If 6-30% are failing year after year after year, you can't blame the interview process. You could blame the leadership failure that didn't fix the interview process, though.
Really it's indicative of Amazon treating their employees as disposable. They have enough employment market power still to attract enough great talent to burn through individuals in 2-3 years. Eventually they run out of meat or they soften the process.
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?
