I'm also in the Seattle area, with just-over 10 years' full-time experience and started my career at a FAANG and everyone in my orbit (with similar education, roles and experience) is around 150-180, I don't personally know anyone who has admitted TC over $200k.
I'm not skeptical of your claim, but just sharing my experience.
(Yes, Levels.fyi makes me feel insecure about my career accomplishments, but at the same time I don't interview well...)
I came from larger companies (including a FAANG), and compensation there (salary, bonus, and RSUs) ranged from 1.5-3x my current compensation. Most of the people on my teams were in the $250k-300k range, with a few others at least doubling that. Some amount of that was driven by stock appreciation in a bull market.
The money's definitely out there, especially at higher levels in public companies.
Right, I'm not denying that - it's just that Levels.fyi puts numbers that high at 90% percentile TC, the industry median is still significantly lower.
