In 1976 I was talking to a recruiter. He told me very bluntly that if I was a woman, black or better yet a black woman, he could get me interviews with any Fortune 500 company I desired. But as a white man he’d do the best he could, but not to expect many large companies showing much interest.
Over the course of my working life, I worked successfully for a number of smaller or local companies and did quite well, but I was never hired by a large American or international company.
