I discover this exact set of text on multiple companies' HR postings:
"We don't look for individuals who fit the culture, but those who will continue to add to the culture.
We encourage everyone to apply, especially those individuals who are underrepresented in the industry: people of color, LGBTQI+ community, women, individuals with disabilities (both seen and unseen), veterans, and people of any age or family status. "
It almost seems to be an exact copy from one playbook though these are on a number of different small companies' websites. My first guess is that this is taught in industry seminars to HR, and it feels like a religious creed.
However, what happens is the exact opposite of the stated intent - they screen out white American males, as I learned by hard experience. See comments below.
A buddy of mine is boss-level at a international finance company. He says that every new job has a requirement of interviewing at least two women/minorities (basically the nfl roony rule). If they don't find any good candidates they have to get a waiver to hire a white male. They can't keep women on the payroll because the whole industry constantly poaches women from the competition.
