Zee5 Tech Game Developer Interview: Rounds, Questions and Preparation

What the job involves

A Game Developer at a company like Zee5 Tech builds and maintains interactive games, often for mobile or web platforms, working with designers, artists, and backend engineers. Day to day, you write gameplay code, integrate assets, optimise performance, and debug issues across devices. You may also work on live-ops features, monetisation hooks, or cloud-based game services.

Role and technical knowledge

1. 1

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

   Explain the Update method, fixed timestep for physics, and how frame rate independence works. Mention the difference between Update and FixedUpdate.

2. 2

   How do you handle collisions between a player and an enemy in a 2D game?

   Cover Unity colliders, triggers, layers, and OnCollisionEnter2D or OnTriggerEnter2D. Mention tags or components to identify objects.

3. 3

   Explain the difference between a prefab and an instance in Unity.

   A prefab is a reusable asset template; an instance is a copy in the scene. Changes to the prefab can propagate to instances.

4. 4

   What is object pooling and why is it useful in games?

   Object pooling reuses objects instead of instantiating and destroying them, reducing garbage collection spikes and improving performance on mobile.

Practical scenarios

1. 5

   Your mobile game runs at 20 FPS on low-end devices. How would you diagnose and improve performance?

   Profile with Unity Profiler, check draw calls, reduce overdraw, optimise textures, use object pooling, and limit physics updates. Mention testing on target devices.

2. 6

   A level designer reports that a moving platform sometimes pushes the player through a wall. How do you debug this?

   Check collider sizes, physics timestep, and interpolation. Use continuous collision detection for fast-moving objects and test with debug visuals.

3. 7

   You need to add a daily reward system that works offline and syncs when online. How would you approach it?

   Store last claim time locally, use a server timestamp when online, and handle conflicts. Mention PlayerPrefs or a local database and a simple sync API.

4. 8

   How would you implement a simple leaderboard for a single-player game with optional online scores?

   Use a local high-score list and a backend service like Firebase or a custom REST API. Discuss data format, security, and offline caching.

Behavioural and teamwork

1. 9

   Tell me about a game you played recently and what you would improve about its design or code.

   Show analytical thinking and passion for games. Focus on one or two specific mechanics, not just graphics, and suggest feasible improvements.

2. 10

   Describe a time you had a disagreement with a teammate on a project. How did you resolve it?

   Use the STAR method. Emphasise listening, data-driven discussion, and focusing on the project goal rather than winning the argument.

3. 11

   How do you prioritise tasks when you have a bug fix, a new feature, and a deadline?

   Mention assessing impact and urgency, communicating with the team, and using tools like Trello or Jira. Show flexibility and transparency.

4. 12

   Why do you want to work in the gaming and creator economy sector, and how do you keep your skills updated?

   Connect personal gaming or modding experience to the role. Mention game jams, online courses, devlogs, or open-source contributions.

HR and company fit

1. 13

   What do you know about Zee5 Tech and its presence in gaming or interactive entertainment?

   Research the company's products, recent game launches, or streaming integrations. Show how your skills align with their tech stack or audience.

2. 14

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

   Show ambition to grow into a senior or lead role, specialise in a area like gameplay or graphics, and contribute to successful titles.

3. 15

   Are you comfortable working on games that may target a mass Indian audience with varied devices and network conditions?

   Demonstrate awareness of device fragmentation, low-end optimisation, and data-saving features. Mention testing on multiple Android versions.

4. 16

   How do you handle feedback on your code or game design from senior developers?

   Show openness to code reviews, willingness to learn, and a focus on team success. Give an example of incorporating feedback positively.
