Teltrium Solutions interview questions

Teams pre-screening with HR rep. She told me the CEO had picked my resume, and set up an interview she told me would be attended by other SWEs and the CEO. No other SWEs were present at the interview, just the CEO. It was also on Teams. The CEO did not seem to take me seriously, told me how he knew the industry was bad now (okay?), and about his son's remote business internship where he made sure to network (okay?). Asked for my definition of a NN, when I gave him a technical leaning definition, he said no, like what it does. When I made a very general statement (as there is so many kinds of NNs) he then gave me his which was frankly wrong, and seemed to imply I should've said what he said. He took no interest in my actual experience, not asking any questions when I told him of my projects. He seemed to want to trip me up, asking what I knew about orbital mechanics. Although I was a computer science major and this seemed irrelevant to my qualifications, I had done research with space physics so I said this. He mostly seemed annoyed I had an answer, and asked no follow up questions.
