I just met someone who went through the CAE program to got hired with FD. He had UK CPL with a frozen ATPL, and had recently completed a MCC course in Amsterdam.
The candidates can either pick the EASA Type Rating Course (which he did) or the FAA Type Rating course.
CAE does all the training and Fly Dubai sends one of their examiners to observe the final check-ride which leads to the type rating. It is very high pressure because not only are you taking the check for the type rating but it's also a job interview to some extent. You must be able to fly to ATP standards for EASA or FAA as the case may be. Not being able to do so and failing the check-ride means you will not be considered for FD.
If you do well, they call you for an office interview and then hopefully a job offer. It's an expensive course (probably $20,000 or more) and a gamble in terms of job prospects. This guy got hired and was glad that he did the course. Everyone has to make their own decision.
