Tecton, Inc interview questions

I heard from a recruiting coordinator on LinkedIn and had a nice chat with the hiring manager. I reached out but heard nothing back for over a week. I received a form email to schedule an interview with the hiring manager. I finally got a personalized email but it was asking me to reschedule because they had the hiring manager's availability wrong. The hiring manager seemed put out by several of my questions. I accepted a role elsewhere. It was a terrible candidate experience.

Interviewer didn't turn camera on for a Zoom interview and the interview lasted a whole 15 minutes (most of the time I was the one asking the questions). The interviewer was so unenthusiastic and I got the feeling he wanted the interview to end so he could go about his day. Has to be the WORST interview I've had in my entire life. Made me come out not wanting to work for the company.
