I agree that it is (probably) highly unusual that foreign graduates immediately gain employment in UK Companies (at least the 'high profile' ones) They would usually, as has been mentioned, spend their last few years of training at a UK Upper School, either through audition, or being 'spotted' at competitions and would then, through the school, be invited to audition/join a company by a visiting AD. Do RBS, ENB or Northern even hold open auditions ? (I may be wrong, but I don't think so)
