Greensky Games C#/Unity Developer interview questions

Applied online via Indeed some months ago. Didn't hear back. Applied again via their own system. Heard back within a week or two inviting me to an introductory meeting. While waiting for that one, heard back from my initial application, saying it was not a good fit (which was clearly some botched review as it was the exact same resume for the exact same position). Had the introductory interview regardless (they seemed to have no awareness of my previous application), where I thought everything went really well. I have the skills and experience they want. A week later they email me to say they won't be moving forward, and they can't give me feedback due to legal reasons, but I should welcome to apply again (!?). I see today they are still advertising the same positions, unfilled for months now. These people either have no understanding of how to conduct a proper hiring process, how to write job descriptions and how to screen people, or they are up to some monkey business wasting everyone's time.
