If you have another option,don't go to QR.The company is negative,makes you feel very bad.If don't have an option go,but believe me,it's not gonna be a nice ride.If you already have the rating it's ok,but if you don't a 50K USD will be your bond or 3 years. The compound is ok,if you have kids.
AIN KHALID GATE its a nice option.
There are lots of nice people and flying the line is ok,with a very nice network flying the A330 or B777 (future) ,but the India mafia will screw your life big time in the roster.YOU MUST KNOW THE QCAA FLIGHT TIME REGULATIONS BY HEART.
The best fleet is A340 followed by A330,B777 and the worst A320 with lots of stupid new captains they doesnt know nothing.
The most stupid thing is the Not Allowed policy for some type of food ( First Class and Business class) in the plane.It's awfull,but most of the cabin crew will give to you as well.
Driving is worst than any place in the middle east.The other arabs who lives there are greedy.
Normally most of the Qataris are nice,but they are the minority.
Believe me you gonna turn to be a racist because of some anoying nationalities.
What to do!
Anyway good luck on your choice.
