Design a microwave for children.

"I started with a recruiter screen, and that part was really smooth because the recruiter kept me constantly updated. After that I had what was supposed to be the first real PM round with the hiring manager, and they told me the focus would be product vision and understanding the problem space. The actual prompt was to design a microwave for children, so it was basically a product design interview with a lot of clarifying back-and-forth. I was supposed to have three more PM rounds after that, but I got the decision that I was not moving on. So for me the process ended much earlier than the full loop they had outlined."
