I've heard of caste discrimination during my second internship (in Europe, not in the US), so quite early in my career, from a "Yada"(??? Correction would be welcome here), concerning another collegue who came from a lower caste and how he was "lucky" not to be in the US or working with a "Bramin" or another elitist caste.
