Mobile applications are often the face of a business, and any bugs or performance issues can seriously impact the user experience. Hiring managers ask this question to understand your testing methodologies, commitment to quality, and familiarity with testing tools. Knowing how you approach testing helps them gauge if you can deliver polished, reliable, and efficient mobile apps that meet the company’s standards and serve their customers well. Interviewers ask this question to assess your experience and familiarity with the app publishing process, which is a critical part of mobile app development. It demonstrates your ability to follow platform-specific guidelines, handle the submission process, and ensure that the app meets the quality and compliance standards required by both Apple and Google.
The ‘gesture recognition’ in mobile apps refers to the ability of an application to interpret human gestures as input. The touch-based gestures like swipes, taps, and pinches enhance user interaction and provide intuitive controls inside the app. Mobile app development involves using programming languages such as Java and Kotlin for Android, and Swift and Objective-C for iOS. Each programming language offers unique features and capabilities tailored to the respective platform. The UI/UX design must be accessible and optimized for different screen sizes. The UI/UX design must reflect intuitive navigation patterns, and focus on minimalism and clarity in design.

“How do you approach testing in mobile app development?”
UI tests are also essential for verifying user interaction scenarios and visual elements. I then began examining logs and crash reports to identify any patterns or anomalies. I noticed that crashes were more frequent on certain devices running specific OS versions.
- There are a few reasons why an interviewer might ask this question to a mobile application developer.
- Additionally, the interviewer may be curious to know if the candidate has used these technologies in any previous projects, as this can give insight into their problem-solving abilities and creativity.
- The first is that mobile devices have smaller screens than desktop computers, so the app interface needs to be designed for a smaller screen.
- After identifying a few commonalities, I set up a test environment to simulate those conditions.
- This speaks to your technical skills, your problem-solving capabilities, and your ability to work within a complex technological ecosystem.
The process of submitting an app to the Apple App Store or Google Play Store involves preparing the app with appropriate metadata and submitting through the respective developer console. The app must comply with platform-specific guidelines and be tested for quality assurance before submitting for review and approval. Some of the other points of difference between iOS and Android app development include monetization methods, app distribution channels, and the greater variability in screen sizes of Android devices. You could take a similar approach when hiring an iOS mobile developer by combining TestGorilla’s Clean Code test with a handful of iOS developer tests, a motivation or critical thinking test, and a personality test. Custom interview questions are a great way to evaluate candidates’ mobile development skills, but you shouldn’t use them as your only tool for measuring individuals’ suitability for your open positions.
#4. How does a developer port an application to different platforms?
When a mobile app doesn’t perform as expected post-launch, it’s a crisis that needs a swift and efficient response. Hiring managers want to ensure you’re capable of handling such pressure-cooker situations. Your answer can shed light on your problem-solving skills, your ability to work under stress, and your commitment to delivering quality products despite setbacks. It also provides insight into your technical troubleshooting abilities and your skill in communicating with various stakeholders during crisis management. Keeping up with the ever-changing world of software development is a must for any developer.
This question aims at determining your knowledge about the implementation of push notifications, an integral feature in many apps. Your answer should show your understanding of how to configure and process push notifications. For one, it helps find out how passionate a developer is about programming and continuous learning. Programmers who don’t think about mobile development outside of the workplace will have a hard time naming resources they enjoy following — that alone is a major passion and commitment red flag. The interviewer is trying to gauge the Mobile Developer’s understanding of the mobile development landscape and where it is headed.
