Steady ladies! There's truth on both sides.
PPRuNe Towers has pretty much hit the nail on the head, except that, when it comes to MCC, type ratings, etc., most airlines just want to keep their costs down as much as possible. As long as wannabees are prepared to pay for their own training and the CVs pile up on the Chief Pilots' desks they'll screw you down as far as they can go.
Type ratings run to 'generic' SOPs are about as useful as a chocolate teapot. Type ratings run specifically for the airline are what you want but, you gotta hand it to them, some Low Costs are even getting recruits to pay for the type training they would otherwise have to fund and making a profit on it. Not only that, they don't pay you till line training is complete and sometimes that line training takes a loonnnnggg time.
The MCC course is so short its not ever going to be more than an introduction to two crew operations and it doesn't really matter if the sim is jet or turboprop, I'd still choose a jet, though. Jet Orientation Courses run the risk of starting to teach what should be taught on type conversion. Unless they are carefully controlled by the customer airline they could end up adding to their training costs later on when bad habits have to be 'untaught'.
As to the chances of getting a job, the sad truth is that an awful lot of it comes down to luck. Airlines will pick up the top 30 or 40 CVs on the file, select 20 candidates for interview and employ 5. You have to think, is that Jet Orientation Course that cost me thousands of pounds actually going to make that much difference, or would I be better off buying the 'How to succeeed in aptitude tests' book?
Who do you work for moggie? You keep saying 'us'.
