Yes my friend, friend went to a interview with Qatar recently.. And was told "sorry we can not process your application for Qatar for now since you are working for MAS." I friend was then told off the book.. that I a letter was sent to emirates and Qatar etc.. not to poach cabincew from MAS.
But Hey... since no one received no notice about this situation.... GO FOR IT... ALWAYS look after NO1 .. since MAS is not looking after you...
Live in a way that is full of life... for yourself, for your loved ones, for your friends
