No such program is likely to be worth the money, unless you are independently wealthy.

It will not help you get a job unless the school has a specific bridge agreement...in writing with specific airline(s). If there is such an agreement, get success statistics IN WRITING. Many of those programs will guarantee an "interview", but the odds of actually getting hired may be slim to none. Caveat Emptor...

It may make training easier, but the vast majority of new-hires complete training without any extra prep. Also if you are so marginal a pilot that you NEED the extra prep to complete training, then your chances of completing captain training and eventually major airline new-hire training are not so great...
