Broctagon Fintech Group Java Lead Engineer interview questions

There were 3 rounds. 1st one was coding and other two were F2F Technical round. Coding round was hosted on Do Select Platform. 2nd round was with lead and he asked me about some Java & Spring questions. In the 3rd round, the interviewer asked me some 1-2 basic questions and about my project also he explained about their projects. Then he told me that he need to call his tech head as he was just a fill-in as his tech head was busy. After that HR comes and says that, they are confused and will update me on monday. Wish they had handled the interview process more professionally and wouldn't had wasted my time. Its seem the interview was just for name sake or there was a huge communication gap amoung thme self.
