I agree, so upvoted. The most important question is: "Would I like to work with this person?". That is unfortunately unfair.

Given the power that companies have over individual workers, I'd say that a job interview should be treated as seriously as a court case. So yes, making it fair should be an explicit goal.

A company's goal isn't to hire every good potential employee, it is to hire a number of good employees, and avoid hiring bad ones. If Factorio wizards make good engineers, who cares if only 1/10 good engineers have even played?

Who cares if they are all white 23yo frat bros? who cares if no woman can get hired so long as the company makes hires it likes. Or gay, or Jewish, or whatever busy is in your selection.

I'm not asserting there's a specific bias in this particular interview choice, but I am asserting that if you were taking a fairly narrow part of the population you better be working damned hard that you don't have hiring biases that are not relevant to job performance
