Amazon Software Engineer interview questions

The interview process consisted of an initial technical phone interview, followed by a 'homework' assignment ( design a deck of cards and implement a shuffle function). The interviewer reviewed my resume and skills with me and the focus of the interview technical questions was on object oriented design and data structures and unix/linux knowledge/skills. I enjoyed the first interview and completed the assignment. After a few days, I was scheduled for a second phone interview, which did not go well at all. I think I did well on some of the technical questions, but didn't do well for a few questions ( what is a formula to calculate the angle between the hour hand and minute hand for a clock, and design an object oriented elevator system). I did not enjoy talking to the second interviewer ( she seemed to talk down to me a little) and found her a little hard to understand sometimes. I got a rejection email a couple of days later. It helps to think aloud through these problems during the interview so they can understand your thought process. Overall, I think the interview process prepared me for similar positions I am interviewing for currently. Good luck!
