Personally, I would like to think that any "professional" pilot would have the natural or learnt capability to fly a basic sim detail in any commercial cockpit. I know that people do not understand the aircraft that they are completing the sim ride/test/assessment on BUT it is the eye - scan rate - brain processing procedure - hand to control input - desired outcome that matters. No matter what aircraft one has flown as a "professional" pilot, manipulating any aircrafts controls to achieve a safe and desired output should be the basic fundamentals of any pilot.
An engine failure in any twin requires the same procedure of hand eye coordination. Scan rates and VOR tracking is the same in any aircraft. Circuits would need to be briefed and understood I would agree as jets fly wider patterns than props, but being flexible and adapting to changes is part of a pilots specialised abilities.
I had never flown any of the EK fleet types before I did the EK sim assessment and yet it just required concentration and adaptation of known skills to achieve success. To me, I for one am glad that recruiting standards are not lowered as it should be expected that any pilot flying a commercial aircraft today should be able to perform these manoeuvres. Emirates is not training "new pilots", it wants to train commercial pilots to fly a new type and I believe that if a pilot displays "minimum acceptable commercial piloting skills" then they have a chance to further develop those onto other aircraft types.
Good luck to those who make it through, to those who didn't sorry but in fairness it was in your hands and no one else's.
