One thing about having people who are trained is that the Germans are probably a bit more strict than the Anglos about whom they consider trained in a given field.

I've worked in the UK, where a history graduate can learn to be a derivatives trader. An engineering grad can with little problem get a job coding software (I did both of those jobs with a MEng).

Contrast that with my experience in the Germanic world, and I found the only place that ever asked for my degree certificate. My German friends have degree titles that are pretty much their job titles. I met people who were out of work, and when asked what job they wanted, they responded with a pretty narrow range of jobs fitting their degree.

Recruiters also seemed to take buzzword bingo more seriously, whereas London recruiters seem to be happy to put forward someone who says c# is like c++. Not without its own issues, but if you have a skills shortage, maybe take someone who is close enough?
