It's Google, there are literally thousands of open heads at any time. If the white guy passed the hiring bar, they'd hire the woman, the "colored" as you put it, AND the white guy.

Then they'd offer them recruiting bonuses if any of their friends were good recruiting leads.

I’m not sure which of the colours is a problem for you but Google is 69% male and 59% white. Their stats don’t support your claim. https://diversity.google/commitments/
