Yes, that would be another example. But, I think, a different sort of example. Let's suppose that candidate A comes across better than candidate B in interview simply because of widely-shared prejudices affecting the interviewers. For the kind of job you describe, that (rather horribly) means that candidate A probably is better able to do the job than candidate B.

(It might well be that the best thing overall is to try to stop people in that situation favouring A over B on account of prejudice anyway, in the hope that over time this reduces the overall level of prejudice and everyone is better off.)
