About the role
This interview is for an early-career developer working on native Android applications. The panel is looking for Kotlin basics, awareness of the Android lifecycle and practical decisions for unreliable connectivity and different devices. Strong answers connect code choices to what the user experiences.
How to prepare
- Revise Kotlin null safety, collections, functions and asynchronous work.
- Review activity and screen lifecycle behaviour, state restoration and navigation.
- Practise explaining how an Android screen fetches, stores and displays API data.
- Test a project with slow connectivity, denied permissions and interrupted navigation.
- Prepare to explain one crash or mobile bug you investigated.
Common mistakes
- Describing only the normal path on a reliable connection.
- Ignoring lifecycle changes and assuming a screen remains in memory.
- Blocking the interface while network or storage work completes.
- Claiming broad device support without describing how you tested it.
