I'm not sure if meaningful correlations can be made here. The percentage of Black employees could vary due to loads of factors. Geography: companies in areas with higher Black populations likely have more Black employees than those in areas with lower Black populations, with all other factors equal. Line of business: "Tech company" is a very, very broad category. Plenty of tech companies have majority non-tech employees. Amazon has much higher overall representation of Black employees, though it (in)famously does not break down representation by role.
