Loco Game Developer Interview: Rounds, Questions and Preparation

What the job involves

A Game Developer at a gaming and creator economy company builds and maintains interactive game features, often for live mobile or web games with social and creator-led elements. Day to day work includes writing gameplay code, integrating assets, optimising performance for low-end devices, and shipping updates that keep players engaged. You collaborate with designers, artists, and backend engineers to turn game ideas into playable experiences.

Role and industry knowledge

1. 1

   What does a game developer do differently at a live-ops gaming company compared to a traditional game studio?

   A strong answer mentions frequent updates, analytics-driven decisions, live events, and working with creator or social features rather than only shipping a boxed game.

2. 2

   How would you explain the difference between a game developer and a game designer to a non-technical friend?

   Focus on developer building systems and code, designer defining rules, fun, and player experience. Show you understand collaboration between the two.

3. 3

   What are some challenges of building games for Indian mobile users with varied devices and networks?

   Cover low-end device optimisation, data usage, offline or poor network handling, and smaller install sizes. Mention testing on budget phones.

4. 4

   Why are creator economy features like user-generated content or streaming integrations important for games today?

   Talk about retention, community building, viral reach, and new revenue streams. Show awareness of how players also create and share content.

Technical knowledge

1. 5

   Explain the game loop in Unity and how Update, FixedUpdate, and LateUpdate differ.

   Mention frame-rate independence, physics timing in FixedUpdate, and camera or follow logic in LateUpdate. Give a small example of each.

2. 6

   How would you implement a simple state machine for a character that can idle, run, and jump?

   Describe states, transitions, and conditions. Mention using enums or classes and avoiding tangled if-else chains. Keep it simple and testable.

3. 7

   What causes frame rate drops on mobile, and how would you profile and fix them?

   Mention draw calls, overdraw, heavy physics, garbage collection, and large textures. Talk about Unity Profiler, reducing allocations, and object pooling.

4. 8

   How do you handle collisions and triggers in Unity, and when would you use each?

   Explain Collider vs Trigger, OnCollisionEnter vs OnTriggerEnter, and layers. Give a game example like picking up a coin versus blocking movement.

Practical scenarios

1. 9

   You are asked to add a daily reward system to a live mobile game. How would you design and implement it?

   Cover data storage, reset timing, UI feedback, anti-cheat basics, and server sync if needed. Mention testing edge cases like missed days.

2. 10

   A multiplayer feature works in the editor but lags in real matches on low-end phones. How do you debug this?

   Talk about network profiling, reducing send rate, interpolation, and testing on actual devices. Mention logging and reproducing with poor network conditions.

3. 11

   Your game crashes on some Android devices after an update. What is your step-by-step approach?

   Start with crash logs and device segmentation, reproduce on affected hardware, check recent changes, and roll back if needed. Mention communicating with the team.

4. 12

   You need to integrate a leaderboard and sharing feature so players can post scores to social media. How would you approach it?

   Discuss backend or third-party service for leaderboards, privacy, deep links, and platform-specific sharing APIs. Mention testing on both Android and iOS.

Behavioural and HR questions

1. 13

   Tell me about a game or personal project you built. What was your role and what did you learn?

   Use a clear structure: goal, your contribution, challenges, result. Highlight a specific technical decision and what you would improve.

2. 14

   Describe a time you had to learn a new tool or engine quickly for a project or hackathon.

   Show curiosity and self-learning. Mention resources used, time taken, and how you applied it. Connect it to staying updated in gaming.

3. 15

   How do you handle feedback on your code or game design from teammates or players?

   Show openness, ask clarifying questions, and focus on improving the player experience. Give an example of acting on feedback without taking it personally.

4. 16

   Why do you want to work in the gaming and creator economy sector, and why this company?
