I recommend QR, I've been living in this country for the past 15 years. Qatar in one of the fastest growing and developing country in the world and the same for the company. They've achieved many thing, increased their fleet in less than 20 years of operation. Don't forget that Qatar is very safe, So if you're looking for a safe side, Good money, relaxed life go for QR.I don't know the staff yet but i've met lot of them and for me they're just perfect. More than 80 nationalities currently employed with QR.. In my opinion don't listen to people's rumor and go for it ..

Good Luck :)
