Seasoned Unity game developers should know the main components of Unity 3D. Can they name the main five?
Applicants should mention the following features when responding to this interview question:
Hierarchy: The hierarchy displays every GameObject in a list.
Game view: The game view option lets developers view the game and make changes to it as they play in real time.
Scene view: The scene view is a 3D preview of the open scene. Here, developers can add and manage GameObjects.
Project window: The project window is ideal for complex games. Game developers can use the project window to find game assets in a directory for all models, scripts, and prefabs.
Toolbar: The toolbar contains various tools for the game and scene windows.
Some of the three critical skills for Unity developers include strong programming knowledge, attention to detail, and knowledge of different databases and frameworks. Ensure applicants fully understand why these skills are essential for successful game development.
They should also know that the platform features an asset store where developers can access and buy the required features for their games. With Unity, it’s also possible to adapt games to various operating systems.
There are some disadvantages to using Unity 3D. For example, applicants may mention that the graphics quality isn’t as good as Unreal Engine’s. They may also mention that the interface isn’t user-friendly and explain that superior programming knowledge is essential for developers who use Unity.
Some soft skills Unity developers need to be successful include excellent communication skills to connect effectively with clients, critical thinking skills to process complex information, and numerical skills to understand statistical data.
Ask game developers these 14 Unity interview questions to review their knowledge about the technical features of the game engine.
What are the main differences between UE4 and Unity 3D?
Explain what Unity 3D files are.
Explain what the Fixed timestep is in Unity 3D.
Explain what AssetBundle does in Unity 3D.
Explain what the inspector feature does in Unity 3D.
Explain what a vertex shader is.
Explain what a pixel shader is.
What does the hierarchy panel do in the Unity editor?
What does the project panel do in the Unity editor?
What does the hierarchy panel do in the Unity editor?
Explain what DAU means.
Explain what MAU means.
Explain what prefab does in Unity 3D.
Explain what the inspector does in Unity 3D.
Look at the five sample answers to these Unity interview questions below to review your applicants’ responses and assess their technical knowledge.
Knowledgeable candidates should know that DAU means Daily Active Users. This is a metric that online Unity game developers use to determine the number of players who access their games daily.
Are applicants aware of why tracking this data is essential over time? For instance, do they know that this method is a reliable measurement of game traction?
Expert Unity developers should know that MAU means Monthly Active Users. This is a metric that Unity game developers use to assess how many active players access their games each month.
Do applicants know that, compared with MAU, DAU tends to be the more accurate metric for determining game traction?
Can your applicants explain that Unity developers use vertex shaders to apply matrix changes and complete various other operations? The script controls the vertex’s location in a 3-dimensional space and determines how it’s projected.
Skilled applicants should know that pixel shaders are scripts that run pixels or fragments that will be rendered. A gaming developer can change the color that gamers see on the screen with the pixel shader, which will set the contrast and brightness of every fragment.
Experienced Unity game developers who have used Unity3D should know that a Unity 3D file is a game archive. Can they explain that a web browser uses the game archive with a plugin to play a 3D game that developers create in Unity?
Your applicants must also know what the Unity 3D files contain. Can they explain that these files contain a lot of data and assets, including animations and sounds, models, and textures? Do they know that the 3D files contain all essential game data?
Here are five situational Unity interview questions and answers to help you review how your applicants handle challenging tasks as Unity developers.
Candidates keen on joining your organization should know that vector normalization ensures a vector retains the same direction but that developers can set the length to one.
Your applicants may mention various errors they have made when using Unity 3D. One such example is making coding mistakes during game design.
Can your applicants explain how they run tests to rectify such errors? Some of the steps they may mention are to:
Plan the test by asking the right questions and acknowledging features that developers cut
Prepare for the testing phase by putting the documents together and establishing test environments
Find errors by completing the testing process and checking the reports for the required details
Complete bug repairs when they find the bug or coding error by discussing it with the development team
Skilled applicants will understand how to hide a game object in Unity 3D. Can they explain that a certain code is required? If they’re proficient Unity developers, they should know that the code game object.transform.SetActive(false) is the best method to achieve this.
Tracking the following three metrics can help Unity game developers evaluate project success when making games:
Revenue: Your applicants should know that monitoring whether players make in-game purchases or watch ads is one way to track project success.
Retention: Candidates should know that if players are engaged or returning to a game, this demonstrates project success over time
Reach: Interviewees should know that if the number of new players or base scales increases over time, this is another indicator of project success
Do your applicants know that there are a few different programming languages Unity game developers can use for game development?
To help you perfect the interview and hiring process, we’ve compiled five tips for interviewing applicants and making the most of our list of Unity interview questions.
Take a look before beginning the interview phase.
Before you invite Unity developers to an interview, there’s an important step you should take to review their skills objectively: Use a Unity test to benchmark their skills and learn how suitable your applicants are for your gaming developer role.
Wondering when to administer a Unity skills test?
The best time is immediately after a developer applies for your position. Send them a request to complete the skills test as soon as they respond to your job ad.
Instead of checking an applicant’s resume, consider checking their portfolio and skills test results. This hiring method is better than resume screening for two reasons:
Resumes give an incomplete picture, while skills tests are accurate and objective
A portfolio will give you additional data you can use to match your candidates’ practical gaming development skills to your projects
Once you’ve checked your applicants’ portfolios, you can ask candidates for more information about their work during the interview. Enthusiastic applicants will walk you through their portfolios and share their passion. They will also have other projects in the pipeline that they’re eager to start working on.
Make sure you use the same Unity interview questions for every applicant and ensure you ask questions in the same or similar order. Or, otherwise said, use structured interviewing.
Why is it essential to use this approach when interviewing gaming developers? It’s a fairer, more objective, and legally sound method for conducting interviews, and structured interviews are much easier to plan, organize, and review.
Next, review your applicants’ Unity skill test results and interview responses. Discuss your observations with other hiring managers and recruiters in your team to unanimously decide who best matches your organization.
When you onboard your new gaming developer, skills test results can help you. For example, you may have noticed that your best applicant needs to improve their C# knowledge. Or that they’re unfamiliar with the metrics you use to track the success of the games you develop.
Use this knowledge to your advantage. Create training sessions based on this information to easily onboard your candidate and help them get productive faster.
The next Unity developer you hire will play an important role in helping you roll out engaging and flawless games – which is why you must hire carefully.
Our Unity skill test is the best option for learning about your candidates’ skills, and asking the right Unity interview questions is another crucial step.
