Coveo Solutions Security Analyst interview questions

I applied online and after a week I had a phone screen interview then I had a video call interview with 2 guys who are a product manager and a programmer. They asked me just about developers. They didn't know anything about security issues and even when I asked them about which security tools and siem you use? They didn't know and answered to me ,we use many things! It was ridiculous and boring. The day after I got an email that you're not eligible for that position. I'm wonder how these guys recognized when they were not eligible to interview in my field.
