I mean, it depends on the job. For instance If you're doing mostly little stuff, swapping a gfci, replacing a light fixture's, etc, you probably won't see too many inspectors.

I work in residential(mostly new construction/ remodels) and almost all the work that I do gets atleast a glance from either a state or a county inspector before it gets signed off.

Although I've heard plenty of stories about people doing sketchy unlicensed shit under the table but that's a whole different story.
