Whereas in some other, smaller companies there are perhaps one or two ICs at that pay level, they have been at the company for a decade, and hold all the tribal knowledge. No one ever gets hired into that type of position.

No one. I hate ppl here asserting that they landed FAANG like comps without leetcoding.
OpenAI is paying way more than 420K for ICs [1].
