Socialpoint UI/User Experience Designer interview questions

I was very thrilled when Ana contacted me. I liked that the company suggested having a Skype interview before giving a test. It was a pleasure to talk with their Game Designer as I had a feeling that I was talking to a professional, who has a passion for what he is doing. Since the Skype talk was OK I was given a test. The test was rather huge. Usually, it is normal for tests to require 4-8 hours to complete. This one was bigger. You had to create a des.doc with a benchmark from top 3 competitors and their UI/UX insights (3+1 slides), flow proposal, UI style proposal. I spent several days doing it and even had to ask for more time cause the only time when I could do it was evenings and a weekend. I even recreated the style of their presentations to fit. So, after the doc was completed, I've sent it and never get the answer. After two months of pushing, I received an answer from HR that the team had to give me an answer (what?). They had to say that even the test was ok, they were looking for someone more experienced. I asked for more details what was wrong with the test, as it is very important for me but nobody contacted me ever since.
