For the converse, work at someplace like a university. Open positions are advertised (because legally they have to be) but the vast majority are given to insiders. Qualifications are almost entirely who you know and who they know. I would guess many government organizations are similar.

I have seen this, but it's still never competence based.

I really don't see anything preventing someone who's been catastrophically incompetent at every job they've ever held becoming CEO or heading a department. This might explain why cognitive ability correlates much less with earnings judging by NLSY etc. than in the past.

Anyway it's very far removed from the Peter Principle.
