I did an internal transfer and took over from a team that I think had been in this state for some time— it was really the ideal scenario because in many ways I wasn't having to ramp on everything the way a true new hire would, but I still had the clean slate and clean calendar to immediately get a bunch of stale systems upgraded, processes cleaned up, start into writing some documentation, research new tools to deploy, etc. Very invigorating and a lot of progress possible in a short period of time.
