How to become a Android Engineer
Build native Android apps in Kotlin: UI, lifecycle, data and a published artefact.
Best for
Students who want their work on a device they can hand to someone, and who like working within real constraints of battery, memory and network.
Maybe not for you if
If you want the widest set of campus openings, web and backend paths typically have more. Pick this because you want it, not as the safe volume play.
The 4 phases
What each phase gets you to. The steps, resources and checkpoint inside each one open with a free account.
Phase 1 - Kotlin, memory and coroutines
4-5 weeksGoal: Write idiomatic Kotlin, model state with types, and run concurrent work that cancels cleanly.
3 steps · ends in a scored checkpoint (60% to clear) · assumes basic programming
Phase 2 - Compose, lifecycle, data and offline
6-8 weeksGoal: Build a multi-screen app whose state survives rotation and process death, and that stays useful with no network.
5 steps · ends in a scored checkpoint (60% to clear)
Phase 3 - Ship it
5-6 weeksGoal: Publish an app or produce a signed, installable build with a demo, backed by tests and measured performance.
4 steps · ends in a build deliverable
Phase 4 - Clear the process
4-5 weeksGoal: Pass the standard coding and written rounds, then win the Android specific round on top.

What hiring actually looks like here
Android hiring is commonly portfolio-driven: a published app usually carries more weight than a listed skill. Campus processes still typically run the standard DSA and aptitude rounds.
