But these are not 'superficial' observations. People of Indian ethnicity are more likely to be the product of (tier B) Indian educational system (which is based on Brahminical rote memorization), Indian culture (always say yes to your superior), Indian incentive structure ("how many people are you managing?"). The last job I worked at, more than 50% developers on the floor were Indian (like either fresh H1b or intra-company transfers), so I noticed that I would get 'lost' in the crowd. A non-Indian person will immediately notice other non-Indian person, and ignore me. It wasn't their fault because most Indians on my floor never bothered to say 'hi' or 'bless you' or even acknowledge anyone who wasn't Indian. But then, I'd also ignore other 'pattern breaking' Indians (until, like me, they made themselves stand out).
