Many who were competent and delivering got shown the door while useless people who do nothing survived and failed up. Majority of Directors/VPs don't know the ABCs of engineering of managing people - they are just good su-k ups, liars and back stabbers. Bad behavior and failure gets you promoted - IDK. Note I did not say everyone, there are brilliant, kind, great leaders who are worth every dollar they get paid, but they are the few angels around.
