SAP Junior Software Engineer interview questions

I applied through the website. Was provided 3 questions on hackerank, then asked for an in-person interview. During the interview process, I was asked to solve algorithms regarding linked-lists, BST and arrays and complexity of the algorithms. The interviewer was a manager and a very quiet developer who nodded at times. Lacked patience in hearing the correct answers. Interrupted me multiple times. Was at times dismissive about what I offered as solutions and about my resume and projects. They didn't care about what I had worked on and what my experiences were. They just wanted to see algorithmic solutions. I heard very good things about the culture at SAP but didn't see that at this interview.
