Even teams that work with overseas teams tend to funnel that through several people or the like (this is universal). Even "english only" companies in Tokyo will still just have a bunch of docs/convos written in Japanese when the team compositions are not uniformly mixed.

There are of course aesthetic/logistics reasons behind "code the stuff in English" (if only cuz your code is going into an ASCII codepage, and ... yeah, sharing). But the language used in teams is pretty company-culture dependent, and "we do all of our work in English" lands in a very restricted set of companies. Probably Finance is the one where that culture is there, but most tech companies.... there are higher-than-average english language levels in these places, but if there's no other English-preferer (foreigners, but also returnees or people who just like English a lot) in the room?
