I can assure you they are absolutely paying in the same ballpark as Facebook, Apple, Amazon, Google, you just don't know how to limit your searches to the tech roles.
Depends on the role. $500k total comp is common on the tech scale of the companies I'm familiar with. While not the $800k+ you might see at some FAANG in specific roles, it absolutely is enough to no longer consider FAANG if you're bothered even one iota by their hiring process.

What do you think the average compensation of those companies are?
I’m well aware of the comp levels at at least three of those companies because they are based in my former home town - Delta, Home Depot and Coke.
They pay their senior devs about the same amount as an intern I mentored got as a return offer (cash + stock).
