Looking at Walmart pay reports: https://www.levels.fyi/companies/walmart/salaries/software-e...
I see many engineers with 10+ years of experience earning ~$200k in the Bay. No disrespect for your friends, but if you're a talented engineer at this level of experience, you can do a lot better than working for $200k in silicon valley.
There are many other companies that will substantially beat this kind of pay. If you failed to get an offer at all of them, the problem is probably not "inconsistent hiring practices."
