Sorry, that people who speak their own language in their own country bother you so much.

That's just not true in many companies nowadays. E.g. in the automotive industry (which is 1/7 of the german economy) I have a growing number of colleagues who don't speak a word of German.

Well "growing numbers" vs. reall acceptance is quite a long way.

Possibly in Berlin, where is more alien friendly, to be able to get any job in English, in south, especiall south Bayern is quite difficult, even in IT ( which I really don't understant). Might be if all customers are in Germany, then there will be a gap somewhere, which someone has to fill and they don't really want or can.

In bigger companies ( like automotive, or even Siemens ), they do have customers and organisation from all over the world and English is the primary documentation and also common language.

I only wanted to say, that given a perfect candidate for a position, it might be rejected because it doesn't speak German.

Many startup companies in Berlin are English speaking as their daily operations.

The point is if the majority of people are native German speakers you take a major productivity hit moving to English, say 10% which increases your costs and demand for people.

Where are you looking? In Berlin startups often have english-speaking engineering teams.
