It was a "science fair" style expo, where all of the completed hacks were on display with one person from each team demoing--essentially over and over again for hours.
Judges came around to review and score everyone (every team had multiple judges stop by), and a shortlist of hacks made it to the final round where it was more of a traditional pitch-off, with different judges.
