This was a fake wanted ad but I routinely receive recruiter emails invidiously discriminating on the basis of age by specifying a max experience level.
I have heard the term "too senior" far too many times.
In my modern experience though, no one would dare put up such a wanted ad, while one asking for a person of color, minority, or some form of diversity token would be perfectly okay. So I guess it is edgy after all to say "White CEO Wanted", but not for the reason they were going for.
