That’s what another guy said, and I believe you both.
But all I’ve ever worked with were dark Indian guys in tech.
Never saw a light one out of dozens.
Is the white area more rural and less apt to end up in a US investment bank?
Yes, the smartest, technical Indians are often the darkest - Tamils, Telugus, Kannadas, high caste Bengalis, a great number of southerners. The exceptions are often Sikhs from the Indian Punjab, like Haley, who are light skinned northerners.
Indian peoples specialize.
And they can surprise. I have met short, dark Sikhs.
