Before tech I did a stint in recruiting. We had a client demand only "white sounding" names. We ignored that and provided any qualified candidate. They complained because they mistook the recruiters name for an applicant. We fired that client the same week. It was a truly disgusting thing to be asked and I'm glad my company made the right call. Any future client that asked that was immediate grounds for client dismissal, i.e. didn't require management approval.
