Screening call with recruiter where I was asked to walk through one of my case studies. Then zoom interview with a design manager where we talked more about my experience and interests in design. After that interview, I was then given the option to complete a take home challenge or present one of my case studies during a panel interview. I chose to complete the design challenge and had several days to complete although the instructions said they didn't intend for you to spend more than 4 hours but feel free to spend as much time as you wanted. For the panel interview I presented the design challenge to a staff product designer and senior product designer. They had not received my solution or materials in advance even though I had submitted to the recruiter as instructed which was a little frustrating. This was followed immediately by an interview with a product manager.
