In other words JAR-OPS CRM is nice to have but not as needed as MCC for a career start
Don't think so. The CRM course is a part of the Operator's Conversion Course under JAR-OPS 1 Subpart N. Even if you were to complete some kind of generic CRM course, you would still have to do the operator's course, so there is absolutely no benefit - forget about it.
MCC courses tend to be “generic”
MCC courses are
required to be generic. If there is any technical (type specific) element to the course other than the checklists and SOPs, it is not being conducted properly.
MCC courses should include 30 hrs classroom and 20 hours FNPTII (SIM)
The MCC course comprises 25 hours of theoretical knowledge training and 20 hours (modular course), 15 hours (integrated course) and 10 hours (if combined with a type rating) of practical training in a FNPT II or flight simulator.
So, to summarise - Forget CRM, it's not necessary. Concentrate on MCC (multi-crew
co-operation) and, as you have been advised, choose your training provider carefully, just as you would for any other course. The quality of training is far more important than the FNPT or sim that is used - don't be suckered into a second rate course just because it's done on a 737, A320, DC10, or whatever.
