Mobile development assessment tests for hiring

What the mobile development tests cover

The six tests focus on practical development for Android and iOS apps, using native and cross-platform approaches. Android Development Using Java covers lifecycle and threading, screens, networking and storage, testing, and debugging. Android Development Using Kotlin assesses concurrency and architecture, UI state, networking and local data, testing, and debugging.

For app services, Firebase covers Authentication, Cloud Firestore and its security rules, Cloud Functions for Firebase, and Firebase Cloud Messaging, using short code. The cross-platform tests address different frameworks: Flutter measures Flutter and Dart knowledge, including widgets, layouts, packages, state, and app structure. Ionic Framework With React covers page structure, navigation, lifecycle, components, device features, building, and debugging. React Native covers screens, React state and effects, Android and iOS, and day-to-day workflow. All six are intermediate, 10-minute, multiple-choice tests.

Choose tests for the role and level

For an intermediate Android developer or engineer, choose the Java or Kotlin test that matches the role's language. Both focus on practical Android work. The Java test also suits Java programmers moving into mobile work, and the Kotlin test suits Kotlin programmers working on apps. The Android tests also fit mobile application developers and technical roles that review or integrate Android code.

For an intermediate mobile or cross-platform app developer, consider Flutter for Flutter and Dart work, or React Native for React Native app development. The Flutter test also suits front-end developers moving to Flutter and full-stack developers maintaining Flutter apps. React Native suits developers moving from web React or native Android or iOS work.

Choose Ionic Framework With React for front-end or mobile developers building or maintaining Ionic apps in React for Android and iOS, including React web developers moving into hybrid mobile work. For a mid-level developer who builds or maintains apps on Firebase, consider Firebase; its stated audience includes web, mobile, backend, and full-stack developers, as well as technical leads.

Combine tests around the work

Start with the framework or language named in the role's responsibilities. For native Android work, use either the Java or Kotlin test that matches the codebase. For cross-platform work, select the relevant framework test: Flutter, Ionic Framework With React, or React Native. Add Firebase when the role calls for building or maintaining apps on Firebase; the test measures Firebase services and security rules through short code.

You can combine tests when the role spans more than one of these areas. For example, an Android role that also uses Firebase could pair the matching Android test with the Firebase test. A React Native role that includes Firebase work could use those two tests, while a role maintaining Flutter apps and Firebase could use the corresponding tests. These are all intermediate assessments, each taking 10 minutes and using multiple-choice questions.

Treat each score as evidence for a person to review, not as a pass mark or a decision on its own. Consider what each assessment measures alongside the role's actual requirements. Choose only the tests relevant to the work being hired for, and review the results in that context.

How the tests are kept fair

The fairness measures differ by test. The Java Android test uses neutral app situations such as task lists, bookings, inventories, and fitness logs. Its questions use plain wording, short code, and ask about one working-developer decision rather than a rarely used detail. Scratch paper is allowed for every candidate. The Kotlin Android test uses short code and neutral variable and screen names; it states versions when behavior depends on them and gives every candidate the same 40 seconds per question.

Firebase questions use neutral app scenarios, short and plainly formatted code, and simple English. They avoid recently changed details that a skilled developer could not be expected to know. Flutter questions use short, plain stems and neutral app situations; they do not depend on a particular device brand or operating system. Ionic Framework With React questions use short code snippets and name versions where behavior differs; they do not turn on a typo or formatting trick.

React Native questions use plain identifiers and everyday app scenarios, with short plain-English wording. They do not depend on memorizing release numbers, rarely used command flags, or one company's in-house setup, and every question has its own short timer, the same for every candidate. These measures help keep the focus on the practical knowledge each test is designed to assess.
