What to collect at the end of a hackathon so judging is quick and nobody's demo gets lost.
01One submission per team
Collect everything in a single submission: a repository or demo link, a short description and, optionally, a deck or a video. Judges then open one place per team.
02Limit the description
150 words is enough to say what was built and for whom - and keeps descriptions comparable at 2 a.m.
03Let teams resubmit until the end
Teams will push fixes up to the last minute. Allow resubmission until the deadline and judge the latest version; earlier ones stay on record.
04Close on time, every time
Announce the exact deadline with its timezone, and let the system close it. Consistency matters more to participants than a few extra minutes.
