I don't think so, the best option is to email Alpha Aviation Academy or Air Arabia, I am certain they will clear all of your doubts!
