Very tangentially, the "Snakeoil Salesman" reminded me of a candidate I once interviewed. For an hour and a half they showed a dozen codebases cloned off github, explaining basically what the README.md explained without actually saying anything of substance, while using a lot of trendy buzzwords. Whenever we tried to probe concrete details they'd immediately jump to another project. It was the most infuriating interview I did by far.

My previous boss would hire that person, and when unable to perform then promote them.

Outlining the rich diversity of a typical corporate IT shop.

I’ve never seen any of this, in my decades in this business.

I am more interested in why people write crap like this.

Note how nobody actually does any work.
