Their interview process, while thorough, isn't failproof. Additionally, it primarily assesses candidates at entry, overlooking potential changes in performance that may emerge after a couple of years within the company.
Of all the FAANG, I almost admire Amazon for chewing up & disposing of their white collar work force the same way they do their blue collar.
The other guys are all pretty bad to work for at the bottom non-SWE tiers, but have cushy SWE adult daycare office environments. At least Amazon treats all their employees as disposable?
I love that description
