If a felon applies, you hire someone else and never tell the felon he was rejected because of his academic credentials (racist), his criminal history (racist), his poor interviewing skills (racist), because of his unprofessional attire (racist), his tattoos (racist), or because he pulled a knife and threatened your receptionist (racist). Having made the mistake of giving helpful advice once, early in my career, I never again gave an interviewee any feedback on how to improve the resume or their interviewing. It's not worth the risk. You don't even say that someone else was better qualified (that's racist too), just that a different person was chosen or even better that you decided not to fill that position.
I've watched the HR dept do it.
They passed a law against requiring a photo on resumes, and the ‘diversity’ crowd names their kids Shaqueilla and Jumal? Clever indeed.
