Also some people don't particularly value FAANG tech. Speaking for myself and some of my co-workers advertising algorithms, consumer, enterprise and financial tech just aren't that interesting. Sure the engineering can be impressive, but all that effort for what? So Adsense can be better convince people to buy crap they don't need, Apple can make its products even less practical, Amazon can more efficiently abuse its warehouse staff and make AWS fees more opaque, and facebook can sell your information more effectively while it keeps you up to date with relatives' conspiracy theories? At least Netflix provides entertainment value.

Not saying that's all said companies do, and some people (whom I lovingly refer to as "puzzlers") would enjoy the extra complexity and challenge for its own sake. But I wouldn't say the FAANG companies have any particularly inspiring missions. Not that such missions are easy to find, and they almost never pay as well, but they certainly don't seem to exist at FAANG.
