SAP Software Engineer interview questions

I had 2 technical 1:1. They mainly focused on analytical & data structure skills. I did well and all i got positive response. But HR is very unprofessional. He had never updated me anything regarding the progress. No Proper mail communication from HR even after i completed all the rounds of interview. Whenever i call & ask regarding the status , he replied it will take one more day. Then again i called him after a week. His reply was "Sorry you have not cleared the interview". HR Result it seems. Then he was not the HR of SAP for the past 1week whenever i ask the status? . why cant he just send an update? It's a worst experience with these kind of HR.

About 80% cleared this phase. 4th round Managerial HR- The main question here if you would like to a manager someday or not. I yes, Some hard Case Studies are asked on a 1:1 interview.
