Amazon Network Development Engineer interview questions

I had 1 technical phone interview, there is one phone interview for an hour and The phone interview was pretty straight forward.Debugging skills were put into test in maximum rounds

Applied via employee referral program. Very cool and supportive HR and technical interviewers. Prior the interview I was provided with detailed guidelines and recommendations. Amazon Leadership principals are very important. You have to prepare couple of examples and be very brief and straight to the point with it. As for the technical questions the first screening interview was dedicated to BGP (loop prevention, traffic engineering, iBGP RR topologies), TCP (flow control, congestion avoidance), traceroute.
