Savage Game Studios interview questions

I was given a test that was estimated to take 8-10h work (more than a work day already). It was actually way longer than that. I received a first round of feedback that was all positive. I answered some questions after that feedback, and then I was told they wouldn't follow with the hire. No feedback on why. Quite frustrating after almost 16h of work in this. I was eventually provided feedback once I asked, and basically the feedback focused on me not brushing off the requirements they wrote on the test. So basically I was supposed to push back on what they asked me to do in the test (fyi these changes would drastically change the game balancing, something that is not a job of a UI artist).
