Fynd Fullstack JavaScript Developer interview questions

4 rounds - 3 Technical + 1 round with cto Technical rounds basically had javascript concepts, share screen and code a problem, system design questions. CTO round was mostly why you are interested to join or why this location. The technical interviews went well, but they didn't even give a reason for rejection or feedback, even when one interviewer said they had written it. Kinda disappointing to reject over 5 min of CTO discussion.
