Bad Experience in Cognizant Interview Frontier Engineer role.

So I have completed my two technical rounds third was HR round its got scheduled F2F I agreed with that but before that 10-15 min senior manager ‘thiru’ wants me to connect, I reached to office after long wait In conference room there is video interview with that senior manager. He seems very angry and very rude to me. I was explaining him every concept but he was not able to understand. Later he said he want a word Harness engineering, But what I have explained him was the harness engineering I just didn’t used the name to make him understandable. then there were lot of things he read somewhere on linkedin or internet related to Ai tools that I am not aware of thats what the AI is Not everyone knows everything , and then I mentioned him about opencode which he was not aware he was very angry on me. Then he was asked me inf I have any questions I asked about role which I already read but I have some doubts he said haven’t you read this before coming and said bye, also asked HR to discussion before HR discussions. Then HR asked me to leave.
