This overall makes sense.

In my experience at a FAANG working on one of the core services for both internal and external customers, essentially two kind of people crank out great code:

1. "rock stars": they joined the company at 25 and they're still there at 35+. they're allowed pretty much everything (eg: no RTO, work from home country) and they know many codebases across the services very deep. they aren't really motivated to go look elsewhere, their grass is already one of the greenest.

2. people with kids. the company pays enough. they aren't really interested in switching job, rather they want to provide for their family. they're good, and maybe every now and then will push through for a promo in order to face new challenges in life (another child coming or some kind of new financial burden).

i'm not saying either one is inherently good or bad.

but yeah. in such large companies you end up working in on a very large codebase that interacts with other very large codebases. all the codebases are proprietary and you're lucky if you can use some libraries that come from the outside world (that have not been heavily lobo^H^H^H^H customized - the libraries i mean).

you do what you can, you do your best, but you're essentially a relative beginner.
