The first step is to complete an online assessment (OA) assignment. If you pass this stage, you will move on to LeetCode-style coding challenges that test your problem-solving and algorithmic skills. Afterward, you will be evaluated through an object-oriented design (OOD) exercise, followed by a system design interview that assesses your ability to architect scalable and efficient solutions for complex software systems.

Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round.
The interviews were 50 mins each.
First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long. The 4 interview questions they asked where three medium leetcode questions. And one system design interview question about how to shadow deploy a test software to millions of users.
Recruiter reaches out after applying through Amazon careers, no referral. Had an initial OA, then after a month had four rounds in two days - three coding one system design. Each round had 30 min behavioral and 30 min coding.
