> The interviewer seemed to have some sort of implicit bias - I think she really didn't think that black people should be confident in a professional environment. I can't imagine that she would have taken similar offense to a white guy asking those sorts of questions.

Well that's your bias though right. I mean maybe she was just intimidated, stupid, and/or human...

I just came out of a situation where a guy on the train was looking at me with the most disgusted look possible. To the point where I was checking myself in the reflection to see if I had a booger or something. Being white I have to assume he was just a weird dude.

I honestly can't imagine what life is like in the shoes of a minority, but I wonder how often false positives show up. I mean you are assuming the other person is a racist, which is a heavy accusation.
