Amazon Software Engineer Interview Guide 2026
Amazon's interview process is uniquely defined by their 16 Leadership Principles, a set of values that shapes every hiring decision. Unlike companies where behavioral interviews are secondary to technical assessment, Amazon treats LP alignment as equally important to coding ability. This guide explains how to demonstrate the Leadership Principles while solving technical problems, how to navigate the Bar Raiser process, and what makes Amazon's evaluation criteria different from other big tech companies.

What Makes Amazon's Interview Different
Amazon's 16 Leadership Principles aren't corporate platitudes, they're the actual framework interviewers use to evaluate candidates. Every interview round, including technical ones, includes behavioral questions designed to assess LP alignment. An engineer who crushes the coding problems but gives weak LP answers will likely be rejected. An engineer with solid (not perfect) technical skills who demonstrates strong ownership, customer obsession, and bias for action may receive an offer.
The Leadership Principles most relevant to engineering roles include Customer Obsession (starting with the customer and working backwards), Ownership (acting on behalf of the entire company), Dive Deep (staying connected to details), and Bias for Action (valuing calculated risk-taking over analysis paralysis). You don't need to memorize all 16, but you should understand them well enough to recognize which principles your stories demonstrate.
Amazon's interview process includes a "Bar Raiser", an interviewer from outside the hiring team whose job is to maintain hiring standards across the company. The Bar Raiser has veto power: if they vote no, you don't get the job, regardless of how other interviews went. They're typically senior engineers or managers who've completed special training. The Bar Raiser interview is often (but not always) the most challenging round.
Unlike Google or Meta, Amazon's process is faster and more transactional. There's no team matching phase, you interview for a specific team and role. The hiring manager is directly involved and invested in the decision. This means less ambiguity about what you're signing up for, but also less flexibility if the team doesn't turn out to be a good fit.
The Process
How Amazon's Interview Process Works
Amazon's interview process typically takes 2-4 weeks from first contact to offer. It's one of the more efficient big tech processes, partly because there's no committee review or team matching phase. The Online Assessment (OA) serves as an initial filter, followed by phone screens and an onsite "loop" of 4-5 interviews.
Online Assessment90-120 minutes
Amazon's OA includes two coding problems and a work simulation section that assesses decision-making through scenario-based questions. The coding problems are typically medium difficulty. The work simulation presents workplace scenarios where you choose how to respond, these questions directly assess Leadership Principle alignment. Take the work simulation seriously; it's not just a formality.
Phone Screen45-60 minutes
A technical interview with one coding problem plus 2-3 behavioral questions. The interviewer evaluates both your coding ability and LP alignment simultaneously. Don't be surprised when a coding interviewer transitions to "Tell me about a time when..." questions. Both components matter equally for passing this round.
Onsite Loop5-6 hours
The loop consists of 4-5 interviews: typically 2 coding/system design rounds, 1 Bar Raiser round, 1 hiring manager round, and sometimes an additional team member round. Each interviewer is assigned specific Leadership Principles to assess. The Bar Raiser evaluates overall caliber and has veto power. All interviewers submit written feedback before the debrief meeting.
Debrief & Decision1-2 weeks
All interviewers meet to discuss your candidacy. Each person shares their hire/no-hire recommendation and the specific LP evidence they collected. The Bar Raiser ensures the bar is maintained. Hiring requires consensus, one strong no vote (especially from the Bar Raiser) typically results in rejection. Decisions usually come within a week of the debrief.
Technical Preparation
What to Study for Amazon Interviews
Coding Interviews
Amazon's coding interviews are standard LeetCode-style problems with a twist: every coding round also includes behavioral questions. You might solve an algorithmic problem and then immediately be asked "Tell me about a time you had to dive deep to find the root cause of a problem." The coding portion uses a collaborative editor; you're expected to write working code, not pseudocode.
