Astra Agencies interview questions

I found this job on Indeed. I was initially contacted to book an interview via text, which I found really odd. They also didn't disclose who they were until I asked. When I expressed interest in booking an interview they ceased contact for the rest of the weekend, so I initially thought I had been ghosted. In the meantime, I did some more research on the company and came up with surprisingly little. Their webpage is extremely vague about the work they do, and considering they had exactly one position open, for well over a year, and available in numerous cities across North America, I started to get the feeling that this might be a multi-level marketing kind of deal. This is also reflected in the language used throughout the company website, which promises 'near limitless earning potential.' There is nothing included about the types of companies they represent or collaborate with, nor a comprehensive history of the agency. It set off my alarm bells, and when they finally got back to me on Monday I ultimately decided to decline the interview. Very weird vibes.
