The problem is that employers in the USA, unlike European countries, make themselves liable for discrimination claims if they ask questions like "Are you male or female" , or "What is your race?" before or during the interview. It's only when the person is hired so they can get this information. This means that there is no good metric to say how many black people, Females, or whatever other protected class, is applying for jobs and/or getting interviews at tech companies. Facebook cannot say things like '3% of the people applying for us were female, and we hired 80% of them' -- they can only say 'We hired N females' or 'N females make up our workforce'. I work for a large, international tech company, and we are gung ho about diversity -- but we just don't get very many candidates that express interest in doing the job that fall outside of the industry majority. I've interviewed 2 women and 25 men in the last year, and we hired 1 of the Women. Based on that , people will say 'hire more Women', and I'm all like 'What Women?'. That's why this is such a great focus point for social justice bullies. They will never be wrong that the tech industry doesn't hire many minorities, and you cannot prove that it's because they don't even knock on the tech door without making companies targets for lawsuits.
