I don’t think I’ve ever met full stack people who are equally proficient at both. Even within either of those there are various directions you can go.

Normally when I interview for FS I say I’m strong backend and can do logic work on FE quite happily but I’m not so much a visual person. Never met an interviewer who had a problem with that. If the technical task is something visual then they end up with a solution using MaterialUI or similar, not hand crafted beautiful CSS.
