My own experience as tech recruiter, who looks at dozens of resumes a day, is that I only take some minutes to review your publicly available code. If I see commented code, rough violation of coding standards etc., that is bad and I will ask about it. So if you share side projects, remember that it gives the interviewer "attack surface" to disqualify you. However, good interviewers won't look 20% for your weaknesses…
Be careful, the coding in free time is an interesting signal to be sure, but considering one engineer to be better than another purely on the basis that they code in their free time is anti-diverse
Obviously, if I really take this as a main parameter, I will be hiring probably 22 yr old kids with no relationships. I only see an indirect relationship to diversity. Still, good hint to keep that in mind.
