After flying the airbus for several years now, I know a jet orientation course cannot determine your ability to properly handle a 737.
The type rating is demanding it requires you to know the expanded sops and stay ahead of the aircraft .
Most of all your over all aviation experience and decision making will also be judged, technical knowledge and confidence is the biggest problem I am seeing on the line with ab initio. That being said it's not impossible but this doesn't mean fly dubai is going to accept you
