Amazon Software Development Engineer interview questions

I had two rounds of 45min-phone interviews from amazon. They are all technical interviews, only the first one involves 1 question about my project that is not that technical. Other than that, all coding questions! Depending on your coding speed, he/she will ask you about 2-3 questions. he/she usually starts by asking you to write an algorithm and then asks for runtime/space complexity, then asks if you can do better. You might expect to read all your code to the interviewer, or he/she might send you a link to online notepad so that he/she can see you typing. Overall the experience is pretty good.

2 round phone + onsite. Questions asked were (1) Desiging deck of cards (2) Algorithms for card shuffling (3) String reversal algorithm (4) Project details (5) Efficient Coding on string algorithms (6) Scalability and questions on how to scale web applications (7) Networking and identifying problems in networks (8) Tree/graph traversal algorithms and applications in social area.
