Realhub interview questions

The interview consisted of a phone call and then a quick and friendly meeting that didn't involved any technical questions. After that, they said their process requires you to do a full day trial (which already sounded weird, it's usually a few hours or paid otherwise). The trial consisted of a quick "training" through a series of videos that explain how they edit and the style of their videos. Then, it's your turn to make a complete video out of a new project. When it was done, at 5PM, nobody was able and available to talk to me, after I spent all day there and they said they would let me know. No one got back to me and when I asked they said they found someone else. Weird fact is that I found the same ad on every hiring platform published over and over again every month which means they are keeping doing the same thing to every candidate, I assume. I have the impression that this is a clever way to get some job done for free. I would be careful if you're going there for a "trial" and don't expect to be hired.
