Or any company with a low % of Americans. Many big tech companies and unicorns have a high immigrant %. There is very high cultural and background diversity in these companies despite low racial and gender diversity, (gender and race aren't useful metrics/proxies for cultural diversity in companies with high immigrant populations). Everyone on these culturally diverse teams all grew up in different countries and have different primary languages. As a result, they have very little in common and are less likely to have casual conversations with each other. People come into work and leave.
