I ran into this quite a few times when looking for AI companies. They often put it prominently in the About Us pages or their annual report. Some organizations were also giving grants or mentoring only to minority members.
That DEI makes hiring decisions partly based on race, gender, sexual orientation, etc. means it shouldn’t surprise you at all that someone mentions it as a hiring factor. If they hired X non-whites, then up to X whites may have been rejected depending on the makeup of the candidate pool. That’s just how systematic racism works. It should be abolished.
