I quit last June after 13 mostly consecutive years in tech. I haven't saved enough to be financially independent but I can coast for a while. Even at a company that seemed to have good work life balance, I couldn't take it so I have no idea how you FAANG folks do it. I don't know if I'm just not suited for the career or what, but working as a software engineer caused several stress related health problems that have either gone away or drastically improved over the past year. I can't imagine going back, it's not worth sacrificing my health and happiness.
