Conflicts of interest in hackathon judging: what to do when you know a team

A judge who mentored a team, taught them, or knows them personally has a real conflict. How I've seen it handled well, and what organisers should ask upfront.

A judge who mentored one of the competing teams, taught several of its members, or knows the team socially has a real conflict of interest — even if they're confident they can score fairly.

How to handle it

  • Disclose the connection to organisers before judging begins, not after a result is questioned.
  • Recuse from scoring that specific team; let the rest of the panel cover it, or bring in an additional judge for that slot.
  • If recusal isn't possible (a small panel, a small event), disclose to the other judges so they can weight your score for that team accordingly.

Organisers should ask this upfront

Include a simple conflict-of-interest question in the judge briefing form: 'do you know any competing team members personally or professionally?' It takes one line and prevents a much harder conversation later.
