I have a graveyard full of such personal projects.

In another hand, if you are still maintaining this project, it can be interesting to refactor it and show your process doing it. It can be a great way to show actual useful skills for a future interview or, at least, train to do so before actually using it in a real production project.

Refactoring to a state of the art state while the project is still under development and shipped can be a valuable skill to train and show.
