There are many steps so you can’t show them all (each step has sub steps and so on). You prioritize steps, but when you are showing your work you focus on steps that are key for you and think would be key for your interviewer. It isn’t crazy that you would guess wrong about the latter given you don’t really know them.

A reasonable candidate can definitely make the mistake of not showing steps that they think aren’t important (and they can also go the other way and show way too many unimportant steps).
