You can only get the rating by applying through one of the TRTO's they will pull you through a normal selection process. This means that you are lucky if called upon as there are a lot of people out there applying. To go somewhere else for a general rating does not help you as you will have to redo it on their procedures..
It is not iffy to go FAA Typerating to JAA Typerating with 0 hours it's impossible....
Yes work there.. and happy
