SAP Automation Test Engineer interview questions

It's was really very good ..I have done two rounds same day. Ist round technical round on selenium,java, manual testing and SQL basics. 2nd managerial round and asked about my project and related questions

The technical rounds went very well, even the managerial round was tricky. However once completing all the rounds the final HR round was not in a way it should be conducted. The HRs don't give feedback and I still don't know on what basis I was rejected. And for the final call the HR called me wrongly and told named somebody else who is selected. This is the most ridiculous HR ever.
