It's one of the data signals for success. An ex-FAANG employee is more likely to succeed than a non ex-FAANG, not only are they most likely smarter than average, they also probably have experience in dealing with more complex systems, and also possibly a more valuable network in terms of poaching their ex coworkers. It's just one of those things in life. :-D
