Amazon Solution Architect interview questions

Several phone screens with team members. All were friendly and cordial. In additional to the standard questions on your background, why are you looking for a new role, etc. they asked a variety of technical questions and situational questions. What's the difference between TCP and UDP? How does DNS work? What are some examples of DNS record types? Explain an instance of a challenging situation at your current job and what was the resolution? How would you scale out a customer experiencing high traffic and slow page responses?

It was a typical Amazon Interview where after couple of phone interview, they had me fly to Seattle, WA for a full day drill. During full day interview, it was a very intense process where they had me go through 6 different interviewer - individually - with Human Resource, Technical Architects, Product Manager, Hiring Manager - to name a few. Many of the interview process was scenario based where they present some artificial scenario and ask you to come up with solution design.
