Take the first paragraph for instance:
> They are told to forget the “poor habits” they learned at previous jobs
I don't recall anyone telling me this
> When they “hit the wall” from the unrelenting pace, there is only one solution: “Climb the wall,” others reported
I don't recall hearing either of these phrases used.
> To be the best Amazonians they can be, they should be guided by the leadership principles, 14 rules inscribed on handy laminated cards. When quizzed days later, those with perfect scores earn a virtual award proclaiming, “I’m Peculiar” — the company’s proud phrase for overturning workplace conventions.
The leadership principles are repeated pretty frequently, although I think most people take them with a grain of salt. The quiz is called 100% Peculiar, not "I'm Peculiar". I don't recall it being about leadership principles at all. I recall it being about things like how Amazon doesn't delete negative customer reviews because the company sees it as being in its long-term interest for reviews to be trustworthy. The other thing on the quiz I remember is that Amazon likes to use informal language with customers, like "Where's my stuff". [Edit: I should also point out that it's not a mandatory thing and nobody cares if you don't do it or don't do well enough on it to get the little badge on your page in the company directory.]
