Blatant nepotism among various groups in Bellevue

I have worked in Seattle a few years and have plenty of “friends”* so I can speak on this. There’s blatant nepotism among the various groups (Asian women, Pakistani, South Indian, Chinese, Russian, Jewish, Europoor) in tech.

They have created a nepotist monopoly among every large and small team they become a part of, and PIP everyone else. They will only train, promote, and hire those belonging to their group and see those not a part of it as strangers that cannot be trusted*. These groups of people are very tight knit populations and see other people in it as brothers and sisters. If they were to choose a candidate to hire and they chose a person not in their group over someone who is, they will be shamed by their family and community
