Amazon Non Software Development Engineer interview questions

I was referred for the SDE level 4 role. The process started with a call from the recruiter (15 mins). The recruiter was very patient and explained the entire process and asked basic questions about why I wanted to change my company and what are my interests. After the call, the recruiter sent me the link for the online assessment. I had 4 weeks time to attempt the test. The online assessment had 2 coding questions to be completed within 105 minutes and MCQs to gauge our personality to be completed later. I could not clear this round and I got the rejection email within 3 days of completing the test.

First : A web test in Algorithms and Data structures plus some behavioral questions. Second : One call with leadership principles questions and algorthimic and data structures questions. Thrid : 4 calls about leadership principles, algorthimic and data structures, code maintenability and extensibility and system design.
