Recently went through the leetcode circus myself and ended up with an offer in this range, thus 4-5x my previous salary, and I have 7 years of experience. The interview had almost nothing to do with my work experience (which isn't that great btw) except for the behavioral portion. I am not exceptional either - most HN comments go over my head really quickly. Now I can actually think about affording real estate and starting a family.

Companies that can pay this much aren't rare. They're all in plain sight. FAANG, Coinbase, Stripe, Brex, to name a few.
