I'm with Ford Cortina on this. There is no point in spending vast sums of money on the MCC simply in order to get into a jet FFS.
Any handling skills you learn on the MCC are highly perishable. In 3 months you will have lost them, so it's common-sense to delay spending your hard-earned or borrowed money until you have actually secured an interview! At that point it IS worth spending money on a Sim Assessment Preparation session on the Type on which you will be assessed.
The MCC is a good idea in principle but sadly FTOs have twisted the emphasis of the course in order to make it more marketable to newly licensed, eager and impressionable pilots. Yes, it's more exciting to go from the Seneca you flew on the IR into a 737NG but it's an unnecessary luxury. The course is supposed to be about CRM, not getting a taste for flying glass cockpit jets.
I speak with the benefit of hindsight, having completed an expensive MCC, passed a sim assessment with a major Airline, and passed a 737NG TR in the course of the last 9 months. Given my time again, I would do the MCC at an FTO with a good reputation on a FNPTII or old jet type. I can honestly say that the MCC had NO effect on my ability to get the job.
Just my 2 cents worth.
