Use the linked documentation to check technical details. Your practical exercise: Run a recruiter-confirmed mock loop that combines syntactically correct code, edge-case tests, a scalable design, and evidence-rich decisions tied to Amazon's published principles.
The plan
Work through it in order
- 01
Map the official surface
Build a one-page map around coding and computer science fundamentals, system design, testing, and operational judgment, Leadership Principles and specific behavioral evidence. For each area, record the contract, the mechanism underneath it, and one production consequence.
- 02
Prepare answer ladders
Practice a 20-second definition, a two-minute explanation with an example, and a deeper trade-off discussion. This keeps answers useful when the interviewer changes depth.
- 03
Solve a realistic scenario
Run a recruiter-confirmed mock loop that combines syntactically correct code, edge-case tests, a scalable design, and evidence-rich decisions tied to Amazon's published principles.
- 04
Run a closed-book mock
Answer aloud without notes, draw or code the critical path, test a boundary, and check every factual claim against the primary source after the attempt.
Avoidable failure modes
Common mistakes
- Memorizing coding and computer science fundamentals terminology without explaining behavior
- Ignoring the failure modes and trade-offs around system design, testing, and operational judgment
- Reading summaries repeatedly instead of retrieving and applying the material
Before you move on
Readiness checklist
- coding and computer science fundamentals explained from first principles
- system design, testing, and operational judgment connected to a production decision
- Leadership Principles and specific behavioral evidence tested with a concrete boundary
- One timed mock reviewed against official documentation
Quick answers
Frequently asked questions
Which topics should I cover?
Start with coding and computer science fundamentals, system design, testing, and operational judgment, Leadership Principles and specific behavioral evidence. Confirm the exact role and interview format with the recruiter, then deepen the areas emphasized in the job description.
How should I use this preparation plan?
Run a recruiter-confirmed mock loop that combines syntactically correct code, edge-case tests, a scalable design, and evidence-rich decisions tied to Amazon's published principles. Explain decisions aloud, test an edge case, then check the result against the linked documentation. Repeat the exercise with one changed constraint after feedback.
