There were 4 rounds 1. Online assessment 2. TECHNICAL INTERVIEW - 1 3. technical interview -2 4. HM round So online assessment was of Tree and another was of graph and then next round was technical interview so they ask to solve 2 DSA problems one of heap and another I forget and next round they ask one DSA linked list and sql query and then last Round HM, as I have background of Java and springBoot so asked me about that only in indepth and sql also and the one LLD problem everything went well i got good feedbacks from my tech interview 1 & 2 and HM refuse to give feedback but my HM round was also good enough to get selected i answered almost every questions and then next day i received mail that I am not selected then I asked HR that what didn't well she was also not ready to answer and give feedback.So Don't know what went unwell but this whole process took 2 weeks. Let me know if anyone knows possible reasons or had same experience

Interview was easy, got two dsa question on first was not able to solve completely hence got rejected, Interviewer was really friendly, and was helping me in every process, that was the best interviewer that i have faced till now
