AH, the selections done by the training providers is exactly the same as a normal job interview and selection by the airline. The interview is done by the airline Mr Dooney. This means you are as lucky if called upon as for normal selections.
Once in the system and selected you are basically 99.9% sure of a job. This all means that they will not select and train just to sell you a rating.
I believe that Gecat and CAE are full for this year but you can better check with them.
