Amazon Software Development Engineer -I interview questions

Delivered my resume during a small career fair after completing a simple programming problem. Received an interview offer and met two interviewers for 45 minutes each. Questions about design, debugging, and large-scale problem solving. Included a hard distributed computing problem to see how you think about things. Talked a bit about what it's like to work at the company. Interviewers were friendly. Dress business casual. I received an offer within a week.

I went through 3 rounds of phone interviews and each lasted for about 45 minutes. The content consisted most of data structure and algorithms, basic design and coding problems. And I think it is somehow challenging. After that I went to the onsite interview which included 5 rounds 1:1 interview. Almost all of them are technical questions related to data structures and algorithms.
