Maybe I’m just getting old and cranky but “too much experience” as a reason for not hiring someone just sounds like boardroom speak for : we want someone who doesn’t know their value that we can manipulate into overworking themselves for subpar pay while constantly dangling the promise of bigger and better things to keep them on the hook for as long as possible. 

People in positions of power don’t much care for those who know their worth and carry the experience to be able to advocate for themselves.
