And lots of bad stuff: the communication burden of wrangling huge numbers of people, bad decisions by leadership that you're helpless to impact, just the general difficulty of having one's values align perfectly with those of a big shareholder controlled faceless blob, figuring out what to work on that will be both satisfying and aligned with the right peoples' goals (that is, fun coding projects are often not impactful while thankless slogs are, at least for more senior folks), etc.; essentially, the politics are harder to navigate and feel satisfied with.
To highlight my first two positive points: the stability and compensation has allowed me to pay down all our debt, buy a house (recently refinanced to a 15 year mortgage), save up a year of expenses, allow my wife to go back to school, and pay for a couple kids to be in a lovely daycare. Most of that would have been much more difficult in my previous life in the startup world.
I'm very happy I got the job (when I was about your age), but I also think often about leaving it.
Hope that helps!
The compensation is also something that is not as clear to someone who had a career arc like me. I've always been able to make money to take care of myself and immediate family, but making consistent FAANG money changes the way you plan and help people. I've been able to help one family member go to school, another go to med school, multiple members to move closer, allowed my parents to retire early so they didn't have to work customer facing jobs during the pandemic, donated tens of thousands of dollars to local organizations, etc
If I was single I might've left and worked at startups or smaller companies, but I wouldn't now that I see how much impact I can have on those around me by just going to work and working hard.
