Interview with Infosys

I have attended interview with Infosys. I prepared well for the role of python developer. But my experience is very worst. The interviewer didn't asked self introduction. From that time, i noticed something weird was going. He repeatedly made Woww sound during interview session. I concluded how toxic that person is. He raised questions from my current experience stack instead of requirements. Interview went beyond scheduled duration. He used me well and formally rejected me. How unprofessional those panelists are.. My mistake is once the interviewer deviated from relevant stack questions i was not disconnecting my session
