They made a mess. First they said "no thanks" and gave no feedback. After a few days they wrote me back and told me otherwise (after a couple of questions they answered me they made a mistake). As a seconda step of interview they asked me to produce a massive written task about how to change the competitive game. I complied with a noticeable work and waited for an answer. After a month and a half of radio silence I sent an email asking for information. No answer. I waited two more weeks and I asked again. The day after they sent me a brutal auto-mail including the same old bullshits about "careful considerations" and a no as final answer. Meanwhile they published the routine "Balance Dataslate" with most of my ideas in it. Not only they made this unprofessional and disgusting mess but they just stole my intellectual propriety, using my work to their ends. Terrible experience.
