SAP Intrapreneurship Visual Designer interview questions

I was supposed to go to SAP's office in Potsdam to get interviewed and they informed me to switch to phone interview before my trip. The interviewer is in charge of the Intrapreneurship program and they are looking for designers who can establish the program's brand image and bridge it to the company's image. After some questions about my educational background I got asked to do an assignment in 2 hours which was a banner design. The next day I got the second part of the assignment and needed to refine the 1st design. On top of that I had to design an existing calendar into a more visually appealing version. Again it took 2 hours. I didn't pass the second test though.
