I checked Blind and total compensation info is pretty much in the right ballpark (for my company and my partner's company). This must be a nightmare for HR, who wants to hide that data as much as possible.
In a real case I had a recruiter tell me they were "getting me" $60k a year in options, which in reality has been more like $10k. I like https://tldroptions.io/ to reality check the equity portions.
It's certainly true though that you can't get the kinds of top compensation numbers you see on Blind if you aren't good enough at Leetcode questions (and systems design questions) to get offers from multiple top companies.
