Interviewer was so monotone I thought my audio broke

I had an interview today and the interviewer spoke in the flattest voice I have ever heard in my life. I genuinely thought my audio cut out because there was zero change in pitch the entire time. I’d answer a question and he would just stare for a solid three seconds blink once and then read the next question. No nodding, no little okay nothing. At one point I even checked my tabs to make sure the call didn’t freeze because the vibe was identical + even during the call InterviewCoder had problems picking up his voice and the question so I think that says enough. Somehow made it to the end but I’m still not convinced that man wasn’t buffering the entire time.
