I have a friend and former colleague who was for many years a FE in the RAF. He then left and did his FE licences and got a job as a FE. He subsequently went through pilot training, paid for by his company and only had to do the Nav writtens and Air Law. It would seem to me that he did get relavent exemptions. i.e. the stuff that he had already covered as a flight eng.
His company have also given him credit, albeit not much, for his experience as a flight eng.
