Amazon Security Engineer Interview Guide

Few big tech security loops lean on behavioral evaluation as much as the Amazon security engineer interview, which asks Leadership Principles questions in almost every round. Technical rounds test judgment on small, concrete tasks, such as rating a maximum-score vulnerability on a customer-facing asset after you've asked the questions that determine its true severity. Your recruiter shares the Leadership Principles and functional competencies your loop covers, so build your prep around that list with one story or example for every topic.

This guide breaks down each stage of the Amazon security engineer interview process, what Amazon interviewers look for, and how to prepare with real example questions, actionable tips, and resources.

Amazon security engineer interview process

The Amazon security engineer interview process usually starts with a recruiter call, followed by 1 to 2 technical phone screens and a final interview loop. Amazon’s standard loop has 5 interviews, though some teams run 4.

Amazon offers the loop virtually or onsite, and the full process typically takes 3-6 weeks. Ask your recruiter early for your loop’s format and interview count so you can plan your prep around the actual schedule.

Here's what the interview process can look like:

• Recruiter screen: 15-minute call to set expectations for the process
• Technical phone screen: 60-minute interview with a senior leader on the hiring team, mixing security questions with Leadership Principles
• Interview loop: 4-5 interviews, 60 minutes each, covering Leadership Principles, scripting and security fundamentals, secure code review, and, for many teams, threat modeling. Interviews are led by the hiring manager, team members, and at least one interviewer from outside the team.
• Candid Chat (optional): 30-minute informal conversation with a volunteer from an Amazon employee-led group, separate from the evaluation and the hiring team

Amazon security engineer loops assess the competencies below. Check them against your recruiter’s list and spend most of your prep time on the ones your loop includes:

Recruiter screen

The Amazon security engineer recruiter screen is a 15-minute call that sets expectations for the rest of the interview process. Some teams also send a written questionnaire after resume review that covers relocation, compensation, and work authorization, plus scenario questions on threat modeling, code review, security testing, scripting, and AI security.

Some candidates skip the recruiter call and move straight to a technical phone screen or an online assessment. Have your technical prep underway before your first conversation with Amazon.

Before the loop, your recruiter sends the Leadership Principles and functional competencies your loop will assess, with sub-topics under each. Amazon recruiters also offer an optional prep meeting.

Interviewers look for:

• Questionnaire depth: The specificity of your written answers on threat modeling, code review, security testing, and scripting scenarios
• Real examples: Whether your answers draw on work you’ve done, including the tradeoffs you accepted
• AI security familiarity: Your working knowledge of AI security, a topic some questionnaires include
• Role and background fit: How your experience and level match the role, plus logistics such as relocation and work authorization

Recently asked questions

Here’s a real question reported by a candidate on a written questionnaire:

• Describe a threat modeling exercise you’ve performed. What were the top 3 threats, how did you mitigate them, and what tradeoff did you decide not to address?

Technical phone screen

The Amazon security engineer technical phone screen is a 60-minute interview with a senior leader on the hiring team that covers security fundamentals, secure code review, and Leadership Principles. Expect scenario-based security questions alongside 2-3 behavioral questions answered in STAR format.

Interviewers may present the scenario questions as open-ended and invite you to ask clarifying questions before you commit to an answer. Use that opening to pin down scope and context, then give your answer and the reasoning behind it.

Some screens add a short live code review in Python or Java, a walkthrough of a past project you led, or AI security questions on AI-focused teams. Practice reading code aloud in both languages, and prepare one project walkthrough that covers its security decisions and tradeoffs.

Interviewers look for:

• Contextual risk judgment: How you set severity using exposure, exploitability, and customer impact alongside the raw score
• Clarifying questions: Whether you gather the facts you need before you commit to a rating or recommendation
• Security fundamentals: Your command of networking, web application security, and core vulnerability concepts
• Risk communication: Your ability to explain a security risk in terms a business leader can act on
• Project depth: How clearly you explain the technical decisions and tradeoffs in a past project you led
• STAR structure: Whether your behavioral answers cover situation, task, action, and result, with metrics where they apply

Recently asked questions

Here are some real interview questions reported by candidates:

• A new CVSS 10.0 vulnerability affects an asset in the customer path. Rate it Critical, High, Medium, or Low, and explain your reasoning.
• What is insecure deserialization, and how would you fix it?
• What is SSRF, and how would you exploit it?

Leadership Principles interviews

Every Amazon security engineer interviewer typically asks 2-3 questions tied to Amazon's 16 Leadership Principles. In some loops, the hiring manager and an interviewer from outside the team spend their full hour on behavioral questions.

Amazon assigns each interviewer specific Leadership Principles to evaluate, and the questions focus on successes and challenges from your past roles. Prepare a distinct story for each Principle so you have enough material for a full-hour behavioral interview.

