they are starting to do better, but from folks i know who have gotten offers from Amazon/Netflix/Google/Apple/FB, Amazon is consistently 10-20% less than the top (usually FB after several rounds of negotiation..)
I believe Amazon significantly increased their offers last year. FB was one of my other offers and they couldn’t match my top offers after negotiation, so I just declined. That being said, it is possible that a combination of my location (Seattle) and career stage (upper side of Senior level) are at play here.
