A design challenge I received from a job interview – “Create a new product idea and define the key UX features that can improve billions of people's lives by enabling them to record and track their dreams.”
Time constraint – “4~5 hours. If you're feeling inspired and want to spend more time, you are welcome to do so, but it is not required or expected. ”
As a dream enthusiast, I have a lot of inspirations, so I spent 2 hours on research, 7 hours on designing and creating the prototype, and 2 hours baking the slide deck and submission. 11 hours in total.
