> It's hard to believe a job on the same company can be fulfilling for 20+ years.

I don't see why not. I have never worked for small companies (always 25k+ sizes ) so my view may be skewed but the scope of these companies are so large that changing a project can mean totally different ways of working and sometimes totally different industries. Can it be that it's easier in europe to change your job context within the company and not so in america?

> Changing jobs is part of professional growth IMO.

Actually it's hard for me to understand why this is taken for granted in America and my home country India. Sounds like KPI chasing to me.
