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...
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.
They could start with the vesting schedule for one.
Maybe have competitive salaries with FB & Google?
