What is inside
The iOS Interview Blueprint in its own order: what each part teaches, so you can see whether it covers the round you have next.
- 01
Part 1: Building strong foundations
Junior and mid-level iOS: Swift, UIKit, networking, lifecycle, and the jump to production-grade reasoning.
- 02
Part 2: The senior leap
Senior iOS questions, then a chapter on moving past senior and what changes in scope.
- 03
Part 3: Technical leadership
Tech lead and mobile architect loops: owning direction, architecture decisions and their cost.
- 04
Part 4: The leadership interview
Engineering manager loops, plus delivery on mobile: release timing, Apple's calendar and feature flags.
- 05
Part 5: The hiring loop in practice
Live coding, take-homes and how the modern loop is run.
Is it the right book for you?
Who gets the most from it, and when a different book is the better use of your time. The last list is as important as the first.
Use it when
- You need full coverage of an iOS loop, not one round.
- You can give correct answers but keep getting leveled below where you expect.
- You are moving into a tech lead, architect or manager loop and need the questions for that level.
- You want to see how the same question is answered at baseline, senior and staff depth.
- You have more than a few days before the interview.
Skip it when
- Your interview is 24 to 72 hours away and you need triage first.
- Your main problem is performing while sharing your screen.
- You want job search help such as resume or negotiation; that lives in The iOS Engineer Playbook.
- You are not interviewing for iOS.
By level
- Junior
- Swift fundamentals and UIKit basics with the answer interviewers treat as baseline.
- Mid
- The move from textbook answers to decision rules with trade-offs.
- Senior
- Architecture, concurrency and system design answers with a clear recommendation.
- Lead
- Tech lead questions on ownership, direction and team scope.
- Staff
- The staff+ tier on each question: effect on architecture, migration, reliability and cost.
- Architect
- A dedicated mobile architect chapter.
- Manager
- Engineering manager loops, plus project and delivery management for mobile teams.
What a page looks like
Each question gets three answers: what most candidates say, what a senior candidate says, and what a staff+ candidate says. Red flags and common follow-ups come next, so you can cover the answer and test yourself aloud.

What readers wrote
★★★★★
Thanks so much for this book. The senior interview process for iOS is so intense right now. This context is a natural companion to the daily practice required even for engineers that have been doing this for a long time.
★★★★★
very good for interview preparation, from junior to lead, recomended
★★★★★
I used to fail technical interviews constantly, despite watching countless online courses. Then I found Mr. Mike's book on Linkedin, and it made all the difference. His excellent plan worked for me, leading to my first job contract today! After six months of searching and over ten failed interviews, this book was incredibly helpful. I wholeheartedly recommend this second edition to anyone struggling with technical interviews, it's easy to follow and the best resource out there.
★★★★★
This book is exactly what I was looking for.The sections on modularization, Swift internals, architecture trade-offs and system design felt much closer to real senior-level interviews than anything else I've read. Most interview resources focus on the right answer, while this one helped me understand the reasoning and depth behind it
★★★★★
thank you for putting this together ^_^, I enjoyed reading it and took away several practical insights. Every explanation of different answer levels helped me understand the gap between a correct answer and a strong senior-level answer. This book changed the way I approach interview preparation and helped me focus on demonstrating senior-level thinking, not just giving correct answers ❤❤❤.
★★★★★
Thank you for the quick release of Version 2. The updates make it even better, and it's clear a lot of thought went into improving the content and overall experience.
★★★★★
I love this book. It's become my go-to starting point whenever I'm preparing for iOS interviews. Clear, practical, and packed with valuable insights.