Frequently tested topics include trees and graphs (traversals, BFS/DFS, shortest paths), arrays and hashing (two-sum variants, sliding windows, frequency counting), object-oriented design (class structure, design patterns), and string processing. Amazon also asks more OOD-style questions than Google or Meta, designing a parking lot system, an elevator system, or a library management system. These questions test your ability to translate requirements into class hierarchies.
System Design
System design interviews at Amazon often draw from real Amazon products and services. You might design a recommendation system, an inventory management system, or components of AWS. The interviewer wants to see that you can think about scale, reliability, and customer impact. Amazon builds systems that handle millions of transactions per second; your designs should reflect awareness of that scale.
Common themes include e-commerce systems (shopping cart, checkout flow, inventory management), distributed databases (DynamoDB-style key-value stores, partition strategies), delivery and logistics (route optimization, real-time tracking, warehouse management), and cloud services (designing S3-like storage, Lambda-style compute, load balancing). Connect your technical decisions to customer impact whenever possible, that's the Amazon way.
Sample Questions
LRU Cache implementationCoding
A classic Amazon question testing data structure design. You need to implement get() and put() operations in O(1) time using a hash map plus doubly-linked list. Interviewers will ask about thread safety and how you'd scale this across multiple machines.
Find the k most frequent elementsCoding
Tests your knowledge of heaps and hash maps. The optimal solution uses a hash map for counting plus a min-heap of size k. Be ready to discuss trade-offs between heap-based and quickselect approaches.
Design Amazon's product recommendation systemSystem Design
A common Amazon question testing your understanding of personalization at scale. Key topics include collaborative filtering vs. content-based approaches, real-time vs. batch recommendations, and how to handle the cold-start problem for new users.
Behavioral Assessment
The Behavioral Interview
What They're Really Evaluating
Amazon's behavioral interviews are comprehensive and structured. Each interviewer is assigned specific Leadership Principles to assess and will ask 2-3 targeted questions. They're trained to use the STAR method for evaluation, so your answers should follow that format. The interviewer will probe for specifics: Who exactly was involved? What was your specific contribution? What were the measurable results?
How to Prepare
Prepare 6-8 stories that cover the most common LPs: Customer Obsession, Ownership, Deliver Results, Dive Deep, Bias for Action, Earn Trust, and Have Backbone. Each story should have specific metrics, percentages, dollar amounts, time saved, users impacted. Practice the STAR format until it's natural: Situation (brief context), Task (your responsibility), Action (what YOU did, not the team), Result (quantified impact). Amazon interviewers will interrupt to dig deeper; this is normal.
Sample Behavioral Questions
Tell me about a time you disagreed with your manager
This assesses Have Backbone and Earn Trust. Amazon wants engineers who will push back on bad ideas, but respectfully. Describe a specific disagreement, how you handled it constructively, and the outcome, whether you won the argument or not.
Describe a time you had to make a decision without all the data
Tests Bias for Action. Amazon values speed over perfection in many situations. Describe how you gathered available information, made a calculated decision, and course-corrected if needed. Quantify the impact of acting quickly vs. waiting.
Compensation
Amazon Salary Ranges
| Level | Title | Base Salary | Stock/Year | Total Comp |
|---|---|---|---|---|
| L4 | SDE I | $115K-$140K | $20K-$40K | $150K-$200K |
| L5 | SDE II | $140K-$175K | $40K-$120K | $200K-$320K |
| L6 | Senior SDE | $175K-$220K | $120K-$300K | $320K-$550K |
| L7 | Principal SDE | $220K-$280K | $300K-$600K | $550K-$900K |
Amazon's stock vesting schedule is heavily backloaded: 5% in year one, 15% in year two, 40% in years three and four. To compensate, they offer signing bonuses that make year-one compensation competitive. The effective result is that leaving before year three means leaving significant money on the table. When negotiating, focus on signing bonus and base salary since those are more flexible than stock structure. Amazon will match competing offers but rarely exceeds them significantly.
