I had three rounds of interview first was a screening call with HR and it went lovely, on second round it was a live coding session and questions were too easy for senior level. On the last round I had I have interviewed with the engineering manager who had his background on front end development and was not qualified to evaluate a backend developer. He had a weird obsession on using specific framework for tasks. He was not looking a good engineer but engineer uses the exactly the same frameworks they're using.
