CG Infinity Test Automation Engineer interview questions

I got a call from HR. They called and next day I went to attend it. First round was with HR. Quite weird interview. She was overreacting alot. Then I had another round of HR I suppose where the interviewer explained me the profile. I don't know what was the purpose of two interaction rounds simultaneously by two HRs Then finally technical round was there. It was good. But when I was writing the logics and all, they were whispering. That was disturbing. Also they were discussing the feedback also in front of me. How unprofessional was that. Then finally the managerial round. It was quite professional. Then I was asked to wait. After waiting for half an hour, I was asked to leave. I don't know what kind of interview process was that. IF my technical round was not cleared, why did they take my managerial round. HR didn't even cared to share the feedback on her own. I had to call her for taking the feedback. Literally unprofessional. Wasted my entire day!!
