first round was hackerrank which was easy, second round was basically to test your knowledge on java , spring boot, third round was related to ds and system design, the interviewer was very rude, he was not even understanding the logic, asked me to implement blocking queue, wrote the logic but seems to be he was more interested in deploying my logic to production , was asking to write class and proper variable name and wanted bookish answer, asked me system desing for notification system, drawn the basic layout , he was expecting everything to be written as proper SDLC process in 1 hour interview, he was too rude , have never given such a rude interviewer in my carreer, even after giving 3 answers almost 90% answer correctly got rejected
