Big mistake !
Well i worked for QR, and i could not take it, i resigned. Believe me if you go there you will regret it, try to go for another airline in the region, etihad or emirates. Think about it a lots, cause people don't stay in there even for training. The management is strict, you will have the worst days of your lives. That is my advice, but if you don't mind it's up to you. I have no friends left in there anymore because everybody resigned.
Take care !
