Well see you in ICN end of may
I´m there too.
My friend has been already there. Simulator is nothing special. They emphasize on good CRM, and one of the absolute No Go´s is to touch the FMC when you are PF in manual Flight.
Captains and FO Screening is pretty much the the same - The only difference is, Captain has to do an RTO and FO has to fly a visual pattern at the end.
If you have own ICN Charts and an 744 QRH, take it with you to the sim.
Interview is pretty straight foreward - only about 10 minutes.
Medical is little bit tough. They keep an eye on cholesterol, if you are over 200 you are not busted, but must reattend the medical. Also they test eyes a lot.
