The interview process is challenging, not difficult, but certainly more than average. The initial HR screening call is fast-paced. I've read that Amazon prefers candidates to speak actively without too many pauses, so I kept a good pace. They look for a story, results & how you improved processes, and I had all of that ready. It was a 30 minute call, and the next day I received an online assessment to complete before moving on to the 2nd interview, which would also be the last interview with the hiring manager. I took the time to practice for the assessment, completed it after two days, and the following day I scheduled my final interview. It was a call with the hiring manager (an EA) and another EA in the office. It was very smooth, friendly and very professional.
