Not the technical work so much as juggling the methodologies and debating them, because companies claim to be Agile but almost always use some customized version of it. I've seen many new coworkers with Agile, Lean, and/or Scrum experience or have gotten certifications come on board and are instantly befuddled by the bastardized processes being used in the new company. It's happened to me, also.

Do you guys feel that way, too? It kind of makes me miss the old days when you just came to work and got your stuff done without any debates about how scrum meetings should be run, debates about whether or not (or how much) requirements documentation is needed, debates about whether we're using Lean or Agile or Scrum or Waterfall, whether we're doing it right or not, etc. etc.

And then every new job, you repeat because it's all different in new, strange ways.
