MY MCC was on a king air so there will be some slight differences, but basically you will be introduced into the world of cooperation, proabably also autopilot. Thats basically the most you will learn is how to do your job in cooperation with your fellow pilot, ops staff (becasue when you divert its no longer your choice but more like that of the company to say go here)
But do enjoy your self, its easier than an IR and you should find it a lot less stressfull
