The interview was about 1 hour long. It was easy.

The technical round will consist of questions around the work you have done and what you have specified in your CV. The interviews are very professional and more of a discussion in nature than a mundane Q&A session.

The interview just asked me some basic questions. I think most people can handle them. I hope others can pass it. To be relaxed, the interviewers speak slowly. It was very well structured. I was interviewed by a total of 2 people.

Overall, a good experience with SAP.
