jafar...I suggest you read old forums re conditions and personalities at QR. As for the previous comment I suggest it was probably management. I work elsewhere in the Gulf and my friends that do work there say that the picture is not brilliant. However, if you are unemployed it is better than nothing.
One thing I will say though is that Doha has improved greatly and should be a reasonably good place to live. Previously it was a little sleepy place but it is developing quite nicely. Pity the airline has not developed as nicely though.
Have a nice day
