Neybox Digital interview questions

WARNING: This company uses Interview Tasks to get work done for free for their Apps. They are not looking to hire at all, just abusing it. Initial call with Panos and Spyros (the founders) telling you fairy tales about looking to expand their team. After the call you will get a task and 7 days to complete it. It will be some screens of the app which they are looking to update with the new design with your free labor. Be smarter than I was, don't do it. After completing the task I got feedback that it was great and that I should provide personal info for the contract, and a contract draft to look through. Provided all info, told them the draft was fine, basically all set and done, waiting to receive the final contract with my info in it. A day later I get a mail that they won't work with me, that my task suddenly wasn't good anymore and that they found someone better for the role. Guess what, surprise, there was no better person, or no person at all to begin with, they renewed their job posting few days later, there are more screens to be done for free I guess...
