I get the sense that, because of Amazon's roots as a bookseller, they still like to optimize for people who are a bit more well-spoken and well-read, compared to other FAANGs. At the executive level, PowerPoint is banned and all meetings start by reading a well-composed multipage memo.

Being able to tell a great story might not be highly valued at most orgs, but I think it's part of Amazon's culture and something they desire in their skilled positions.
