Horizon Innovations Account Manager interview questions

Intial contact was a phone call that I was unable to answer at the time. They left an voice mail and sent an email immediately, and I appreciated their thoroughness. The I spoke with on the phone was very personable, friendly and professional. What I found odd was the vague information online and at the interview was I only saw/heard two people in the office, despite being there for some time. It's highly likely there's nothing wrong, but something didn't sit with me right. It probably justs boils down to it not being a good fit for me.
