BKA Financial interview questions

I was contacted by this employer for an interview, but I never actually applied for the job. I went to the interview anyway , which took about an hour, but left feeling very confused about what the job itself actually entailed yet at the same time very intrigued for the same reason. The entire interview was very vague; vague details about the position, vague answers to any questions that I asked and vague questions asked by them making it hard to know if I sufficiently answered what they wanted to know about me. In the end they did not reply to email I had sent to follow up nor did I hear from them within two weeks time like they told me I would.
