I heard a few already received a "No thank´s" from TUI last week, although these guys barely met min requirements.
If there is any truth in the "800 application" statement, that means around 10% will be called for stage 1, and roughly 35% of these will pass on to stage 2. Out of those only 30% will be selected. If I go all the way, I´ll consider signing up for a few lotterytickets!
