Amazon had two round R1. online test which had questions from C and Data-structure R2. Shortlisted candidate were called for interviews 2 round of interview both completely technical They ask you a question for which you have to write a complete working code. Again only your knowledge of DS and Algo can get you through. Perception: Hiring team was very casual. Most of them looked more like hackers rather than programmers.
