Same. No one even brings up caste at all, except very rarely in the context of someone's parents back in India wanting a spouse for their child overseas (for arranged marriages) to be of a similar caste(like date/marriage racial preferences in the west). Things are changing fast in India and that is becoming rarer as time goes on.

Very strange that it comes up a lot on HN for some reason. I'm not higher caste and I never felt anyone has ever mistreated me in professional or personal life.
