My dad had a recruiter delete his PhD from the education section. During the interview a topic related to his thesis came up, he mentioned his thesis and the interview was over because "we don't hire people with PhDs"
1. Having interviewed otherwise similarly qualified recent graduates, those with PhDs absolutely were worse on average at writing code[A].
2. Having a PhD raises the salary you can get at other jobs (less true today then 25 years ago when it happened, but still somewhat true), so if the job isn't paying particularly high rates then they either worry about retention or quality (i.e. you can either get a better paying job elsewhere because of the PhD or you can't despite the PhD, neither of which bodes well for the company hiring).
#1 didn't really apply to my dad since he had over 10 years of industry experience at that point, but might be the reason for the policy.
A: I don't know why this is so. I suspect it's a combination of factors; those with good practical skills may be lured away from academia after one of their previous 2 degrees and never get a PhD; the PhDs looking for industry jobs are already those who were disqualified from academia for some reason? I never pursued any education after my B.S. so can really only speculate.
