Collaboration & Code Quality – You are expected to treat the technical assessments as collaborative sessions. Interviewers look at how you receive feedback, how you review others' code, and how you communicate your technical decisions.

Value Alignment – Snyk places a strong emphasis on culture and values. Be prepared to share concrete examples of how you have demonstrated empathy, deep care for product quality, a customer-first mindset, and collaborative teamwork in your past roles.

The interview process at Snyk is designed to evaluate both your technical competence and your alignment with the company's collaborative culture. It typically spans four to five stages, moving from high-level conversations to deep-dive technical and system architecture assessments.

The journey begins with an initial screening call with a recruiter, followed by a conversation with the hiring manager to discuss your background and align on expectations. The core technical evaluation consists of a practical code review exercise (often initiated as a take-home task or a pre-prepared pull request) followed by a live pairing session, and a system design interview. The process concludes with a behavioral and culture fit round with senior engineering leaders.

The timeline above outlines the standard progression of stages from your initial application to the final decision. Candidates should interpret this as a guide to pacing their preparation, ensuring they dedicate equal time to coding, architectural design, and behavioral scenarios. While the exact ordering of the technical rounds may occasionally vary depending on the team or location, the overall rigor and evaluation criteria remain highly consistent.

The Pull Request (PR) Review & Live Coding

The PR review and live coding session is the most critical and distinctive stage of the Snyk engineering interview process. It is designed to simulate a real day on the job rather than testing your ability to memorize algorithmic puzzles.

You will typically be given a pull request in advance (often written in Node.js, TypeScript, or Go) to review. During the interview, you will discuss your findings with two engineers, explaining your comments, identifying bugs, and pointing out security vulnerabilities. Following the discussion, you will be asked to live-code and implement some of the improvements you suggested.

Be ready to go over:

• Code Quality & Readability – Identifying code smells, dead code, and opportunities for refactoring to make the codebase more maintainable.
• Security Vulnerabilities – Spotting common security flaws, such as input validation issues, injection risks, or insecure dependency usage.
• Functional Enhancements – Implementing concrete features on top of the reviewed PR, such as adding caching mechanisms, input validation, or parallelizing API requests.
• Advanced concepts (less common) – Optimizing tree-traversal algorithms, managing memory allocation in high-throughput services, and handling complex asynchronous flows.

Example scenarios:

• "Review this Express.js pull request, identify why it is susceptible to resource exhaustion, and implement an in-memory cache to mitigate the issue."
• "Explain how you would add robust unit tests to cover the edge cases of this dependency parser, and then write those tests live."
• "Refactor this synchronous data-fetching function to perform parallel API calls while properly handling partial failures."

System Design & Architecture

The system design interview at Snyk focuses heavily on practical distributed systems design, data flow, and scalability. Interviewers want to see how you handle real-world scale and make pragmatic engineering trade-offs.

You may be asked to design a system from scratch or walk through the architecture of a complex project you have personally built and shipped. The focus is on how services communicate, how data is persisted, and how the system handles failure modes gracefully.

Be ready to go over:

• API Design & Integration – Designing clean, RESTful or gRPC APIs that are resilient to network latency and high concurrency.
• Data Modeling & Storage – Choosing the right database technology (SQL vs. NoSQL) for graph-like data structures and high-write security event logging.
• Scalability & Performance – Implementing queuing systems, load balancers, caching layers, and rate-limiting strategies to handle traffic spikes.
• Advanced concepts (less common) – Event-driven architectures using Kafka or RabbitMQ, designing for zero-downtime deployments, and managing state in highly distributed environments.

Example scenarios:

• "Design a scalable service that processes real-time webhook events from GitHub, scans the incoming code for vulnerabilities, and alerts the user."
• "Walk us through the architecture of the most complex system you've built, focusing on a major failure point and how you resolved it."
• "Design a backend system to store and query dependency graphs for millions of projects, optimizing for fast lookup times."

Behavioral & Snyk Values

The behavioral rounds at Snyk are not a formality. Engineering managers and directors use these conversations to evaluate how you collaborate, resolve conflict, and align with the company's core values.

They are looking for engineers who are empathetic, receptive to feedback, and deeply committed to continuous learning. The interviewers will dig into your past experiences to understand how you operate within a team and how you handle challenging situations.

Be ready to go over:

• Conflict Resolution – Navigating healthy technical disagreements within a team to reach a productive outcome.
• Mentorship & Growth – Actively helping peers grow, conducting constructive code reviews, and fostering an inclusive engineering culture.
• Ownership & Accountability – Taking responsibility for production incidents, learning from mistakes, and driving post-mortem improvements.

Example scenarios:

• "Tell me about a time you had to deliver a critical feature under a tight deadline. What trade-offs did you make, and how did you communicate them?"
• "Describe a situation where you received tough feedback during a code review. How did you respond and adapt?"
• "Give an example of how you have championed code quality or testing standards in your previous engineering team."

As a Software Engineer at Snyk, your daily work will directly impact the security posture of modern application development. You will be responsible for the end-to-end lifecycle of the features and services you build.
