Questions d'entretien chez ProdataKey

Had a Zoom interview with the CTO. I was told this would be an introductory, intake interview so I didn't prepare for technical questions. He asked me some questions about myself and my experience, then he started asking me technical questions. I bungled the first one, probably just because I wasn't expecting it, but then he asked a couple others that I did well on. Then he had me do a coding challenge live while he watched. I didn't know this was coming, so it caught me a bit off guard. I was nervous and so I didn't do as well as I ordinarily would have. The question was taken from a standard coding challenge website. Throughout the whole interview I got the impression that he wasn't impressed with me. This was confirmed when he cut the interview short during the coding challenge, thanked me for my time, and left the call. In my opinion the coding questions he asked were silly, and don't really reflect my experience or skills. The vibe I got from him is that he was expecting someone with a deep, memorized knowledge of computer science fundamentals. Frankly, such specialized knowledge usually doesn't come up in the daily work of a software dev job. His expectations were unreasonable. If he really wanted to assess whether I can do the job, he should have just asked for a sample of my work and had me explain it to him. Instead he got lazy and just borrowed some generic, useless questions from Leetcode. I'm not impressed.
