Can anyone elaborate on this? I assume Amazon could trivially build an internal CCC, and I'm at a loss how their internal tools would be less accurate than a 3rd-party scraper...

Anyone who could elaborate is NDA'd.

In general, though, Amazon is always kind of starved for engineering resources. It sucks so much to work at in so many of its teams that it has a colossal retention problem and, one would expect, the corresponding level of technical debt.

Maybe if they made being an engineer there a winning proposition...

They could start with the vesting schedule for one.

Maybe have competitive salaries with FB & Google?

I genuinely do not understand why they don't do this. Bezos either has some sort of master plan relating to a high-turnover staff model or is delusional about the true culture underneath him. I don't know which.

Trump's using the same model fwiw.

You would think with internal data that internal tools would be better, but time and time again they're not.
