AR developers should be able to explain complex technical concepts in simple terms and be receptive to feedback from their colleagues and clients. They should also be able to provide clear and concise progress reports to stakeholders.
Deep Understanding of UX Design
Another aspect to consider when hiring developers is their understanding of user experience (UX) design. AR is all about creating experiences that blend the virtual and physical world, so it is important that the AR developer has a deep understanding of UX design principles and can create user-friendly and intuitive AR experiences. This includes a firm grasp of user research, wireframing, and prototyping.
Experience with Cross-Platform Development
AR developers should also be experienced with cross-platform development. AR applications must work seamlessly on multiple platforms, including Android and iOS. Hiring AR developers with experience in cross-platform development ensures that the application will function well across different devices and operating systems. This also means clients can reach a wider audience and get more value from their AR application.
Top 5 AR Developers Interview Questions
As the demand for augmented reality developers increases, hiring managers must ask relevant questions to determine the right fit for their organization. Here are the top 5 AR developers' interview questions.
Can you discuss how you have optimized AR application performance on mobile devices with lower processing power?
This is a key question for a developer because AR applications can often be resource-intensive, requiring significant processing power and memory. This can be challenging when developing mobile devices with lower processing power. A skilled AR developer should demonstrate their ability to optimize application performance to ensure the AR experience remains smooth and responsive.
When discussing this question, an experienced Augmented Reality developer should be able to explain how they have optimized application performance in the past. This might involve techniques such as reducing the complexity of 3D models, minimizing the number of textures and shaders used, and reducing the number of objects displayed on-screen at any given time.
Other optimization techniques include limiting the use of real-time lighting and shadows, avoiding unnecessary animations, and minimizing the use of high-resolution textures. An experienced developer should also be able to discuss how they have utilized techniques such as occlusion culling and LOD (Level of Detail) to optimize performance.
How do you integrate computer vision technologies with AR experiences?
This is a great interview question for an AR developer because it assesses their knowledge of computer vision and its applications in AR. An AR experience is only as good as the technology that underlies it. By integrating computer vision technologies with AR, developers can create more immersive and interactive experiences.
The answer to this question will provide insight into the developer's experience and knowledge of computer vision and how it can be used in AR. The ideal candidate should deeply understand computer vision technologies such as image recognition, object detection, and tracking. They should also be familiar with the latest libraries and tools, such as OpenCV, TensorFlow, and Caffe2, used to implement these computer vision techniques.
An excellent answer to this question should include specific examples of how the candidate has previously integrated computer vision with AR. For instance, they could describe how they used object recognition to track and identify real-world objects and then superimposed virtual objects on top of them. They might also discuss how they used image recognition to enable facial recognition and tracking in AR experiences.
How do you handle occlusion in AR experiences?
Occlusion occurs when an augmented reality experience requires virtual objects to appear behind real-world objects. Occlusion is a challenging problem that AR developers must address to create seamless, realistic experiences.
This question is essential to ask an AR developer because it demonstrates their understanding of occlusion and their approach to solving this problem. You can assess the candidate's knowledge of occlusion and ability to implement it in an AR app. The interviewer should expect a detailed response from the candidate regarding their understanding of the various techniques and tools available for handling occlusions, such as depth mapping, camera calibration, and object recognition.
A good answer from an AR developer would explain how they would use these techniques to create a convincing illusion of virtual objects appearing behind real-world objects. They may also describe any additional tools or technologies they have used to overcome occlusion challenges. This question helps ensure the AR developer has the skills and experience to deliver realistic, high-quality AR experiences to clients.
What AR SDKs have you worked with, and what are some of their advantages and disadvantages?
By asking this question, you can gain insight into the candidate's familiarity with AR SDKs and their strengths and weaknesses. Having experience working with several AR SDKs such as Vuforia, ARKit, ARCore, Wikitude, EasyAR, and Unity3D is vital. They should be able to discuss the benefits and drawbacks of at least one of the SDKs they have worked with. This is essential as it will allow you to assess the level of their experience and expertise in AR app development.
They must be able to discuss the pros and cons of various AR SDKs. Vuforia stands out because of its multiple platform compatibility, excellent tracking capabilities, and easy-to-use interface. On the other hand, ARKit and ARCore offer high accuracy and performance, and they are primarily designed for iOS and Android devices. Wikitude, known for its simplicity and ease of use, is often a developer's go-to choice. EasyAR is known for its simplicity and easy integration with Unity3D. Unity3D, famous for game development, also supports AR development, but it can take time for new developers to learn.
How do you handle tracking and detection of virtual objects in AR?
Top augmented reality developers deeply understand how tracking and detection of virtual objects work in AR. When you ask this question, you evaluate if the developer has experience with motion tracking, object recognition, and computer vision. A good answer should demonstrate a deep understanding of these concepts and how they apply to AR.
One possible answer could be that the developer uses AR software development kits (SDKs) such as ARKit for iOS or ARCore for Android, providing robust tracking and detecting real-world objects. They could also mention how they implement computer vision techniques to detect and track markers, such as QR codes or physical objects.
Another answer could be that the developer uses machine learning algorithms to train their AR app to recognize specific objects in the real world. They could discuss how they use convolutional neural networks (CNNs) to extract features from images and then use these features to train their app to recognize objects.
