SAP User Assistance Developer interview questions

The process was unethical, and the behavior of the female managers and HR personnel was irresponsible. After undergoing six rounds of interviews, including two written tests (one online and one offline face-to-face) and four technical rounds, I was informed that I had cleared the selection process. However, I never received the offer letter. A month later, the HR representative contacted me to say that someone else was hired for the role and told you were good in the interview so other team wants to interview you. As insisted by the HR I attend interviews again for a different team in SAP where they took all the rounds again and rejected me without giving any feedback.

This is their title for a technical writer. I was approached by a recruiter on linkedin who encouraged me to apply. I did and was told that they were looking to hiring quickly for this role and that they skipped the initial first phone call. Then I was told my interview was to be cancelled since they were going to hire an intern to fill the position. Then I was told that the intern took another position with the company and they wanted to interview me again. I thought it was unprofessional but figured these things happen. I did the interview, which was with a panel of 4 or 5 other people, it seemed to go well and was given a long and time consuming skills assessment. After that I followed up but never heard anything from them again.
