The same answer system, written separately for each platform. Short answers, senior depth, interviewer pushes, traps, recovery lines, and live responses for the loop you actually face.

Definitions get you into the conversation. Follow-ups, trade-offs, and recovery lines decide whether you sound mid-level, senior, or staff. The method is shared. The technical answers are not.
Two platforms, one interview apparatus. These are real pages from both editions.
Every high-priority card gives you the clean answer, the trap, the interviewer push, and the recovery line when your first answer was incomplete.
The Android edition is written around Kotlin, coroutines, Flow, Compose, process death, background limits, offline data, performance, security, and platform leadership. It is not iOS material with renamed APIs.
Senior loops are rarely lost on the first definition. They are lost when the interviewer adds pressure.
In both editions, the highest-priority questions include the weak answer, likely interviewer push, recovery line, and what earns the point.
Know what to read when your loop is tomorrow, tonight, or in thirty minutes.
Swift and SwiftUI in the iOS edition. Kotlin, Compose, runtime behavior, and Android constraints in the Android edition.
Current language, concurrency, UI, architecture, performance, security, system design, and leadership coverage for each platform.
Technical screens, UI and performance pressure, system design, behavioral rounds, incidents, and senior-loop recovery.
Use the scorecard to focus the next hour. Use the final 30-minute review the morning of the interview.
“A professionally written and genuinely useful book. It’s not just something to pick up when you need to quickly prepare for a technical interview — it’s a great resource to revisit from time to time to refresh your knowledge and reinforce key concepts. Clear, practical, and worth keeping within reach. Highly recommended.”
“I came to this book after reading iOS Blueprint and following Mike's advice. Honestly, this book helped me a lot. I had an interview this Monday and only had the weekend to refresh my knowledge. The technical round went well, and I was able to answer almost all of the questions confidently. The only area where I got stuck was explaining Sendable, which showed me where I still need more practice. The next book I'll probably buy is Share Your Screen, especially for the live coding preparation. Mike's approach is very clear, detailed, and easy to follow. The explanations focus on helping you truly understand the concepts rather than just memorizing answers. Thanks a lot for creating these resources, they were genuinely helpful during my interview preparation 👌”
Elena A.“Wow. Just wow. Mike recommended this book during my CV audit, and I grabbed it as part of the deal. Best decision. I've been doing Android for 6 years, and this book made me feel like I was discovering Android again. So many interesting questions and topics that made me stop and think. Highly recommended.”
Emilio Dasna“As mobile developer, I can honestly say this is the best Android book I've ever had!!! The content is excellent, the design is beautiful, and it's been incredibly useful. Huge thanks to Mike for putting together such an awesome resource!!”
Ivan GerasimovReviews shared by readers of the iOS and Android editions.
Over fifteen years, I have built mobile software, worked across iOS and Android systems, and conducted more than 500 technical interviews from the hiring side. I wrote these books for engineers who can build, but need to make their judgment visible under pressure.
Each edition is a separate, platform-native book. Choose the one that matches your loop, or read both samples before deciding.

Yes. The book is specifically structured for limited time. Start with the 2-hour crash path, the 10 answers you must not get wrong, and the simulation closest to your hardest round.
No. Both editions assume you already build production apps on the platform you choose. They are interview answer books, not beginner Swift or Kotlin courses.
No. Choose iOS for a Swift and Apple-platform loop. Choose Android for a Kotlin and Android-platform loop. The interview method is shared, but the technical material is written separately.
PDF and EPUB, with answer cards, code where it clarifies the mechanism, simulations, scorecards, and focused review paths.
Yes. Both are August 2026 editions. Version-sensitive platform material is dated where it matters.
No. Both editions cover the recurring senior interview surface, with guidance for startups, fintech, large product companies, and staff or lead loops.
No. It is interview preparation, not a guarantee of employment. Its job is to sharpen answers, reduce overclaiming, and make follow-ups feel familiar.
Choose the platform in your calendar. Learn the lines, traps, pushes, and recoveries before the interviewer asks.
