My friend works there and said that virtually everyone gets dropped a rank on the way in. It’s so common that people commonly introduce themselves as “I’m an X but pre-Amazon I was an X+1”.
The extreme version of this is being CTO as a startup of 10 people vs CTO at a company of 10,000.
There really need to be laws with teeth about false advertisement from both employees and employers so we can skip this sort of non-sense false advertising.
