The Amazon Applied Scientist Interview

The Amazon Applied Scientist interview combines a science/ML evaluation, ML system design, coding rounds, and behavioral Leadership Principles. Amazon does not use one universal interview flow — the exact rounds, their number and their order vary by team, role, level and location. This page explains the stages that Amazon’s current public guidance and amazon.jobs observations describe for this profile as of August 2026, what each stage evaluates, and how to prepare — so treat it as a well-grounded map rather than a fixed script.

Behavioral questions run throughout the loop, not just in one round. Interviewers ask for specific past examples and probe with follow-ups to test ownership, judgment, and measurable results. Answers work best in STAR form — Situation, Task, Action (the largest part, focused on what you personally did), and Result — with honest metrics. A trained Bar Raiser from outside the team also assesses whether you meet Amazon’s hiring bar.

It depends on the role and level. Many technical loops involve several interviews covering coding/technical depth, design where relevant, and multiple behavioral Leadership Principles conversations, often preceded by an Online Assessment and/or a phone screen. We describe the documented stages rather than promising a fixed count, because Amazon deliberately varies the loop by team and level.
