Amazon Interview Questions

Overview

Amazon evaluates every candidate — engineer or not — against its 16 Leadership Principles (LPs), most famously 'Customer Obsession,' 'Ownership,' and 'Have Backbone; Disagree and Commit.' Expect at least one dedicated behavioral round, plus LP-style follow-up questions woven into technical interviews. A 'Bar Raiser' — an interviewer from outside the hiring team trained to protect the hiring bar — sits in on one round and carries real veto power.

Interview Process

1. Recruiter screen
   Role fit, background, logistics.
2. Online assessment
   Coding problems plus a work-style/behavioral survey, for many SDE roles.
3. Phone/video technical screen
   1–2 coding questions and a short behavioral discussion.
4. Onsite loop (4–6 rounds)
   Mix of coding, system design (for mid-level+), and dedicated LP-behavioral interviews. One interviewer is the Bar Raiser.

What Amazon Looks For

• Customer Obsession — starting from the customer's problem, not the technology
• Ownership — thinking long-term and acting on behalf of the whole company, not just your team
• Have Backbone; Disagree and Commit — pushing back respectfully, then fully committing once a decision is made
• Bias for Action — calculated risk-taking and speed over exhaustive analysis
• Deliver Results — a track record of hitting bars despite setbacks

Practice Behavioral Questions

1. Tell me about a time you disagreed with your manager's decision.
   Use STAR. Show you raised the concern directly and with data, then committed fully once the decision was made — this maps to 'Have Backbone; Disagree and Commit.'
2. Describe a time you went above and beyond for a customer.
   Pick a concrete, measurable outcome. Amazon wants specifics ('reduced latency 40%'), not generalities.
3. Tell me about a project that failed.
   Own the failure directly — don't deflect blame. Emphasize what you learned and changed afterward ('Deliver Results' + 'Learn and Be Curious').
4. Describe a time you had to make a decision with incomplete data.
   Walk through your risk assessment and the calculated bet you made — this is 'Bias for Action.'
5. Tell me about the most complex technical problem you've solved.
   Be ready to go deep — Amazon interviewers will ask follow-up questions until you reach the edge of your understanding.

Tips

• Prepare 2–3 stories per Leadership Principle — many stories can be reshaped to answer multiple LPs.
• Use the STAR format (Situation, Task, Action, Result) and lead with the result when possible.
• For SDE II and above, expect a full system-design round sized to real Amazon-scale traffic.
