Don't go to Qatar just because you are tired of waiting for Emirates. You really will regret it hun. The day will come when Emirates will be recruiting in full swing again. And on that day, you dont want to be stuck at an airline you didnt want to be with but took cos they were your only option.
Look into Qatar and research research research. Every airline has good and bad to it so make sure you find out as much as possible about both.
I know you say you wouldnt mind the curfew because you dont want to be out past 10pm anyway, but wouldnt you like the option? Wouldnt you rather be at EK or EY and still home for 10pm because you want to be, rather than because you're forced to be?
If you can honestly say that if you were offered the position of both Emirates and Qatar and would seriously consider taking Qatar, then go for it! But if you're only thinking about Qatar because they are the easiest road to becoming CC at the moment then I would strongly advise you to hold on for a few more months and wait for EK or EY.
