Amazon Software Development Engineer interview questions

It was an online programming and agility check interview. The first 30 mins were for programming questions and the remaining 30 minutes were the problem-solving questions. There were about 5 programming question, 2 were easy, 2 were difficult and 1 was average. The problem-solving questions were of logical nature like filling in the missing patterns.

An introductory phone call, Online Assesment and Technical Phone Interview. The first two were good. The interviewer in the third was drowsy and kept on asking the same question again and again about my algorithm. I explained as many times as possible but he said he doesn't get it. At some points, I couldn't hear him. So I politely told him that but he never asked me if I can hear. He just continued with his scripted dialogues. Wasn't asked any behavioral questions or the complexities of my solutions at all.
