So, that adds up to around $495K/year, or maybe $300K after tax. With $50K/year in expenses, you're left with $250K/year, or $1M over 4 years.
On the other hand, $100k is by no means the largest RSU grant you can get, so, basically, we have no damn idea. Overall it’s pretty silly to speculate about someone’s net worth unless they’re excited to talk about it.
But the larger point that high performing senior engineers at megacorps can make way more than people outside the megacorp world imagine is true and surprisingly contoversial on HN.
Also all those calculations are completely forgetting that money is a time-sensitive value. If invested wisely, the first $ from 4 years ago would be 1.7$ today if invested into a typical low cost SP500
Google compensation is also incredibly high. $140k is less total comp than what many new grads get at Google.
Despite my handle, I didn't exactly live like a monk. 2k a luxury high rise and 3k for everything else felt positively princely (though the city has become more expensive since I left).
I remember on Bogleheads people talking about how to reduce the risk of investing in something like an ESPP to avoid an Enron scenario, and the consensus was using options in a private account so that you get a definite payoff.
