CoNetrix interview questions

Easy, quick and friendly up until it was determined I wouldn't be a good fit. Some quick context: I have exchanged occasional emails with the COO since 2016. So I submitted my application and received a relatively quick response from HR. Started with a phone chat with the COO, which was pleasant. Then scheduled an in-person interview, which was relaxed, nice and straightforward. Everyone at the company was a pleasure to speak with. Afterwards I didn't hear back for a week or two. I followed up with the HR contact but received no response. So I emailed the COO and he gave me a call about the status of my candidacy, which I really appreciated. What I thought I knew about the company led me to believe that I would at least get some kind of response instead of me reaching out. Definitely left a bad impression on me.
