This setup is unique to Amazon and is not at all common everywhere else. Almost all others give refresh grants as long as performance isn’t in the bottom 5-10%.
Refresh grants for mediocre performance are mostly a Google/Facebook thing.
No, refresh grants (around 25% of initial 4-year grant) for median performance are the norm. As far as I am aware, this is the case in all FAANG except Amazon.
Have you worked at Apple or Netflix? Since that’s what we’re talking about.