The interviewer from outside the team may be the Bar Raiser, who helps make the final hiring decision and may ask detailed follow-up questions. Know the specifics behind each story: the actions you took, the data you used, and what you’d do differently.

Customer Obsession appears throughout the loop, and Amazon counts internal teams as customers. Prepare customer stories about the service teams you advise, which count as your customers as a security engineer.

Interviewers look for:

• Customer focus: Evidence that you protect customers, including internal service teams, when a security requirement creates friction
• Decision reasoning: The what, how, and why behind your decisions, including the tradeoffs you accepted
• Measurable results: Metrics or data that show the outcome of your work
• Influence: How you persuade developers and service owners who push back on a security recommendation
• Ownership: How you account for failures and missed commitments, and what you changed afterward

Recently asked questions

Here are some real interview questions reported by candidates:

• Tell me about a time a customer asked for something that wasn't in their best interest.
• How do you convince developers who refuse to accept your security recommendations?

Scripting and security fundamentals interview

In the Amazon security engineer scripting and security fundamentals interview, you’ll write a short, practical script and answer fundamentals questions, sometimes with a peer from the hiring team. Practice writing small, complete scripts of roughly 30 lines, including imports, in the language you’ll use.

The fundamentals questions cover networking, web application security, and cryptography. Prepare to explain each concept past the definition, such as walking through a TLS handshake step by step or tracing a request from browser to server.

Interviewers may overlook minor syntax mistakes in your script when your approach is clear. Put your practice time into narrating the logic, checking inputs, and handling errors.

Interviewers look for:

• A working first version: Whether you talk through and build the simplest working version before you refine it
• Input validation: How you check inputs before the script acts on them
• Error handling: Whether the script fails safely when it receives unexpected input
• Performance and maintainability: Your reasoning about how the script would scale and how another engineer would maintain it
• Fundamentals depth: How thoroughly you explain each concept when the interviewer asks follow-up questions

Sample questions

Here are some real interview questions reported by candidates:

• How do TCP and UDP differ, and when would you use each?

Secure code review interview

The Amazon security engineer secure code review interview gives you a short code sample with several security flaws and asks you to find, explain, and fix each one. The sample may be as short as 15 lines, usually in Java or Python, and the senior engineer running the interview may also ask Leadership Principles questions.

AWS application security loops can include C samples, and a single interview might cover snippets in more than one language. If you’re interviewing with an AWS application security team, add C memory-safety flaws to your review practice.

Other samples may describe a pseudo web service with no runnable code. Practice finding flaws in a service’s design and data flow from a written description.

Some loops include 2 code review interviews or replace code review with an easy-level coding challenge. Confirm the format with your recruiter.

Interviewers look for:

• Vulnerability coverage: Whether you find the full set of flaws, including OWASP Top 10 categories and cryptographic failures
• Complete mitigations: A specific fix for every flaw you identify
• Attacker impact: How clearly you explain what an attacker could do with each flaw
• Logic and design flaws: Whether you also catch design issues and bugs that would fail at runtime

Recently asked questions

In a recent Amazon Security Engineer II loop, the review sample had several flaws, none of them obscure. A working knowledge of the OWASP Top 10, including cryptographic failures, covered every issue in the sample.

Threat modeling interview

Many Amazon security engineer loops, especially for application security roles, include a threat modeling interview where you map a system and identify how an attacker would target it. Expect a hypothetical app or connected device that you'll diagram as a data flow before you list threats and mitigations.

Interviewers may ask you to apply STRIDE by name, so practice applying each STRIDE category across a data flow diagram.

Senior candidates can also expect broader security architecture discussions that resemble system design, sometimes on a whiteboard. Prepare one architecture you can draw and defend end to end.

Interviewers look for:

• System mapping: Whether you identify components, data flows, and trust boundaries before you name threats
• Threat prioritization: How you rank threats by likelihood and customer impact
• Specific mitigations: Concrete controls for your highest-priority threats
• Risk acceptance: How you decide which risks to leave unaddressed and how you'd explain that decision

Sample questions

Here are some real interview questions reported by candidates:

• Build a threat model for a smart home security system.
• Explain the threat model of a vending machine placed in your office or university library.
• How would you design a PKI system?
• Create a threat model that aligns with a data flow diagram for a given application.

