Sadly, the ex-Accenture people who get exec jobs in-industry didn't learn from the PowerPoint overkill, either. I work for a company completely run by ex-consultants. Who spend all their time sharing PowerPoint decks. The next layer or two or three of management spend all their time building those decks. We get called into meetings to talk about upcoming meetings, and asked to give the content for various slides in those decks. We recently had an influx of new leaders and now there is political infighting over whose format of decks and slides is the right one to use.

I clearly am also being snarky/sarcastic. They do know more than this and they do more than this. But there is a some real truth to the matter, that consultants never quite lose that idea that their job is to do snazzy presentations, and that ends up getting more focus than delivering product.
