Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

Tell me about a time you led the migration of a screen or module from the old View system to Jetpack Compose. What broke, and how did you handle it?

What they are checking: hands-on Compose migration experience versus theoretical familiarity

Tell me about a time you had to mentor a junior or mid-level engineer whose code didn't meet your standards. How did you handle the code review conversation?

What they are checking: whether their mentorship style is constructive and specific rather than just gatekeeping

Describe a time you had to explain a technical trade-off, like taking on technical debt to hit a deadline, to someone outside engineering. How did you frame it?

What they are checking: ability to translate architecture decisions into terms leadership or product can act on

Tell me about a coding standard or convention you pushed the team to adopt that met resistance. How did you get buy-in?

What they are checking: leadership approach to establishing standards without just dictating them

What would you do

Say you inherit a codebase with almost no automated test coverage and you're told stability is now the top priority. What's your plan for the first month?

What they are checking: ability to set testing strategy and prioritize under a mandate rather than just writing tests reactively

You're running two or three technical initiatives at once with product management pushing on timelines. How do you decide what gets your attention this week?

What they are checking: prioritization and communication skills under real delivery pressure

If a teammate disagreed with your architectural decision in a code review and made a reasonable counterargument, what would you do?

What they are checking: openness to being wrong and how they handle technical conflict as a lead

About the work

Walk me through a mobile feature you architected from scratch, end to end. What pattern did you choose, MVVM, MVI, Clean Architecture, and why that one for that situation?

What they are checking: whether the candidate can reason about architecture trade-offs rather than just naming patterns they've heard of

How do you decide what belongs in a unit test versus an integration test versus a UI test with Espresso or the Compose Test Framework?

What they are checking: depth of practical testing knowledge, not just tool names

Describe the worst multi-threaded or native bug you've had to root-cause. How did you narrow it down?

What they are checking: real debugging methodology on hard, non-obvious problems

Tell me about a memory leak or performance issue you found using LeakCanary or the Android Studio Profiler. What was actually causing it?

What they are checking: genuine hands-on profiling experience versus name-dropping tools

Have you worked with the NDK or JNI for a performance-critical component? What was the interface between the Kotlin/Java side and the native code, and what went wrong along the way?

What they are checking: actual depth with native integration, since this is listed as required but easy to overstate

This is a mission-critical, high-reliability application for public safety. What does that change about how you approach coroutines, Flow, or RxJava for async work compared to a typical consumer app?

What they are checking: whether they understand the stakes of reliability in this specific domain, not just async syntax

Have you set up or maintained a CI/CD pipeline with automated test integration, using something like Jenkins, GitHub Actions, or Fastlane? What did that pipeline actually check before a build shipped?

What they are checking: real ownership of build and test automation versus having merely used a pipeline someone else built
