Well, white and European descent is quite common in Berlin and Germany. That's much of the population there and around. Still, there will be some diversity with people from many European countries, since EU members can move freely in the EU and can easily work in other members states.
Not many women in German software companies is also quite common, unfortunately.
You're getting downvoted for the throwaway, but I had the same thought. Amazing to see such a complete lack of diversity, and sad to see it being ignored by almost everyone in their responses.
I don't know. Just listening to the many different accents in the video, there were people from many different places. All of us have different stories, even white guys. Diversity is not just about skin color, although some seem to think so.
There seemed to be plenty of people from lots of different parts of the world. If you were actually concerned about diversity maybe you should be looking more than skin deep yourself.
It is less than 10% in Berlin and most of them are second or third generation descendants of immigrants and most definitely white Germans "mit Migrationshintergrund".
