You do not know how many good candidates are filtered out because you have bad hiring practices.

I was tricked into a code golf challenge which was a hiring test. The result was good I was surprised that slacking off could get me a nice discussion, and the company got to pitch their positions. I've never done a hacker rank thingy for hiring and probably never will, I loathed them in school. They do not tickle my mind nor can I scratch my itches with them.

I know this sentiment is shared by many high value employers I've had the pleasure to work with.
