Perhaps, for example, an E3 at Meta can go to E4 in 2 years, but an E3 isn't making 300K total comp at Meta in California to begin with, nor would they go to 500K after promotion.
If you're a hiring manager then I don't need to explain to you that a 50% increase even with the highest ratings isn't some normal thing that happens.
Maybe you've seen it happen, I believe you. My point is that it's not the norm and you should stop saying it like it is.
Google L4 > L5 (270 -> 360)
Meta E4 > E5 (275 -> 390)
Microsoft SDE II -> Principal SDE (182 -> 308K; I intentionally skipped a level just to show the ridiculousness).
Amazon SDE II -> SDE III (240K -> 330K)
Apple ICT3 -> ITC4 (222K -> 333K)
And these are midlevel to senior and these are from the site you linked. If you do junior to midlevel your numbers, on average, make even less sense.
This friend that I'm giving an example of is real, and I feel like he has the potential to get into FANGMULA with my mentorship and then get promoted within that time frame. It's definitely all real and the post was kind of my own internal speech to get him to come over.
Go look at https://levels.fyi , and look at the jumps in comp between bands. Yes some companies may pay +/- %10 more, but it is what it is. Also the market has gone up, yet again, so even levels is a bit behind.
People thinking what I'm saying is BS is just a bunch of cope. You don't have to be a super genius with the grit of god to get into these companies.
