I've worked on teams with 6 month ramp up times. Almost always this happens because there is an absurd amount of domain/business knowledge encoded in some massive 500k line code base. Tenured engineers gate keep with domain knowledge. The real learning happens by switching between working on those types of systems and then moving to greenfield to implement the patterns you observed.

How do you know if you did a good job if you leave after a few months? Did you leave a beautiful work of art, a bug-ridden unmaintainable mess for others to clean up, or anything in-between?

A large part of experience is doing things that seemed like good and reasonable idea at the time, and then discovering that it actually wasn't. And how do you know what are and aren't good ideas? By sticking around and seeing what does and doesn't work.
