Of course this is a rumour network, so you can never trust anything 100%. But there has been various posts talking about FlyBe not picking non-recommended OAT graduates from their database and there's never been anybody denying that fact. Ian Cheese has always said that they take both integrated and modular students, and you'll find many posts on PPRuNe from modular students who got the job at FlyBe from applying by email (in the old days) or online. But they never seem to be OAT modular students!
I apologise if it's not true, so if you're OAT modular and got the job by applying online, please post!
