If I'm investing the time to look at her/his github, I have probably already invited the candidate over for an interview, or am seriously considering doing so.

If I'm investing the time to look at her/his github, I have probably already invited the candidate over for an interview, or am seriously considering doing so. I'm looking for anything that gives me an insight into the way the candidate approaches problems, than I can then use to further the interview. Any github that contains more than just course work is fine for that.
