I always distinguish engineer vs developer in front end dev by asking if you understand how the frontend works (dom, js, css, etc) vs being able to build frontends using an existing framework.

For example, I once interviewed a FE person with 8 years of exp and he was convinced that only react vdom allows to update partial trees and that previously you had to rebuild and rerender the whole dom. He obviously did not understand how things work correctly.
