I literally have PDF copies of offers I received in 2018 from both Facebook and Google for L5 roles in the $400k range, and things just went significantly crazier since then. And I am the most average engineer you can imagine, with most of my peers in a similar situation.
I cannot comprehend how your TC can just be $250k at Google after 5 years of refreshers. That’s like L3 comp in the pocket of the organization I’m at.
however, in practice, few are able to land such positions when interviewed externally - I’d believe the pass rate for L6 is less than 1 in 10. Even after accounting for screening steps.
