Right, if you're a big company you can more easily afford to have false negatives than false positives, so why not add knife fighting to the list of qualifications, just in case?
Hard disagree on this. Large companies can't afford false negatives because false negatives can hide out and move from team to team without detection. At a small company if the same thing happens it means leadership is incompetent and you have bigger problems anyway.
At the risk of over-explaining (hopefully) obvious satire, I'm considering a "false positive" to be someone who was hired who should not have been, i.e. the hiring process gave a positive result that was wrong.
Large companies can and often do afford sizeable percentage of workforce making zero to negative contributions. This would be devastating for a small team with a finite runway
