Amazon Software Engineer interview questions

I was contacted via LinkedIn. Got a phone interview with couple system engineering questions and some behavioural. On site interview was nice and interesting. Whenever I didn't know the answer interviewers tried to help me and finally we get to the answer.

I applied online and got a response one week later from Amazon's in-house recruitment team to set a date for a telephonic interview, and another week before the interview took place. It was the first round telephonic interview. The interviewer introduced themself and their role in the company, then explained the structure of the interview. The questions were relatively simple, conflict question, performance problem question, design patterns and finally algorithms. Though I have no excuse for my dismal performance in the interview, I would not recommend having an interview after hours, my brain was fried and I couldn't answer the simplest of questions! Very positive experience, but make sure you are fresh and alert.
