Amazon Sr. Software Engineer interview questions

Four interviews in the same day, one for system design, three for coding questions, each coding interview had a different goal: logical solving, algorithms, and clean coding. For every stage you will get a problem to solve and they will ask you to provide examples from your career based on something they've asked. I've found the behavior questions to be more difficult than the technical questions.

There are four rounds in total. The first half hour of each round is behavior question, all of which are classic questions, all of them are Amazon high-frequency 13 questions.
