The following questions represent the core competencies and technical expectations for Full Stack Engineer candidates at Sundew. While specific questions vary based on the team's current focus, these categories reflect the recurring patterns found in our evaluation process.

Technical Proficiency and Full Stack Development

These questions assess your depth of knowledge in modern web frameworks, API design, and database management.

• How do you optimize the performance of a React application with a complex state?
• Explain your approach to designing a RESTful API that is both secure and scalable.

Preparation for Sundew requires a blend of rigorous technical review and clear, structured communication. Focus on demonstrating not just that you can code, but that you understand the "why" behind your technical choices.

Technical Depth – You must demonstrate mastery over your primary language and framework. Interviewers look for candidates who understand the underlying mechanics of the tools they use rather than just relying on library abstractions.

System Thinking – You will be evaluated on your ability to see the "big picture." Always consider scalability, security, and maintainability when discussing your past projects or hypothetical system design scenarios.

Collaboration and Communication – As a Full Stack Engineer, you are a bridge between teams. You should be able to explain complex technical trade-offs to non-technical stakeholders and demonstrate a collaborative, ego-free approach to problem-solving.

The interview process at Sundew is designed to evaluate your technical aptitude, your systemic problem-solving skills, and your alignment with our engineering culture. We prioritize a deep understanding of core fundamentals over the rote memorization of algorithms. You can expect a rigorous experience that challenges you to think critically about real-world engineering scenarios.

Our process is highly collaborative, often involving multiple touchpoints with engineers and product leaders. We aim to understand how you function within a team and how you approach the iterative nature of software development. You will find that our interviewers are interested in your thought process as much as the final solution.

This visual timeline illustrates the typical journey from your initial screening to the final technical and leadership discussions. Candidates should use this to pace their study, ensuring they have refreshed their knowledge of system design principles and behavioral examples before the later-stage rounds. Note that the duration and number of steps may adjust based on the specific team's needs and the seniority of the role.

Frontend Engineering

We look for candidates who can build performant, accessible, and responsive user interfaces. Mastery of modern frameworks is essential.

• State management – How you handle complex data flows in the browser.
• Component architecture – Building reusable and testable UI elements.
• Performance optimization – Reducing bundle sizes and improving rendering speeds.

Backend and API Development

Your ability to design robust server-side logic is paramount. We focus on security, scalability, and clean code.

• API design – Creating intuitive, version-controlled endpoints.
• Database design – Choosing the right schema and storage engine for the use case.
• Authentication and Security – Implementing industry-standard security protocols.

System Design

This area tests your ability to build systems that can grow with Sundew.

• Scalability – Handling increased load through caching, load balancing, and partitioning.
• Trade-offs – Clearly articulating why you chose one technology or pattern over another.
• Resiliency – Designing for failure and ensuring system uptime.

As a Full Stack Engineer at Sundew, your primary responsibility is the delivery of high-quality, scalable code that powers our user-facing products. You will be expected to own features from the initial design phase through to deployment and monitoring. This involves writing clean, well-documented code that adheres to team standards and participating in code reviews to maintain high quality across the engineering organization.

You will collaborate closely with product managers to define requirements and with other engineers to ensure architectural consistency. Beyond coding, you will play an active role in debugging production issues, optimizing existing systems for performance, and mentoring other team members to elevate the collective skill set of the engineering group.

A successful candidate for the Full Stack Engineer role at Sundew typically possesses a strong background in software development with a focus on web technologies.

• Must-have skills: Deep experience with modern JavaScript/TypeScript frameworks (e.g., React, Vue, or Angular), proficiency in server-side languages (e.g., Node.js, Python, or Go), and strong working knowledge of relational or NoSQL databases.
• Nice-to-have skills: Experience with cloud infrastructure (AWS/GCP), containerization (Docker/Kubernetes), and CI/CD pipeline management.
• Experience: Candidates should have a proven track record of shipping production-grade software and working in an agile, fast-paced environment.
