An ordinary mid-level engineer (3-4 years of experience) would expect to make $150k salary with 10% bonus and about $120k equity. If you add that all up your tax return for the year will show approximately 150 + (150*0.1) + (120/4) = 195k taxable income.
As a rule of thumb I would say:
New Grad: $140k total comp
Mid level: $200k total comp
Senior level: $250k total comp and up
Numbers can go far above that for FAANGs, especially Facebook and Google.
I can’t speak to the rest of the numbers, but given the numbers for the bay area are so far off, I would not put much stock in this analysis.
