Coding, programming developer role good hiring in five round with technical three it took approx 2 months in break to complete the process each round was having panel of 4 to 5 person

I got a call from HR, I gave only one round of interview and was rejected. Interview was very great but the interviewer may not wanted to hire me. Those were all childish questions, all definitions in JavaScript, react, redux, css. I answered them, all of them, out of 1.5 hrs of discussion the hr has to give me feedback on thr 5 mins which i answered confusingly.. This was not my first interview, i gave hundreads of interviews till date and i know how it works. It was clear that the interviewer did not want to hire me, so he wantedly gave the negative feedback. I hoped for good, but after the feedback, i was like what a waste lf time.. Hr was very polite untill the interview happened, but after he got the feedback he changed his tone.. What rubbish.. The ciena interview process has to be more mature as the company is very grown up.. I could have argued on the feedback but looking at the tone of hr I thought this seems not to be a good place to work with such people and such politics.
