SAP Working Student interview questions

I was asked for 10 minutes of preparation time to organize an event. There are also some behavioral questions. One of them also asked detailed questions about an experience in my resume

The interviewer seemed to be confused at the beginning of the interview and did not know what questions to ask. The questions did not go beyond "tell me about yourself" even though it was a technical position, no specific questions regarding the job and skills were asked. It felt as if they did the interview because they had to. And they took one month to send the rejection email.
