Choosing for one loop? Compare the titles by the time you have left: iOS interview books · Android interview books.
iOS
Five iOS interview books, from 24-hour triage to the whole career arc. The iOS Interview Blueprint covers the full loop over weeks; the 24-Hour book is answer cards for a loop that is days away; Share Your Screen is for live coding and code review rounds; SwiftUI Under Load goes deep on SwiftUI state and performance; the iOS Engineer Playbook runs from getting found to the offer. Each page says who should skip it.
Android
Two Android interview books. Senior Signal is the full senior Android loop: Kotlin, coroutines, Flow, Jetpack Compose, architecture, performance, security and system design. The 24-Hour Android Interview Answer Book is 160 answer cards for an interview within a week, with the spoken wording, the push and the recovery line.
Flutter
One Flutter interview book: a question bank of 500 Flutter and Dart interview questions, junior to Staff, across widgets, state, architecture, performance and native integration. There is no interactive Flutter practice yet, so answer each question out loud before reading the answer.
React Native
One React Native interview book: 300 questions, junior to Staff, on hooks, the New Architecture, Hermes, native integration and performance. There is no interactive React Native practice yet; the question bank is the honest place to start.
Cross-platform
Books that are not tied to one platform: the Mobile System Design Blueprint for the design round, Altitude for the step to Staff and architect scope, and Security Is a Feature, a free field guide. They pair with any platform book above.
Staff and leadership
Two books for the step beyond the interview loop. Before the Room is on leading outcomes you have no authority to command: three moves, Surface, Shift and Secure, with 16 artefacts, each with a completed example. Controlled Change is a mobile architecture book for staff engineers and architects: 505 pages on which boundary is worth its cost and how a live system keeps changing.
