What readers wrote
★★★★★
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 👌
