The first step was an OA with LC medium questions.
The second step was a "Day in the life at Amazon" type assessment where how you handle different situations as an SDE at Amazon is evaluated.
The third (and final) step was a live interview. 45 minutes. 30 minutes of coding (1 problem), 15 minutes of behavioral (2 questions).
Overall terrible experience, live interviewer barely spoke English which prevented me from being able to comprehend his questions, leading me to not do as well as I could have. The coding question was easy but the interviewer kept asking me questions about it I could not answer because I could not decipher what was being said. The behavioral section covered the Amazon leadership principles, need to prepare stories ahead of time to do well.
