Upside interview questions

Phone screen with hiring manager was easy with some behavioral questions. Next round was a take home case assignment to be presented to a Group PM - timeline was roughly a week. This assignment was free work for Upside, as it was directly tied to their business ("Upside wants to expand into a new vertical. Which vertical should we expand into and why") and required market research, a new product strategy, low fi mockups, and a testing plan. The interview itself reflected poorly on the company culture - the interviewer arrived late and was very transactional in his manner, not making an effort to connect on a human level, just wrote down my ideas. In the end he made no acknowledgement of the significant amount of work required for the assignment or to thank me for my time. If Upside continues to ask candidates for a product strategy related to their business, they should compensate candidates for their work. The interview process ended with a seemingly automated "No-Reply" rejection email. Overall a poor and impersonal interview experience.
