The main challenge was the team cooperation in the beginning, since all of our team members were meeting online via ZOOM, and all are in different timezones, it was very difficult to find a perfect time slot that works for us. However, we quickly adjusted that in two weeks and motivated each other to do our best work. Another main challenge would be the fact that we were working for Amazon, a worldwide well-known company, to generate creative new concepts for Amazon was definitely a difficult task, but with each of our efforts and ideas and came up with the final prototype and are all very proud of it.
