It's weird to see that stuff follow over to other countries. At my old job, 90% of the software team was from India, and at times there was a palpable animosity - eventually it was explained that there were two different castes represented in the team, and the more vocal engineers still took caste very seriously.

(Unclear why this sub's weird downvote train arrived 6 hours later for an innocuous comment, I suspect a brigade is upset about its caste situation.)
