I had a superday, which to their credit was paid. It was for a technical product role which they wanted to hire people with some baseline technical ability, but it wasn't a coding job. I was up front that while I can code, and do build my own projects, I'm not a app developer. The superday was an app development exercise, and they let me know I didn't pass because my app development skills were not up to snuff. Not really sure how or why that played out that way, but at least I was compensated.
