Everything matters. Given two more or less skilled candidates, I guess if one looks like Brad Pitt, well, that's something no? Or if someone has a really nice voice, that has to count for something. Perhaps the company is thinking in terms "oh, candidate 2 has a magnificent voice! If we ever present tech conferences, he will do great!"

This is not a world where "only your brain" matters. If you have brain and a decent surface (i.e., face, body, voice, manners) then you'll beat the ones who "only" have brain.
