Now, you call it a big decision, so here's my advice: DON'T
Working in the airline industry in Qatar means that you will have to follow some very particular rules:
-curfew after 10p.m. for members of the other sex in your accomodation
-in case you should meet the person you want to marry, you have to ask the CEO for marriage permission.
-if you report sick, you have up to 3 different people from the welfare department calling you to ask for the reason.
-welfare has a key to your apartment and also to your private room. they make inspections whenever they want..privacy ?
Only come to doha/Qatar if:
- you have a waterproof backup plan
- you intend to stay for 1 year (2 years maximum!!!!) as an experience in your life
- you are not afraid of loosing the fun of flying and getting disgusted
- you like or at least don't mind the idea of being kept like a personal slave of the CEO
All the best with your BIG decision.
And again: if you kind of enjoy the job you have now...DON'T leave it behind for coming to Qatar. It's not worth it.
