I don't think so.

I host all my personal projects on either GitHub or GitLab (depending on build pipelines).

The majority of my personal projects are private. I get zero benefit from the "social" coding aspects of either platform.

I use remote git repos to both backup my code and have access to it when needed. For example, I have a fairly large personal project with a complex React frontend. I often pull this up to jog my memory at work when I hit similar challenges at work.

For junior role, it might be helpful to have a Git* presence with clear commit messages/branch history (at a minimum, it shows your ability to use git).
