Not that I know of. I did MCC/JOC at Simtech (Dublin) where they used to do their assessments and I was still turned down at the interview along with 6 other guys (we were 8 that day, only 1 passed). I guess the thing with MCC is really to have the certificate in your hands, it doesn't really matter what type you did it in or where, you'll have enough time to worry about the specific plane once you get to your type rating.
