Vague, no specific role per say in the process or what type of things you would be working on and the skills they were looking for. The website is from the stone age and the materials to upload are a bit insane and out of date. For example, you need to use their survey so they get to know who you are, use their CV template, upload 3 game ideas and a game build. Seems to me they are looking for juniors rather than mid-senior designers. This makes it incredibly difficult to complete the process based on the site navigation difficulty and the amount of materials to provide. LEARN TO EVOLVE TO MODERN TIMES!
anyways, I sent AI work materials because the process was just too bizarre. They probably would be taking your ideas if they are good and using it for their own without your knowledge. Don't sell them any of your own creative ideas.
