Who gives a f about the comp plan? I'm on 5/15/40/40. The first two years are cash with bonus and then the stock vests in lieu of the bonus. I am making $275k and the stock has gone up 40% since I joined. And yet, if I stay through vest, it's like a $25k raise (9%). Why would they be incentivized to PIP me?
Plenty of people work here and get filthy rich. They stay because they create immense value at scale.
Sounds like sour grapes to me. I doubt you'd pass our interview.
