In deep corporate America, there are plenty of people who have virtually no responsibilities beyond a few basic configuration tasks. They are still unable to perform many of these tasks without significant help from coworkers. And we cover for them.
Every incompetent coworker I can think of was a man. I do not think this is confirmation bias, I think it's basic statistics, because most of the engineers those employers hired were men.
I don't know about corporate America in particular, but corporate anything is a big pile of useless dipped in incompetent, where all the work is done by contractors who are also useless and incompetent. Because there is noone in the damn org that knows how to hire a competent techie in the first place.
So for me the OP's experience is more simply explained by working for an organisation that doesn't know how to hire engineers, not anything to do with diversity drives.
