During iGEM's Den, each iGEM team had 20 min to present their team’s project. After their pitch, the judges would give live feedback on the team’s presentation, whether it just has to do with the presentation itself or details of the project. Judges also filled out an evaluation form with helpful feedback for each team to help them improve their pitch for the Grand Jamboree. The judges were either professors specialized in the topics of the presenting iGEM team, or they were previous iGEM members that, with their experience, could help them by providing beneficial guidance to the presenting iGEM teams. It was very interesting to hear other teams’ projects and see all the different approaches they are taking. It was also very beneficial to receive advice from experts in the fields we are working in, in order to be more prepared for the Grand Jamboree. The event was also live streamed on twitch, giving an opportunity for other teams to watch the event and learn from the judge’s feedback as well. The link to the recording can be found under figure 4.
