My standard answer to this question is "use the search function" but I'm in a generous mood this evening
There's a technical written exam that a brush up of your ATPL subjects should cover. Basic aerodynamics, swept wing, terminology, performance terminology (TODA/TORA/LDR etc).
Sim seems to be the Embraer 145 these days but in the past that's been subject to sim availability.
Scenario questions along the lines of what would you do if............passenger wants to turn back, baggage won't fit and my personal favourite, the captain arrives at hotel check-out the worse for wear
Seriously though, a search will tell you the latest feedback if that's what you
really want.
