The company'd be much better off if he applied the same standard to the development side of the company, which has an average tenure of around 12-18 months for developers (more senior devs tend to leave more quickly than junior devs).
When I was interviewing for jobs to get out, I encountered close to a dozen ex-Amazon folks... none were at all surprised that I wanted to leave, and one even said that he only joined Amazon for the resume pad.
My experience was basically that they hired me because "senior developers should be good at wading into bad code" rather than for anything vaguely resembling the sorts of engineering tasks that they grilled me for during the interview process.
Most of the software I got stuck with was a nightmare of bad design and rushed hacks. It was also a technological step backward from a government contracting job.
And then there's the problem of supporting all of that crap...
And the benefits aren't all that good, to boot.
Most of the developers I've talked to who worked there didn't like it, and the more senior they were, the less they liked it.
