Never set foot in SV nor in the States, but from half a world away it does seem that that figure (i.e. ~600k) for total yearly comp at a FAANG company, given OP's experience, is in the general ballpark, so to speak.

Closer to ~30% base. The big money comes from stock comp, not salary.

He's at Amazon, so the base salary doesn't exceed 185k (and probably 160k).
