First it got nothing to with that i am not accepting my rejection anyway i would not work with such people and culture. I would not bother to write but since i believe i nailed the interview given all correct answers moreover gave my 45 minutes I would guess that I were rejected not because of My answers, but because cultural fit .I do not come across well in what they have and I suspect that if I came across the same way in interview, that the person decided that they could not work with me. You don't give feedback to HR about your opinion of the interviewer. because they believe that interviewer is working with them form six years even. though person is no good and does not know their stuff does not even introduce well them self as company and individual yet they are working for a company i find it strange. they should have been got rid of well before they were allowed to start interviewing. If there had been any complaints they should not have been allowed to continue with interviewing external candidates. or should do keep watch on interview. Recording interview call without consent is breaching of privacy but not if it is mutually agreed and taken consent from both side.so do not talk about laws dear you are just nobody altum labs not alphabet inc(google). I Contacted HR and wanted to share my feedback but HR is not even interested in listening. they believe only HR and interviewers got the right to questions but not the candidate. And you ask questions to them they are like as senior person in industry you should have done your research about company but as we all know that lot of time those companies shows fake details, reviews and things on internet. My recommendation would be move on with another opportunity Your career will not thank you for it. your time is not worthy for such interviewer.
