Amazon Senior Software Engineer interview questions

First telephonic interview which was of 1 hour included behavioural questions, technical questions in the first half. Second half was a system design question. I was shocked to see a system design question in my first Amazon interview but the interviewer walked me through and was responsive

Unrealistic questions and expectations. Haven't used 75% of data structures or algorithms since leaving Uni. All they want is robots, human side is no existant. Glad I didn't get it.
