Muoro Full Stack Developer interview questions

Had two rounds, first round is dsa and second round for me as a full stack developer was for js, they are sending 3 years experienced guy to evaluate a 10 year experienced guy, asks all the basic questions at the start gives you 2-3 coding problems and after that at the end gives 5-6 minutes to develop a tic tac toe game, not sure how I was suppose to do that, gues they work bugg free, rejected based on the app that I was not able to create in 5minutes although I was able to answes every other problem correctly.
