Amazon Software Engineer interview questions

in 2010, I got two phone interviews. Failed miserably at the second. Honestly, I was not prepared to be asked about a lot of data structure and algorithms questions. That was my second interview after graduation with Ph.D. In Ph.D. training, it is about research (for papers) and I never really cared about how fast my research code runs, since it is not on large scale data. If I had known they care so much about coding, I would have just studied the course just like it is the most important course in the world.

Hiring process started from Linked In, they contacted me first via email, we confirmed time for phone interview. I was interviewed by 2 Indians whose English was so terrible that I couldn't even understand their email address. questions was mostly easy main focus was on OOP.and data structures There was 2 programing assignments and few theoretical questions. Average time of each interview was about 1 hour.
