OA:
Part 1: Solve two coding questions in 70 minutes. The questions were not difficult at all once you saw the trick. However, I wouldn't say the questions were trivial, especially when stressed by the time limit.
Part 2 (if you passed Part 1): Working environment simulation and workstyle assessment.
Three 45-minute rounds of virtual onsite interviews. Each round consisted of a coding challenge (LC medium) and Amazon LP questions.
LC medium-level questions during the final 3 rounds. 2/3 were graph-related.
The following metrics were computed from 55 interview experiences for the Amazon SDE 1 role in United States.
Amazon's interview process for their SDE 1 roles in the United States is extremely selective, failing the vast majority of engineers.
Candidates reported having very good feelings for Amazon's SDE 1 interview process in United States.
