SAP Software Engineer (internship) interview questions

The interview process was pretty straightforward and had 3 rounds. After a brief 40 minutes technical & past work phone interview, i was called for a face to face interview. Both the interviews were technical with a few behaviorial type questions like what you want to become in next years, why that didn't work out etc. After phone and face to face, it was time for coding test in which i was asked to design and build a Web based system. It had some specific requirements and constraints. All in all they were interested in understanding how much of a 'system-design' mindset I have.
