Amazon Software Development Engineer interview questions

Submitted my resume at the departmental career fair around the end of January and got a call for an interview in the first week of February. All the interviews were on-campus.

The interviewers are quite nice. I have back to back 2 phone interviews, 45 minutes each, and 15 minutes rest between the two. Each interviewer asked me some algorithms problem, and then let me code. The problems are not very difficult, but I did not perform well so I was declined the other day.
