One company I worked at in a major US city allowed individual teams to perform their own hiring. The division I was in had employees mostly from outside the US, and the autonomy given to each team led them to form their own to ethnic enclaves. There was a team of Indians, Chinese, Koreans, etc. When I first started, I couldn't believe it. That doesn't happen merely by change, at least not that pervasively and consistently.

It sounds like this is occurring everywhere.

I’ve seen this at the two FAANGs I’ve worked at as well. The company may be diverse but teams are homogeneous.
