For all FANG / MANGA folks regarding WLB

How do you manage working at a FAANG company longer than a year? How do you deal with a stressful lifestyle without personal time? Especially when there are meetings overseas or on-call. Sometimes I feel like life is passing me by. Don't get me wrong, I like to learn in my free time or read something IT related but how sustainable is this lifestyle? How do you know you are in burnout and how do you cope? Are you giving up on the role? Just curious...
