I grew up in urban India and my experience with caste system is the same, never really experienced discrimination personally but I know of it being widely prevalent in the country.

This scene from an Indian movie I saw recently made me realize that the caste system is not just prevalent and absurd but also has a very complicated hierarchy built into it. https://www.youtube.com/watch?v=r4N98tQsp64 (<2 min, with subtitles)