How to prepare for the Amazon security engineer interview

1. Build a story for every topic on your recruiter's list: Prepare one story or example per topic and sub-topic, and expect some overlap. Tag each story with every Leadership Principle it can cover so you can adapt it to the question you’re asked.
2. Attend the recruiter prep meeting: Use the prep meeting to confirm the topics, sub-topics, and programming languages each interviewer will cover.
3. Quantify every story: Add a metric to each answer, such as vulnerabilities remediated, time to fix, or teams that adopted a control. Amazon interviewers expect data in your results.
4. Write naive versions of common security scripts: Work through the security-themed coding challenges in Grace Nolan’s Interview Study Notes, a GitHub study guide from a Google security engineer, and add log parsing, regex, and HTTP request parsing to your practice set. Build the simplest working version of each, narrate each step, then add input checks, error handling, and a note on performance.
5. Review AI security for AI-facing roles: If the team secures LLM applications or builds AI tooling, study the OWASP Top 10 for LLM Applications and agentic risks such as prompt injection, insecure output handling, excessive agent permissions, and unauthorized tool invocation. Bring an example of how you've used or evaluated LLM-based tooling in a security workflow.
6. Review AWS security services for AWS roles: If you’re interviewing with an AWS team, review AWS security services, encryption, and cloud security best practices.
7. Run mock interviews: Test your Leadership Principles stories and a timed code review with an expert coach. Use peer mock interviews to practice STAR answers out loud.

About the Amazon security engineer role

Amazon security engineers partner with service and product teams across Amazon to design security solutions, identify risks, and build controls that protect customers with minimal disruption to the business.

Teams span Amazon Stores, Devices and Services, AWS, healthcare, and AGI and AI security, and interviewers on each team can ask about that team’s domain. Read the job posting closely and prepare examples that match the team’s focus, such as application security for Stores or cloud infrastructure for AWS.

Amazon security engineers typically:

• Design, build, and implement security solutions with broad organizational impact
• Partner with service and security engineering teams on short- and long-term security strategies
• Identify risks and develop actionable mitigating controls
• Communicate risks clearly to business and security leaders
• Track industry vulnerabilities, attack patterns, and remediation techniques

Amazon security engineer experience and education requirements

Amazon Security Engineer II postings typically require 3+ years of programming in a language such as Python, Java, Go, or C++, plus 2+ years of scripting and security code review. Most also ask for a bachelor’s degree in computer science or a STEM field, or equivalent security experience.

Preferred qualifications often include threat modeling, secure coding, and AWS experience. Offensive security teams may also prefer certifications such as OSCP.

Prepare a concrete example for each basic qualification on your posting. Interviewers can ask about the experience behind any of them.

FAQs about the Amazon security engineer interview

Is the Amazon security engineer interview hard?

The Amazon security engineer interview’s difficulty depends more on your Leadership Principles stories than on technical depth. The technical rounds use short scripts, code review, and scenario questions, and standard algorithm challenges appear only in some loops. Prepare your behavioral stories as thoroughly as your technical material: almost every interviewer evaluates them.

Does the Amazon security engineer interview include coding?

The Amazon security engineer interview includes a short scripting exercise and a secure code review, and some loops replace code review with an easy-level coding challenge. The script may fit in about 30 lines, and interviewers focus on your approach, input validation, and error handling.

Does the Amazon security engineer loop include a Bar Raiser?

Amazon Security Engineer II (L5) and senior loops typically include a Bar Raiser: a trained interviewer, usually from outside the hiring team, who helps make the final hiring decision. The Bar Raiser’s job is to confirm that each new hire is better than 50% of current employees in similar roles. Amazon has varied Bar Raiser coverage for entry-level loops. If you’re interviewing at L4, confirm with your recruiter. Assume any interviewer from outside your team may hold the role, and prepare every story with enough detail to answer several follow-up questions.

How long does the Amazon security engineer interview process take?

The Amazon security engineer interview process typically takes 3-6 weeks from application to offer. Amazon aims to share a decision within 2 business days of the phone screen and within 5 business days of the loop. If that window passes without an update, follow up with your recruiter.

Can you use AI tools during the Amazon security engineer interview?

Amazon doesn’t allow candidates to use generative AI tools during interviews unless the recruiter or interviewer explicitly permits it, and using them without permission can lead to disqualification. Some software engineering assessments now include an AI assistant. Confirm with your recruiter which tools each stage of your loop allows.

A 2026 pilot also records and transcribes some interviews, but only with your explicit consent.

How much does an Amazon security engineer make?

Here are the reported compensation ranges by level for Amazon security engineers, according to Levels.fyi:

• L4 (Security Engineer I): ~$189K
• L5 (Security Engineer II): ~$280K
• L6 (Senior Security Engineer): ~$379K
• L7: ~$488K

Amazon pays in base salary, RSUs, and sign-on payments. RSUs vest on a back-loaded 5/15/40/40 schedule, and sign-on payments offset the low vesting in the first 2 years. New RSU grants for L4-L7 now vest quarterly.
