Discover Melody interview questions

It was an online interview through a third party video conferencing app. The interview seemed ok at first, but beacme somewhat peculiar. The interviewer couldn't answer several basic questions about their company such as: - "Who is the owner/founder?" - "What is your company's goal?" - "Why is an American music lesson company based in NYC focusing solely on Chinese students in China who speak little to no english?" - "Why do you not require at least some fluency in a second language (for either party, student or teacher) if none of the students can speak English? Do you have a specific method to overcome this difficulty?" Their lack of information was surprising and concerning since they are a self-described start-up company with only a few employees. You'd think they'd have a clearer concept of their company and would know who the very few people in it are, especially their supervisors/directors. Also it became very obvious that there was someone else in the room with the interviewer who was off-screen & didn't want their presence known, but was clearly communicating with the interviewer. Very odd. The interviewer said I was great & she would be sending me an offer with paperwork to fill out by that Friday, but never did. It's been almost 2 weeks and my follow-ups/inquiries have not been answered. Judging from the interview and lack of professional follow through, it could very likely be a scam or front company. Their website and list of teachers on it seems vague and contrived.
