Camel,
Hope you enjoy your visit to Dubai and are successful with FZ.
You would be surprised about the leave system. Most people get what they want out of it. Yes, as a new joiner after October you will get the left overs as that's when the bidding happens. As for PBS and weekends off, like you said it depends on the bidding. I actually try to work Fridays and Saturdays because I hate weekends in the city!
Good luck and all the best
