Is 4G Antenna Shop Inc a shady company?

Does anyone have experience with this company? I have an interview tomorrow for an Administrative Assistant position with 4G Antenna Shop.

While there are definitely reviews on the Better Business Bureau, the actual location of my interview is in a very unusual place. It's inside a pregnancy center and across the hall from there. Not to mention the business doesn't seem to have a "set" remote location from a Google search. I can barely find any history on the company itself, and Indeed.com has zero reviews.
