I left the RAF in '92 (yes, I know - KOS) with an ATPL gained with exemptions and was somewhat dismayed to read the back pages of Flight which contained several adverts from major carriers (including Cathay) stating that all applicants must hold an ATPL - gained without exemptions. I have no idea if that is still current practice but taking all the exams anyway if time etc permits is not a bad idea imho.
Good luck to all potential job hunters.
