My area is tightly coupled to a few OSS projects, so we tend to attract people that are active contributors. I've never been let down in the in-person interview by someone with a strong github resume.

Same thing with GitHub activity grid. I don’t even know what it’s supposed to tell. Even if I’m writing code everyday, that doesn’t mean I’m checking it in, and even if I was, I’m not doing it on a public repo or even on a GitHub hosted repo.

It can be gamed too. I remember a thing a long time ago that would make commits to a repository to give it space invaders in the grid!

Or bootcamp grads.

I look at those but they don’t tell me much as people are often working on a template and have had help, so I can’t disentangle what is someone’s work as easily
