Total comp for my college hires averages around $150k.
Total comp for my career level ICs averages a smidge over $200k.
My top 10% have total comp in the $350k neighborhood.
The very few folks who are at the staff/principal range (depending on which companies titles you're using) are taking home $500-800k (mostly in stock). If we consider attrition, it's probably only 1 in 150 of the engineers we hire who ever hit this tier or above.
The levels.fyi info seems pretty accurate to me. Their estimate for my personal role is within 2% of my actuals.
