What to expect

What is the mobile engineering career?

The Mobile Engineering Career is a free weekly newsletter by Mike Salari for iOS, Android and cross-platform engineers. Each edition examines one practical career or engineering decision: improving recruiter visibility, preparing for senior interviews, explaining architectural tradeoffs, designing reliable mobile systems or growing into staff-level scope. The guidance comes from more than 15 years of production engineering and more than 500 technical interviews, so the focus stays on decisions engineers can apply rather than generic career advice. Readers receive one useful idea, one concrete example and one action worth taking. Editions are written for mid-level, senior, lead, staff and architect engineers who want stronger technical judgment and clearer career positioning. You can review the recent essays, explore the mobile engineering books, or find the right career path before subscribing.

Reader reviews

What changed for engineers who used the work.

Notes from readers on what changed in their interviews, technical judgment and careers.

  • “The interview doesn't start when they ask the question. It starts when they challenge your answer. I kept preparing definitions; interviewers kept asking about trade-offs and failure modes. For the first time in years, I walked in prepared for the conversation, not just the questions.”

  • “I've bought many iOS interview books, but they're all far behind this one ☝️. What I love most is that Mike shares his real experience instead of just listing questions and answers. It's practical, easy to follow, and feels like advice from someone who's actually been through these interviews. I'm still preparing for my interviews, but this book has already changed the way I think about live coding sessions. I've always struggled with explaining my thought process while coding 😭, and this book really opened my eyes to how to approach problems, communicate my reasoning clearly, and avoid turning the session into complete chaos ❤️. Amazing resource! I highly recommend it!!!”

  • “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.”

  • “Usually I don't write reviews but this one really helped me. I used this book and improved my resume and LinkedIn. My visibility score went from 53 to 96 from 100 and I started getting replies and interview invites. I know how to approach recruiters. The idea of signal vs skill made a lot of sense to me. It showed me that I was not being seen clearly, even if I had the skills. The book helped me fix how I present my work in a simple and practical way. After using it, I finally started getting more chances for interviews.”

  • “This book was the gap I didn't even know I had, and is the reason I came back and bought Mike's other books. No motivational nonsense, just practical insights that made a lot of things click for me. A great read. Recommended.”

  • “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.”
