Hoping this will save others some time. I've wasted my time on this scam twice, so learn from my mistakes. This applies to a lot of industries.
Be wary if your invited to interview for a mid-level management position in an established office. LEAVE immediately if you walk into the building and realized there is only one office space, or worse, a presentation room with chairs lined up like a classroom.
Don't be polite. The interviewer is about to offer you a sales position with no benefits and no guarantee of a living wage. There was never a full-time position available. You just walked into a company with high turnover that needs more warm bodies.
