Candidates are asked to complete an extensive assignment, which is a proposal for the company's own product. It's essentially doing product explorations for free, which is unscrupulous. This assignment is at least 12 hours of work, which is asking too much of candidates and exceeds what is needed to see their process and work. My suspicions were confirmed when I worked on designs from my own interview assignment once hired. It really lacks integrity and was a poor way to start at a new company.
