The median time an employee stays there is now under 2 years. Clearly Amazon isn't hiring the calibre of people they need.

Well it's been a while for me, but "we just do what the other guys do" was the impression I got when I interviewed there. Except they added a lot more "here's a terrible workplace situation, how would you handle it".

I'd love to know what their research is revealing, beyond questions like the latter case being emphasized.

Yeah, sure. We got all these smart people in a room. They can't be wrong. /s

I'd actually say the opposite. These researches are probably making hiring worse.

How many formats have they tested? For AB testing to work, A and B should be at least distinguishable. Every single tech company has the exact same process. Sometimes even the same questions. And that applies even to any point in the ladder. And to every single role as well. (Only PM interviews are slightly different but in tech companies even they have to go through the same process until that differentiating round)
