The HR was fairly quick in scheduling interviews. I had an initial screening round with HR, then an other with the hiring manager. After that, I was given a take home assignment which I presented to a panel and I was told that I have been moved to the final round which included 3 more rounds of interviews. I was getting ready for the last of those 3 interviews i.e. 30 minutes before the interview, when I received email from HR that I am not being considered anymore. They didn't inform the interviewer and he called me for the interview. It was awkward and honestly unprofessional on HR's part. I later asked for a feedback on the interview because after going through so many rounds, I wanted to know what could I have done better, but no one responded!
