Amazon Software Development Engineer, interview questions

I applied through online application process on recommendation of a friend. Got an interview call for scheduling an telephonic interview just after a week. I was not knowing much about this company before reading the reviews at glassdoor. After I read the reviews about amazon's work culture and their tedious interview process (I just dont understand why they have to take 5 technical rounds !!! ) ,I was least interested to work for this company. Anyway , On the day of the interview , I kept waiting for the call and then finally the interviewer called almost 10 mins late.It sounded like he was not much interested in taking the interview.He asked 3 technical questions in 40 mins ... one was related to object oriented design and one brain teaser and last was about some string sorting algorithm and coding. Other questions were straight from the resume . I am writing this review just to help the people having their interview scheduled ... just a note of thanks for all others who gave me an insight about the process... All the best !!

Met Amazon representative at university career fair where they had me answer a small programming question. About a week later I received an email about an interview opportunity in seattle. I had the option to choose the most convenient date out of list. In Seattle, I went through 4 technical interviews, about 45min each. They some simple algorithms questions such as tree traversals, binary search.
