From what I can gather the reason why there isn't a definitive sim detail for Netjets is that it changes depending on what sim they can get.
However,
Expect a SID, tracking via an NDB or VOR, approach to a hold, then NDB or VOR approach (or even something else). All hand flown, all raw data.
You'll find out the speeds, thrust settings, V speeds, flap settings, wx and location on the day.
You aren't expected to fly that machine perfectly, you are expected to show learning potential, common sense, basic IR skills and good CRM/communication skills.
