Fancode Software Engineer interview questions & guide 2026

The following questions are representative of the patterns observed in the Fancode interview process. While specific inquiries may shift based on your team, these categories highlight the technical rigor and practical implementation skills expected of our Software Engineer candidates.

Javascript and Frontend Implementation

These questions test your mastery of the language fundamentals and your ability to write clean, functional code under time constraints.

• Explain the behavior of Promises in Javascript and how to handle chained asynchronous operations.
• Implement a Rate Limiter function in Javascript to restrict the frequency of API calls.

Success at Fancode requires a blend of deep technical knowledge and a pragmatic, problem-solving mindset. You should approach your preparation by focusing on how your technical choices impact the end-user experience and system stability.

Technical Proficiency – You will be evaluated on your ability to write efficient, bug-free code. Focus on mastering core language features and common design patterns rather than just memorizing syntax.

System Thinking – We look for engineers who understand how individual components fit into a larger ecosystem. Be prepared to discuss why you chose a specific database, caching strategy, or communication protocol.

Pragmatic Problem Solving – During your machine coding and design rounds, express your thought process clearly. We value candidates who can identify edge cases and propose iterative solutions.

The Fancode interview process is designed to be rigorous, focusing on your ability to handle real-world engineering challenges. It typically begins with an Online Assessment to gauge your foundational coding skills, followed by a Machine Coding round, and culminates in a System Design discussion. We prioritize candidates who demonstrate a balance between speed and architectural foresight.

This timeline shows the typical progression from initial screening to design interviews. Candidates should interpret this as a path of increasing complexity; while the early stages test your syntax and logic, the later stages evaluate your ability to think like a senior contributor who understands the full lifecycle of a feature.

Machine Coding and Implementation

This area focuses on your ability to translate requirements into working software. You are expected to deliver a clean, modular, and extensible codebase.

Be ready to go over:

• Code Modularity – Writing reusable components and services.
• Error Handling – Ensuring your application fails gracefully and provides meaningful feedback.

As a Software Engineer, you will spend your time building features that enhance the fan experience. You will work on optimizing the frontend performance of our applications, ensuring that live match data is delivered with minimal latency. Your daily work involves writing high-quality code, participating in peer code reviews, and collaborating with designers and product managers to iterate on existing features.

You will also be expected to contribute to the long-term health of our codebase by identifying technical debt and proposing improvements. Whether you are working on the core streaming engine or the interactive statistics modules, your objective is to maintain a high bar for quality and reliability.

We look for engineers who are not only technically proficient but also curious and collaborative.

• Must-have skills: Strong command of Javascript and modern frameworks (e.g., React), proficiency in data structures and algorithms, and experience with RESTful APIs.
• Nice-to-have skills: Experience with Typescript, familiarity with State Management libraries (like Redux or Zustand), and exposure to cloud infrastructure.
• Experience level: We typically look for candidates with 2–4 years of experience who have worked in high-traffic, production-grade environments.

Q: How long should I prepare for the interview? A: Most successful candidates spend 3–4 weeks focusing on Javascript fundamentals and system design patterns. Consistency is more important than cramming.

Q: What is the most common reason for rejection? A: A lack of clarity in communication during the system design round or failing to consider edge cases in the machine coding stage.

Q: Is the work culture fast-paced? A: Yes, Fancode operates in a highly dynamic sports environment. We value engineers who can adapt quickly to changing requirements while maintaining code quality.

• Think Aloud: During coding rounds, explain your logic. We care more about how you solve a problem than just getting the right answer.
• Focus on Trade-offs: In system design, there is rarely one "perfect" answer. Always explain the pros and cons of your chosen approach.
• Review your Fundamentals: Don't overlook the basics of Promises and Asynchronous Javascript, as these are frequent topics in our initial assessments.
• Ask Clarifying Questions: Before starting any task, ensure you understand the requirements. This demonstrates maturity and prevents wasted effort.

The Software Engineer role at Fancode is an exceptional opportunity to shape the future of sports technology. By focusing on your core engineering skills, practicing clear communication during design discussions, and staying grounded in the practicalities of building for scale, you will position yourself for success.

Remember that every interview is a learning experience. Use the patterns identified here to structure your study and approach the process with confidence. You are preparing to join a team that values innovation and impact; we look forward to seeing the skills you bring to the table.
