You can also "job hop" internally if you want to stay at the same company but want a new experience. The thing about huge companies is that they're huge! You can switch to a team that functions completely differently from the team or org that you were in before.

Exactly and this is why I say there isn't much difference between a resume where they switched jobs every 2 years and a resume where they stayed at Google or Amazon or 10 years, because the Google guy was probably also "switching jobs" every 2 years, just internally.

In my country, it would certainly be odd, so it would raise questions. Would not be a showstopper, though we would definitely carefully consider hiring.
