What You’ll Be Asked
Mobile testing interviews cover the full spectrum of mobile quality — from functional testing on iOS and Android to performance, battery consumption, and network condition simulation. Interviewers ask about device farm strategies (BrowserStack, Sauce Labs, AWS Device Farm), the trade-offs between emulators and real devices, deep linking, push notification testing, and mobile-specific gestures. You may also face questions about responsive web testing versus native app testing and hybrid app architectures.
Topics Covered
Key areas interviewers evaluate when asking about mobile testing.
iOS vs Android Testing
Platform-specific testing challenges — provisioning profiles, Android fragmentation, OS version coverage strategies, and app store guidelines.
Device Farms & Cloud Testing
Using BrowserStack, Sauce Labs, AWS Device Farm, and Firebase Test Lab for scalable device coverage without owning hundreds of devices.
Mobile Performance Testing
Profiling app startup time, memory leaks, battery drain, network usage, and frame rate — tools like Android Profiler and Xcode Instruments.
Responsive & Web Mobile
Testing responsive web apps on mobile viewports, touch events, viewport meta tags, and progressive web app considerations.
Emulators vs Real Devices
When emulators/simulators are sufficient vs when you need real devices — camera, GPS, biometrics, and carrier-specific behavior.
Push & Deep Link Testing
Testing push notification delivery and handling, deep links, universal links, app intents, and inter-app communication flows.
Sample Interview Questions
Questions based on real interview patterns. Practice answering these with AssertHired’s AI interviewer.
- 01
What are the key differences between testing on iOS and Android? How does this affect your test strategy?
- 02
When would you use an emulator versus a real device for testing? Give specific examples.
- 03
How would you approach testing an app across 50+ device/OS combinations with a limited budget?
- 04
Describe how you would test push notification behavior, including edge cases like the app being backgrounded or force-closed.
- 05
What metrics would you track for mobile performance testing, and what tools would you use?
- 06
How do you test deep links and universal links on both iOS and Android?
- 07
A user reports that the app crashes only on Samsung Galaxy devices running Android 13. How would you reproduce and investigate?

Frequently Asked Questions
What mobile testing topics are most asked in interviews?
The most common topics include iOS vs Android testing differences, emulator vs real device trade-offs, device farm strategies, mobile performance testing, and handling platform-specific challenges like permissions, gestures, and interruptions (calls, notifications). Automation with Appium is also frequently discussed.
Is mobile testing different from mobile automation with Appium?
Yes. Mobile testing as a discipline is broader — it includes test strategy, device selection, manual exploratory testing, performance profiling, and usability. Appium is one specific automation tool used within mobile testing. Strong mobile QA engineers understand both the strategic and tooling sides.
Do I need to know both iOS and Android for interviews?
Ideally, yes. Most companies ship on both platforms and expect QA engineers to test across both. You don't need to be an expert in Xcode and Android Studio internals, but understanding the key testing differences between platforms is essential.
Can I practice mobile testing questions on AssertHired?
Yes. AssertHired's AI interviewer covers mobile testing strategy, platform differences, device farms, performance testing, and real-world mobile QA scenarios. You get scored feedback on every answer.
