Worst hackathon? My second one, it was a hackathon competition I went to with school. A friend and me entered the js competition. Because of our bus being late, we started almost an hour after everyone else. So everyone else was way more ahead of us which gave us not only a disadvantage but also more stress. At the end we were pretty satisfied with our results but we knew we could've made it waay better in the details if we had an hour extra. Anyway, we came in second... major disappointment.
