Five mistakes every first-time hackathon judge makes (I made most of them too)

Scoring on charisma, comparing teams instead of scoring against the rubric, and other first-time-judge mistakes — and the simple fixes for each.

First-time judges make a predictable set of mistakes, mostly from applying instinct instead of the rubric they were handed.

The five

  • Scoring on charisma: a confident presenter with a thin project outscores a nervous one with a strong build, unless you deliberately correct for it.
  • Comparing teams to each other in the moment instead of scoring each against the rubric independently, which drifts as the day goes on.
  • Letting the first team anchor the scale — team one gets a 9, and every later team gets judged relative to them instead of the criteria.
  • Asking softball questions instead of the one question that tests whether the team actually understands their own project.
  • Writing no notes, then trying to reconstruct feedback from memory at the end of a long day of pitches.

The fix for all five

Score immediately after each pitch, against the written rubric, with one sentence of notes — before the next team starts. It sounds small; it's the single habit that prevents most of this.
