I don’t understand what is wrong with hiring someone the interviewer likes. I can see there may be racism, misogyny etc at play here. But setting that aside for a second, if people like each other, all other problems can be solved much more easily.
Good intentions fail at some point, even when people have the best of intentions. Being distracted. Trying to do too much. Whatever. Where possible it’s better to design the environment and system so that the right things occur (or are more likely to occur) irrespective of an individuals good intentions.
So yes, you’re right!
