Anorak interview questions

I was contacted directly by the company's product manager for a video conference interview. The interview explains the company's mindset, the products the company has, how it works and how the process steps are. I made an introduction about myself, then the product manager talked a little about the company and asked me a series of technical questions in which he was clearly reading the questions with the expected answers. About 9 questions were asked, of which I answered at least 8 correctly and the feedback was that other candidates were better. Shameful this kind of feedback.
