I have 30+ years software dev and almost nothing on github. There are valid reasons why a person who writes lots of code, including on weekends/spare time, would not be on github.
For my personal projects I prefer bitbucket. For professional work, it is proprietary and thus cannot be shared (esp not in an interview!!).
Sure, but if you do have something meaningful on GitHub or where ever, and you share this in your CV, I would expect that the interviewers look at that. Or at least, I would not like to do some stupid coding exercises that are less complex, less authentic, and basically one-dimensional compared to my work on these open source projects.
