Amazon Leadership Principles Interview Questions with STAR Answers

Amazon is the company where "tell me about a time when..." is not a warm-up but the main event. Every interviewer in the loop is typically assigned particular Leadership Principles to evaluate, and the coding and design rounds usually include behavioral time as well.

Check Amazon's current jobs site for the up-to-date principle list and any changes to the interview process. We describe the typical pattern here.

How the loop usually works

• Online assessment and/or phone screen
• A loop of several interviews, each with a technical component plus behavioral questions
• A Bar Raiser among the interviewers
• Debrief and a hire/no-hire decision across interviewers

Because each interviewer asks you about different principles, repeating the same story across rounds is a risk. Build a bank.

The principles that come up most for engineers

Principle	Typical question
Customer Obsession	Tell me about a time you went beyond the spec for a user
Ownership	Tell me about something you owned that wasn't your job
Dive Deep	Tell me about a time you debugged a hard problem to root cause
Deliver Results	Describe a deadline you were at risk of missing
Bias for Action	Tell me about a decision you made with incomplete data
Invent and Simplify	Tell me about a time you simplified a process or system
Earn Trust / Have Backbone	Tell me about disagreeing with your manager or team
Learn and Be Curious	Tell me about learning a new skill quickly

A worked STAR example (Dive Deep + Ownership)

Question: Tell me about a time you debugged a difficult production problem.

• Situation: Our checkout API's p99 latency doubled after a release. Two teams assumed it was the other's service.
• Task: As the on-call engineer, I owned finding the cause and restoring performance within the week.
• Action: I pulled traces and saw latency concentrated in one query. I compared query plans before and after the release and found a missing index caused by a migration order bug. I wrote a fix, added the index, and added a regression check to the migration pipeline. I also wrote a short post-incident review.
• Result: p99 returned to the previous level within a day, and the new check caught a similar issue two months later. What I'd do differently: add latency alerts per endpoint earlier.

Note the first person, the specific actions, the numbers (use your real ones), and the learning.

Build a story bank in an evening

1. List 8 events: a project you led, a failure, a conflict, a tight deadline, a simplification, a customer problem, something you learned, a decision under uncertainty.
2. Write each in STAR form with real numbers.
3. Tag every story to two or three principles.
4. Prepare the follow-ups: What was your exact role? What did others think? What would you do differently?

Mistakes that cost offers

• "We did X" with no clear personal contribution
• No measurable result
• Blaming others in conflict stories
• A story with no learning
• Inventing details. Amazon interviewers probe until the detail runs out

More questions by principle

Principle	Question to rehearse
Customer Obsession	Tell me about a time you used customer feedback to change what you built
Ownership	Tell me about a time you took on something outside your job description
Invent and Simplify	Tell me about an idea that made a process meaningfully simpler
Are Right, A Lot	Tell me about a decision you made on limited data and how it turned out
Learn and Be Curious	Tell me about a time you taught yourself something to solve a problem
Hire and Develop the Best	Tell me about how you helped a teammate grow
Insist on the Highest Standards	Tell me about a time you refused to ship something that was not good enough
Think Big	Tell me about a time you proposed something much larger than expected
Bias for Action	Tell me about a time you had to decide quickly without all the information
Frugality	Tell me about a time you did more with fewer resources
Earn Trust	Tell me about a time you admitted a mistake to your team
Dive Deep	Tell me about a time you found the root cause of a hard problem
Have Backbone; Disagree and Commit	Tell me about a time you disagreed with a decision and what you did next
Deliver Results	Tell me about a time you delivered under serious constraints

Check Amazon's current principle list and wording on its jobs site before you prepare. Amazon has revised the list over time.

A second worked example (Have Backbone + Earn Trust)

Question: Tell me about a time you disagreed with your manager.

• Situation: My manager wanted to ship a feature with no load testing to meet a launch date.
• Task: I was responsible for the service's reliability and believed the risk was too high.
• Action: I wrote a one-page note with the failure scenarios and a cheaper plan: a two-day load test on the riskiest endpoint plus a feature flag for rollback. I presented it in our planning meeting, listened to the schedule concerns and agreed to ship behind the flag once the test passed.
• Result: The test found a connection-pool limit that would have caused errors at launch. We fixed it, launched one day late, and the flag let us ramp traffic safely. I learned to bring a concrete alternative rather than only an objection.

The follow-ups interviewers use

Expect probing like:

• "What exactly did you do versus the team?"
• "What was the measurable outcome?"
• "What would you do differently?"
• "How did the other person react?"
• "What data did you use to decide?"

Prepare each story to survive at least four of these.

Using the story bank across a loop

A loop has several interviewers, often each assigned particular principles. Plan which story goes where so you do not repeat one. Keep a spare story for each of Ownership, Dive Deep and Deliver Results, because those come up most for engineers.

Mixing behavioral with technical rounds

Behavioral questions are often asked at the start or end of coding and design rounds. Keep answers to about two minutes, then stop and let the interviewer follow up. See also 30 behavioral questions for software engineers and Google's process for comparison.

Sources and freshness

This guide is based on publicly shared candidate experiences and the companies' own careers pages, last reviewed in October 2026. Amazon changes its process, test names, cutoffs and role bands regularly, and these differ by team, level and city. Treat the structure here as a typical pattern and let your recruiter's email override anything we say. If you notice something out of date, tell us and we will correct it.
