I've looked through GitHub code before, but it's hard to weight it too much since not everyone can even have significant open source code in the first place.
That being said, a particularly impressive project or a history of contribution is a huge plus to me. It's a great way to add some credibility to your claims of technical interest. Everyone says they're in to big data or ML, but actually showing some (even throwaway) work in that area lets me know you are active in your interests.
