Well paying jobs typically don't look for people with experience in specific technologies, rather they look for people with experience in relevant domains. And the domain experience you learn at FAANG is worth a ton, lots of companies wants to be more like FAANG.

Example: You are making a search engine, you use technology X. Would you rather hire a person who worked on Google search but didn't work with technology X, or would you want an expert on technology X?

In my recent interviewing cycle I got dinged in most interviews for not being a React expert. Every panel knew going in that my React experience was recent and limited. I have 4+ years of relevant domain experience at a FAANG on my resume. I laughed with interviewers about how every few years the de facto tech stack changes and every team I've ever joined required me to learn completely new (to me) frameworks. Still got dinged.

I wish what you're saying was the truth but I think it's very much the minority.

HTTP requests work exactly the same on the other side. If anything some ex-faang have an edge as they generally see many trends years before they permeate the wider industry
