Truckflyer I agree with you but unfortunately companies want the product (cadets/low hour pilots) as ready as possible to fly their planes. I perfectly know a mcc course is not a type rating and any multi crew aircraft would be fine for the job, but nowadays if it is done on a Boeing 737 sim for instance, it gives you a deep introduction about how a jet plane works, the correct flow of checks and so on, making a cadet more "ready" for his initial type rating. They want to keep the risk factor as low as possible. Netherless, most interviews are now conducted on 737 or 320 flight sim where they test your hand-flying skills. Thus, previous experience where you have learnt how to deal with the inertia of bigger jet planes during manouvres and how to manage higher velocities could be useful for a pilot facing his first interview.
