Skype interview with technical discussion. More focused on React, Redux, HTm5, CSS3, Restful web services, testing. The interview is a skype discussion of how react and redux works. How the components work and how they can be reusable ?

I got a call from consultancy , shortly a week after a video call interview was scheduled and the interview was based on Web development end-end , state management , CI pipeline , Client side vs server side , seo implementation after that interviewer informed me that I have cleared the interview and was given a home assignment of hacker news clone with SSR. I submitted it in 2 days since it was fairly simple for me even the lighthouse score was above 80%, post which i didnt get any update from the consultancy or from the company , after numerous callback they said I have not qualified the assignment round upon which I asked for a detailed feedback and never got a response back from them.
