re:just it is easier to get a job with them if your skin is white
Not sure this is what they are saying.
Whether that is the underlying cause is another matter, and fundamentally applies everywhere, not just Facebook.
Diversity policies go against sound business practice. If you have to hire less competent people because of their skin colour, that's still discriminatory (just in a way that is inexplicably ok to those insisting on diversity policies). A business full of idiots is a business full of idiots. Doesn't matter that diversity regs have been met; that business is doomed.
The devil in the detail is surely the comp-sci graduate racial/gender distributions, and the applicant racial/gender distribution. If 97% of graduates/applicants are white males, well... doesn't take a genius to work out the hiring distribution will be predominantly white males.
Yet if 97% of graduates/applicants were minorities/female, would we even be having this discussion? Would Facebook get called out on it? I doubt it, because that doesn't fit the PC brigade agenda.
Hiring decisions should always and only be about competence, never about skin colour, gender, sexuality, age or any other bullshit. Diversity policies be damned.
If you're best for the job I will hire you.
If you aren't the best for the job, I won't hire you. End of. Entirely based on competence. PC brigade can bite me.
