Vitalief interview questions

The interview was normal, except for near the end of it, when the interviewer requested that I create a PowerPoint off of their “Ambassador Program” document, since “(executive I’d be supporting) was going to ask that I create a PowerPoint anyway” as a qualifier. That’s fine, I’m quite advanced with PowerPoint. After submitting this PowerPoint it took over a week to hear back. I had to follow up to get a response. The response I finally received was that the executive “at this point has decided to move in a different direction with this position.” Nothing else was mentioned. So, I’m quite sure I did free work for them under the guise of being hired. Oh, and the executive I would have been supporting is nowhere on LinkedIn, which I found odd.
