Clean Air Systems interview questions

I applied online in response to a pop up; I think I supplied only name, email address & telephone number - not really very much; probably not my highly informative LinkedIn profile... What seemed like a few weeks later (maybe it was only a few days), I got a telephone call from a young woman saying they had looked at my application and wanted to schedule an interview. Unfortunately she was not very forthcoming with answers to my questions about what the job was about, and I could not get a telephone number in case I had to cancel the hastily scheduled interview. She did answer that I would be interviewing with two persons, and though I probed carefully, she actually misspelled the name of the person who was not present for my interview. When I pressed for a telephone number she carefully repeated the exact same words indicating everything I needed would be in the email I would receive. When I happened to look over into my InBox, I saw that the email had indeed arrived while I was still on the phone with her, but there was no telephone number. I figured she was a short-termed employee under intense pressure to follow a script. I was trapped, I either had to put on my suit or be a no show. Luckily, I had a clean shirt, and no schedule conflict! She had told me to bring a resume, so I tweaked on that hit the highpoints of my exemplary customer service track record. I enjoyed meeting the young woman who had called; that ring on her left hand sure seems to have a lot of caratweight; maybe she's married to one of the principals of the organization! She gave me a clipboard and told me to fill out both sides. The young man who interviewed me had lightly examined my resume, and told me right away that he figured I might have heard before that I was highly overqualified for the job. I have used this company's product(s) for decades, and have a good respect for those products. I enjoyed talking with the interviewer, and would love to get to have a chance over coffee or lunch to get to know a whole lot more about him. He had to halt our interview to meet his commitment to others who had been summoned to a kind of audition. He had the young woman provide me with some kind of order form that included the company telephone number. If I actually had time, I might want to volunteer an hour and a half to sit through their training demo... Maybe I'll find some time next month, and give them a call. I will mark the question "Did you get an offer?" as "No" though there is still an outside possibility that I might get one.
