[Rubinsalamander]

As long as they can fill open jobs with somehow suitable canditates they have no real reason to change their established process. They dont need perfect but good enough. So even if they miss some good canditates it doesnt matter and they dont know which person they missed in hindsight.

If they have problems finding qualified workers they are much less strict with requierments and more creative

Another reason to prefer easily measured established values like experience is to justify yourself against higher ups if something goes wrong
