Knowunity interview questions

I applied and had an interview with a recruiter and one of the founders. After it, I shared my pet project with them instead of completing a challenge. When I was sharing it, I mentioned that it was a bit outdated and I would do things differently now, and in general, I was more than happy to talk about it in a separate call. After this story, I was ignored 😅. A week later, I received an automated response that they had found a better candidate (but that's not true because they're still looking). I still decided to ask for feedback to understand what exactly they didn't like... But no. The answer was silence 😊. Such childish behavior. btw, during the so-called tech interview, there were maybe 5-10% questions about tech.
