Interestingly, I grew up in India but have no clue what my caste is. I could probably ask my parents and they'd know but it has never come up. Religion and sub ethnicity came up a lot more often while growing up. Funnily enough the only ones who have ever asked me about my caste were white people.

I had always assumed the caste system was a thing of the past but looking at how it's still present even at companies in other countries, I imagine I just grew up in a bubble.
