SAP interview questions

Applied through the website and emailed a recruiter directly. A different recruiter contacted me for an initial phone screen that took about 10 or 15 minutes. This call just confirmed my background, my eligibility for the program and my availability. The recruiter informed at the end of the call that me that she would recommend me for a phone interview with a manager. The first phone interview was arranged over email.There was some back-and-forth and confusion (delayed emails, a missed call) relating to this phone interview. But once we connected, it was a pretty friendly chat. A lot of the questions were typical for a sales/business strategy/marketing rotational. The program is relatively new, so the managers do not have a lot of insight into exactly how the process works, but they can still explain the overall culture at SAP and what the company needs. Within a week, I received an email from my original recruiter inviting me to onsite interviews. The interview date and time was changed a couple of times, but it was not too much of an imposition. For the interview, I was led into a small auditorium with about 15 fellow program candidates. We were then led individually conference rooms for 2:1 interviews with conference managers. These interviews were about a half hour to 45 minutes. The first was rather laid back, generally asking questions about my background and my interests and more conversational. I think I lost the job offer in the second interview, which was a bit more pointed. One asked questions about what areas of the graduate academy I was interested in. When I told him, he replied that the area I mentioned does not match my skill set, so apparently I had the wrong impression of the field. He also asked about my undergraduate GPA (I'm a graduate student who earned my BA 9 years ago). I don't think I lost the position because I flubbed the interview per se. I think that I just didn't have the right answers.
