Amazon Advertising Security Engineer interview questions & guide 2026

The questions provided below represent patterns observed in recent Security Engineer interviews. While the specific technical focus may vary by team, you should expect a consistent emphasis on practical application and the ability to articulate your security philosophy using the STAR method.

Technical & Domain Knowledge

These questions test your foundational understanding of security protocols and your ability to apply security concepts to real-world scenarios.

• Working of TLS, PKI, and common vulnerabilities.
• Describe a real threat modeling exercise you performed. What were the top three threats you identified, how did you mitigate them, and what was one security tradeoff you decided not to address?

Preparation for this role requires a dual focus: deep technical proficiency and an unwavering alignment with Amazon’s Leadership Principles. You must be able to demonstrate not just "what" you did, but "how" you navigated complex technical trade-offs while maintaining security integrity.

Technical Competency – You will be evaluated on your ability to apply security principles to code, systems, and architecture. Be prepared to discuss your methodology for manual code reviews and how you approach security testing in a fast-paced environment.

Problem-Solving & Trade-offs – Amazon Advertising operates at massive scale; there is no such thing as perfect security. Interviewers look for your ability to identify risks, quantify their impact, and make defensible decisions about which threats to prioritize and which to accept as residual risk.

Leadership & Behavioral Fit – You will be assessed on how you influence engineering teams to adopt security best practices. Using the STAR method (Situation, Task, Action, Result) is mandatory to provide clear, data-driven examples of your past leadership and collaboration experiences.

The interview process at Amazon Advertising is designed to be rigorous, structured, and consistent. It typically begins with an online application and a recruiter screening call, which serves as an initial assessment of your background and interest in the role. Following this, you may encounter an online technical assessment before proceeding to a series of technical interviews.

These interviews are conducted by panels that evaluate your core engineering skills, security domain expertise, and your alignment with the company’s culture. You should expect a mix of technical deep-dives—such as threat modeling or code review exercises—and behavioral rounds that probe your past performance through the lens of our core values.

This visual timeline tracks your progression from the initial recruiter screen to the final panel rounds. Use this to pace your study schedule, ensuring you have allocated enough time for both deep technical review and practicing your STAR method stories.

Threat Modeling & Risk Assessment

This area is the cornerstone of the Security Engineer role. You are expected to demonstrate a systematic approach to identifying and mitigating risks before they reach production.

Be ready to go over:

• Identifying attack vectors in distributed systems.
• Documenting threat models and explaining them to non-security stakeholders.
• Risk acceptance and mitigation strategies.

Example scenarios:

• "Walk me through the threat model for a hypothetical microservice."
• "How do you decide when a security control is too expensive for the risk it mitigates?"

Secure Coding & Infrastructure Security

You will be tested on your ability to find vulnerabilities in code and design secure infrastructure.

Be ready to go over:

• Common web vulnerabilities (e.g., injection, cross-site scripting).
• Security in the development lifecycle (CI/CD security).
• Automation of security testing.

Example scenarios:

• "Review this snippet of code and identify potential security flaws."
• "How do you integrate security testing without slowing down a release pipeline?"

As a Security Engineer, you will spend your time conducting security reviews, building internal security tools, and collaborating with software engineers to "shift left" on security. You are not just an auditor; you are an enabler of secure development.

You will often find yourself acting as a consultant for product teams, helping them navigate complex security requirements for new features. This involves performing regular threat modeling sessions, participating in incident response efforts, and driving the adoption of security-focused coding standards across the organization.

A successful candidate for this role possesses a blend of deep security knowledge and the ability to work within a large-scale engineering organization.

• Must-have skills:

• Proficiency in at least one modern programming language (e.g., Python, Java, or Go).

• Deep knowledge of TLS, PKI, and common network protocols.

• Experience with manual code review and threat modeling methodologies.

• Ability to articulate security concepts to technical and non-technical stakeholders.

• Nice-to-have skills:

• Experience with AI security and securing machine learning pipelines.

• Familiarity with cloud-native security tools and infrastructure-as-code.

• Background in security research or bug bounty programs.

Q: How long should I spend preparing for the interview? A: Most candidates dedicate 3–5 weeks of focused preparation. This allows enough time to review core security principles and practice articulating your past projects using the STAR method.

Q: Is the technical interview purely coding? A: Not necessarily. While you should be comfortable with data structures, the technical rounds are heavily weighted toward security-specific tasks like threat modeling, system design, and security architecture.

Q: What is the most common reason for not passing the interview? A: Candidates often struggle when they fail to connect their technical answers to the business context or neglect the behavioral portion of the interview. Always explain the "why" behind your technical decisions.

• Own your stories: Ensure every STAR example has a clear, measurable result. Numbers and metrics add credibility to your accomplishments.
• Think at scale: Always consider how your solution would perform if the traffic increased by 100x.
• Be transparent: If you don't know an answer, admit it, but walk the interviewer through your thought process on how you would find the answer.
• Practice your communication: Practice explaining complex technical concepts to someone who is not a security expert.

The role of Security Engineer at Amazon Advertising is both challenging and rewarding, offering the chance to work on systems that define the modern digital economy. Success in this process is rooted in your ability to combine deep technical intuition with a methodical, collaborative approach to security.
