Accenture Automation Test Engineer interview questions

1 st round: MCQ -> question from java, selenium 2 nd round: Online interview. In dept questions again from java selenium 3 rd round: HR connect and salary negotiation. Offer discussion

I got call from accenture regarding job opening. Firstly a test neend to be cleared for interview process, which i have given and also cleared. I got the call from HR for interview round. First time the day for which interview was scheduled, it got cancelled in same day. Then again interview got schedule for some other day. I have given the interview. It was all well. Interviewer asked around 20 questions around selenium, testng, java xpath etc. I have given answers to almost all questions. He was even satisfied with my answer and wrap up the interview in 30 mins earlier. Interview went great still they rejected me just after the interview on mail without any feedback. I have connected with HR to ask for feedback and she has given me the feedback. The feedback has some points that the interviewer not even asked me, and has given all negative points for the answers that i have given correct answers. All false points in feedback. Don't know why this happened and HR said she can't do anything. Waste of efforts and time.
