I applied through an employee referral. The process took 3 months. I interviewed at Qatar Civil Aviation Authority (Doha) in Jan 2014
Interview
No formal interview, if they like you, you are lucky, you can be hired. Need strong influence for recommendation but the offer takes too much time, I suggest apply for another company that can give you meaningful and career growth.
I applied online. I interviewed at Qatar Civil Aviation Authority
Interview
I did not go through interview process for reasons only known to them. Apparently they organise skype interviews. I did not have to do that either. I recommend that you prepare for skype interview anyway.
