Technical Phone Screen - Game Programming Fundamentals
What to Expect
A focused technical interview conducted over the phone where you'll solve practical game programming problems. Expect to write code in C++ or C# (your choice) to implement game mechanics, handle collision detection, manage game state, or solve performance-related problems. The interviewer will discuss your approach, ask clarifying questions, and may ask you to optimize or modify your solution. Code is typically written on a shared document or IDE. The goal is to assess your foundational game programming skills, problem-solving approach, and ability to communicate technical ideas.
Tips & Advice
Ask clarifying questions before you start coding to ensure you understand the problem fully. Write clean, readable code even in a timed setting. Explain your approach before implementing. Consider edge cases and performance implications. Be prepared to discuss time and space complexity trade-offs. If you get stuck, think aloud and explain your reasoning rather than staying silent. Practice coding problems on platforms like LeetCode using game development contexts (e.g., implementing a game timer, collision detection system). For junior level, focus on clear, working solutions rather than the most optimal approach.

Technical Phone Screen - Game Engine and Tools
What to Expect
Second technical phone screen focusing on game engine knowledge and practical implementation experience. You'll discuss how you've used Unity or Unreal Engine to build specific features, debug issues, optimize performance, and integrate assets. Expect questions about engine-specific concepts, scripting systems, asset pipelines, physics engines, animation systems, and UI implementation. This may include live coding, architecture discussion, or detailed walkthroughs of how you implemented specific game features. The interviewer assesses your hands-on engine experience and ability to leverage engine features effectively.
Tips & Advice
Prepare detailed walkthroughs of 2-3 significant features you've implemented in your chosen engine. Be ready to discuss specific Unity or Unreal Engine systems you've used (Prefabs/Blueprints, Animation State Machines, Physics, UI Canvas, etc.). Discuss real optimization challenges you've faced and how you solved them. Understand the asset import pipeline, how to organize project structure, and best practices for performance in your engine. For junior level, focus on practical experience rather than deep engine internals. Be honest about what you know and don't know. Practice explaining engine concepts clearly to someone who may not be familiar with that specific engine.

Onsite Technical Interview - Advanced Gameplay Systems
What to Expect
An in-person technical interview where you'll design and implement a more complex gameplay system. This could involve implementing a complete feature (e.g., inventory system, ability system, enemy AI behavior, level progression system) from scratch. You'll be given a problem statement and have 45-90 minutes to design, discuss architecture with the interviewer, and implement a solution. The interviewer evaluates your problem-solving process, code quality, ability to ask clarifying questions, and how you handle complexity and edge cases. This tests your ability to own a feature end-to-end, which is a key responsibility for junior developers.
Tips & Advice
Start by asking questions to clarify requirements and edge cases. Sketch out a high-level architecture before diving into code. Break the problem into smaller, manageable components. Write clean, well-structured code with appropriate comments. Be prepared to modify your design based on interviewer feedback. Think about scalability even at junior level—how would your system handle different scenarios? Discuss your approach throughout rather than coding silently. For junior level, demonstrating a working solution with reasonable design is more important than perfect optimization. If you complete the basic requirements early, discuss enhancements or optimizations.

This could include questions about rendering pipelines, draw calls, texture compression, LOD systems, or frame rate optimization. The interviewer wants to assess your understanding of how graphics impact gameplay and your ability to balance visual quality with performance—crucial for developing games across mobile, console, and PC as stated in the job description. This may involve code implementation or architectural discussion.
Tips & Advice
Review rendering pipeline concepts, GPU and CPU considerations, and common optimization techniques. Understand visual quality trade-offs (resolution, shader complexity, effect detail). Be familiar with LOD (Level of Detail) systems and how to optimize asset loading. Discuss real examples from your projects where you balanced visuals and performance. For junior level, focus on practical optimization awareness rather than low-level graphics API expertise. Know the basics of how your game engine handles rendering. Be prepared to discuss mobile vs. console vs. PC optimization differences. If given code to optimize, start by profiling conceptually to identify the bottleneck before suggesting fixes.
