Amazon

Had a phone screen, followed by an online assessment, and then an interview by the team lead. Was rejected after that. The screen took a half hour, the assessment took two and a half hours, and the interview was an hour.

I just did the pre-screening call, but was found that I wouldn't be a good fit for this role based on experience incompatibilities. The job was more on the AWS side, where my experience was not.

Four 45-minute rounds with a 15-minute break between each round, totaling 5 hours. Three rounds are for coding, and one is for system design. Each interview consists of 20 minutes of behavioral questions and 30 minutes of technical parts.
