> Why is (non-technical person) interviewing me, a full-stack engineer? > "Don't hire. Brown guy didn't smile enough. Total jerk." It's possible to do the soft skills, personality and culture fit section of the interview really really badly, as in the racial bias example that you gave above. That's not the same thing as asking why it exists at all though. You could say exactly the same about the technical section, e.g. "don't hire, Brown guy misplaced a semicolon on the whiteboard". And yet a technical interview still needs to exist, has value when done with some fluency. Hiring well is hard. At least two people doing each stage of the interview is supposed to mitigate this bias. How well it works is other matter.
