Etiquette at the judges' table during live demos: what helps and what undermines a team

Small things a judge does during a live demo — phone use, side conversations, facial reactions — visibly affect a nervous team's performance. What to actually do instead.

Requirements gathering, on stage

A nervous team pitching in front of a judges' table reads every small signal — a judge checking their phone, a side conversation, a confused frown — as feedback on the pitch itself, whether or not that's what the judge meant.

What helps a team perform their best

  • Full attention during the pitch itself — save note-writing for the gaps between sentences, not constant head-down scribbling.
  • A neutral, attentive expression rather than visible reactions mid-pitch, positive or negative — both can throw a nervous presenter off.
  • Asking questions that are genuinely about understanding the project, not testing whether the team can be rattled.

What undermines it

Side conversations between judges during a pitch are the single most common and most damaging habit — it visibly signals disinterest to a team that's already nervous, regardless of how the scoring actually goes.
