Fairly simple interview process of an OA and then a virtual technical interview.
Started with the first part of the OA which was a set of three technical questions that I had to enter an answer for coding competition style. You are given a set of test cases to run against so you can fine tune your answers until you pass all test cases or run out of time.
After that was a second OA section that was less technical and tried to more so to simulate a day in the life of a software engineer at Amazon. This section is more about testing you on Amazon leadership principles and are in general more beahvior focused questions, with some technical stuff like discovering a bug based on output logs mixed in.
I passed those two and moved onto the formal technical interview, which was a 45min-1 hour session with an Amazon engineer. The first chunck of the interview was more behavioral, again questions focused on Amazon's leadership principles. I came prepared for questions and made sure I had answers tailored to fit specifically with their leadership principles. The second half was a technical interview where I was given what I believe was a LC easy question. The end of that interview concluded the interview process.
