My friend once interviewed for a low level position at a well known startup company. He passed HR, took and passed competency tests, passed interview by future coworkers. Last interview was with manager of the team who happened to be a young woman who was a brilliant coder.
He didn't get it. He was sure that her expression changed negatively very slightly once she saw him on the video conference. My friend is quite sure it was due to either ageism or subtle racism. He is not white.
He's moved on but it confirmed to him fair is not a word he believes in anymore.
