Bulbul Live Commerce Game Developer Interview: Rounds, Questions and Preparation

What the job involves

A Game Developer at a fast-growing Indian gaming or live-commerce company builds and maintains interactive game features, often for casual mobile titles or in-app gamification such as live quizzes, rewards, and mini-games. Day to day you write gameplay code, integrate assets, optimise performance for low-end Android devices, and work with designers and backend teams to ship updates quickly. In the creator economy, you may also build tools that let streamers or users create and share simple games or interactive experiences.

Role and technical knowledge

1. 1

   What is a game loop and how would you implement a simple one in Unity?

   Explain Update vs FixedUpdate, frame independence with Time.deltaTime, and how you would structure a basic loop for movement or state changes.

2. 2

   How do you optimise a mobile game for low-end Android devices?

   Cover reducing draw calls, using object pooling, compressing textures, limiting physics updates, and profiling with Unity Profiler or Android GPU Inspector.

3. 3

   Explain the difference between a prefab and an instance in Unity, and when you would use each.

   Prefab is a template; instance is a copy in the scene. Use prefabs for reusable objects like enemies or UI elements, and instantiate at runtime for spawning.

4. 4

   How would you implement a simple leaderboard or reward system for a live quiz game?

   Discuss local storage vs backend sync, data models for scores, anti-cheat basics, and how to update UI efficiently without blocking the main thread.

Practical scenarios

1. 5

   Your game runs at 60 fps on your phone but drops to 20 fps on a budget device. How do you debug and fix it?

   Start with profiling to find CPU or GPU bottlenecks, then suggest fixes like reducing particle effects, lowering resolution, or simplifying shaders.

2. 6

   You need to add a new in-game event with limited-time rewards. How do you plan the code and assets?

   Break down into config-driven design, server time checks, UI popups, and testing for edge cases like expired events or duplicate rewards.

3. 7

   A designer asks for a feature that will take two weeks but you have three days. What do you do?

   Show prioritisation: propose a minimal viable version, communicate trade-offs clearly, and suggest a phased rollout.

4. 8

   How would you handle a bug where players sometimes get stuck in a wall after a dash move?

   Explain using raycasts or capsule casts to detect collisions, clamping movement, and adding a fallback reset if out of bounds.

Behavioural and teamwork

1. 9

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

   Focus on your specific contribution, a technical challenge you solved, and what you would do differently next time.

2. 10

   Describe a time you disagreed with a teammate on a technical approach. How did you resolve it?

   Show that you listen, use data or prototypes to compare options, and prioritise the project goal over personal preference.

3. 11

   How do you keep up with new game development tools and trends?

   Mention game jams, online courses, devlogs, or communities like Unity forums, and give a recent example of something you learned.

4. 12

   Why do you want to work in the gaming and creator economy sector, especially at a fast-growing company?

   Connect your passion for games with the idea of building engaging experiences for creators and users, and show awareness of the company's space without assuming specific details.

HR and company fit

1. 13

   What are your salary expectations for this role?

   Research typical fresher game developer salaries in India, give a range, and say you are open to discussion based on overall compensation.

2. 14

   Are you comfortable working in a fast-paced environment with changing priorities?

   Give an example from college or a personal project where you adapted quickly, and emphasise your ability to communicate and reprioritise.

3. 15

   Where do you see yourself in three years as a game developer?

   Show a mix of technical growth (e.g., mastering a specialisation like gameplay or graphics) and increasing ownership, while staying grounded in the company's needs.

4. 16

   Do you have any questions for us?

   Ask about the team's tech stack, how they measure success for a game developer, or what a typical sprint looks like, showing genuine interest.
