Here's some information.
Read the article posted in post 233, it's an eye opener and also very true.
I asked a Qatar crew member about it last night and she was very reticent to answer apart from that they had been told not to talk about the article in question nor to answer any questions about the living arrangements in Doha on fear of dismissal.
Don't just look at a job go and look at where you will be living and what the lifestyle will be. Believe me it is not pleasant.
Please, please, please think hard before you pay out such large sums of money for a job that has absolutely no job security whatsoever.
Job markets will be moving in the near future, Qatar is not the only option out there, go get a job flying something fun before you go to the boring stuff.
