One of my friends had a story, where he was conducting a job interview with an American-born Indian teammate, and the interviewee was an Indian; when the interviewee went to the bathroom, she offhand guessed at the interviewee's caste, and then immediately felt mortified that she said that to a non-Indian and apologized. Just hearing that story secondhand was pretty wild for me to process!

In the US that is illegal, your friend should have immediately reported it to HR.

Not totally sure that "Caste" is a protected thing.

Several of the laws are broad enough to apply.

Last year I remember a news item linked on HN where some HR person flat out said that "caste" is not a protected category.

If you doubt the interviewer's integrity in making a decision, just remove him from the panel.

better to be safe than sorry.
