Proceed with caution if you are interviewing for this role. A version has been posted for several years now. I personally did a project for it and know of two other very talented and qualified people who did ones of their own. I suspect the job is being used to get free creative work. And the ask is incredibly detailed for a role of this level. One of the items I designed in my own project seemed very similar to a style that was released about a year later. It's such a shame - great product and seems like it could be a good gig but the hiring practices are very sketchy.
