It's rather rare, from what I can tell. Esp. in the context of immigration, h1bdata can be useful. Google llc has precisely 1 software engineer certified at a salary above 300k. 250k, more achievable, with very senior status.
What really happens though is RSU appreciation. GOOG has more than doubled in the past 4 years. You are awarded X dollars of stock on hire and every annual review period, but that is converted into shares awarded every Y months. If you achieved a 1:1 salary:RSU vesting ratio, today that would probably be 1:2, a 50 percent pay raise.
I think the RSUs and bonuses aren’t included in those H1B data reports. Anyone L5 and higher (as well as many L4s) at Google is pulling in at least 300k in total liquid compensation per year.
Just to be clear, that salary is prevailing wage which is usually lower than the actual salary you're getting (does not include RSUs or stock on top of that). In my case the difference was about 30 to 40% lower.
The PERM / H1B figures only show base salary and exclude RSUs which for most big tech companies is the larger factor at senior and above levels. Netflix pay all cash so their PERM figures are much more representative and match the levels.fyi numbers pretty well, giving me confidence that those self reported figures are broadly accurate.
(When comparing keep in mind Netflix hire only at senior software engineer level and above and have a single level title so staff/principal levels are collapsed to senior just with higher salaries.)
This is why a simplifying assumption was made with the 1:1 ratio of salary:RSUs. Obviously it matters when comparing two companies, but in this case the question was simply "who makes 600k" and the answer is 'probably nobody unless the stock did real gud'
The salary:stock ratio increases the higher Your level. 600k would likely be an L7 offer, though you could reach that at a lower level through stock appreciation.
