Daedalus (Germany) interview questions

It consists of 3 rounds in total, I passed the first round which was simple HR round with basic structured questions about the company, job description, salary expectations and notice period. Second round was a Technical one, It was pair programming and I performed all the tasks which was given, It was more about the React so I have expertise on React so performed really well. Like, props drilling, state management, redux vs context vs state. But later on I received the rejection without any reason. That was totally Dumb. They should give any feedback. I was really not expecting this rejection because of the interview experience. Even the interviewer said by himself these answered are totally right.
