The strict social hierarchical dynamics of Indian culture is damaging to a lot of workplaces. 2nd generation Indians are great. The Indians that are from lower casts or from oppressed groups like Christians or Muslims are really great. But the higher castes are extremely insular, and treat anyone of any race poorly. This might be taboo, but every time I see a situation where there are multiple Indians in a reporting…
So here's the thing. I have no doubt that stuff like this does happen. An Indian friend (Brahmin, Indian citizen, has lived in the US for over a decade) has also seen this happen sometimes, and tries to avoid reporting chains with too many Indians down the line, even though it's unlikely he himself would experience discrimination (he just has no patience for ultra-political, back-stabby environments). But labeling al…
I have to say, though, if I saw an org chart with a disproportionate number of Indians (relative to nearby & similar companies, or other parts of the same company) I would take that as a warning sign.

It just seems unlikely that a whole bunch of cool, modern, forward-thinking Indians just coincidentally happened to fill a whole management chain.
Frankly, I'd think the same thing if a management chain were overly-dominated by any particular group, be they Chinese, white, or, I dunno, UC Berkeley grads. It's a sort of organizational smell. It just seems to happen more often, anecdotally, with Indian management, either just because there are proportionally more of them or because they're used to a more old-school corporate culture.
