Amazon Web Services Software Development Engineer (SDE) I interview questions

The process consisted of one long homework assignment as the initial screening. Once passed, I was invited to a single interview day divided into two rounds: Round 1: Conducted by two interviewers. Round 2: Conducted by a Senior Developer. Both rounds followed a similar format, each including 2 behavioral/personal questions followed by 1 coding/technical question.

Stage 1 — Application You apply through the Amazon Careers portal (AWS roles route through Amazon University Talent Acquisition for new grads). New grad postings tend to open in waves, with a lot of activity in fall and again in winter/spring.Stage 2 — Online Assessment (OA) Within 1–2 weeks of applying, you'll typically get an OA link with a few days to complete it. It usually has two parts: two coding problems (often one easy + one medium, leetcode-style, focused on data structures and algorithms), followed by a work simulation / work-style assessment where you respond to email-style scenarios that probe how you'd handle real workplace situations against Amazon's Leadership Principles.Stage 3 — Phone screen (sometimes) Some candidates report a single technical phone screen between the OA and the final loop, but many go directly from OA to the virtual onsite.Stage 4 — Virtual Onsite ("the Loop") This is the main event: typically 2–3 back-to-back interviews, each 45–60 minutes. Each round generally follows the same pattern — roughly half behavioral, half technical:
