One to three passion projects, doesn't matter what amount of stars. Some practice projects in new technologies. Some contributions to large open source projects. If you tick all three boxes there, in my opinion your GitHub account is awesome. Instead of me having to come up with questions to gauge your competence, we'll instead be talking about what's on your github, making you more at ease, and giving me a better sense of your real world interests and competences. It's a win for both of us.

At my current company I'll probably pay less than half as what you'd make at a "nice" company though, so maybe you won't interview with me anyway.
