On working with Mike

2 recommendations written on LinkedIn, counted separately from the 43 product reviews below.

“Mike has a rare ability to spot not just what you're saying, but how you're saying it.

During our conversations, he helped me realize that I was explaining my career instead of demonstrating my value. It was a subtle shift, but an important one.

What I appreciated most was that his advice was practical, specific, and always backed by clear reasoning. He doesn't give scripted answers - he teaches you how to think about interviews from the interviewer's perspective.

I came away with a much clearer understanding of how to present my experience with confidence and structure. I'm grateful for the conversations, and I'd happily recommend Mike to anyone preparing for software engineering interviews.”

“Interview prep right now in native mobile is daunting to say the least. Mike has helped me personally work through all the noise and pin point what to focus on. He's a window to the POV of the other side of the table. It is unusually tough out there, but I appreciate the guidance that has made the daily prep work more productive.”

Engineer Career Rebuild

  • “I spent the last 7 years not thinking about my CV or LinkedIn for that matter. It was eye opening to find out how much those 2 things matter and how important it is that their respective messaging is aligned. The engineering rebuild helped me with a core issue. Simply facing the truth of how to present myself. Every detail matters and the rebuild was critical to putting the whole package together. Details like what to say or not say in a cover letter was particularly useful. The rebuild comes with an almost shocking level of content, but it is all personal/relevant. It really is a window into the other side of the table and almost fascinating to see all the details that should be considered. The voice guide is a useful call out. Mentally super helpful to break down each member of the interview loop to target your voice towards each. Also on flip side it was helpful to think about presenting a consistent message to each stage of the loop. This rebuild has helped me get to the table. There is so much more work to do, but this was critical to establishing a foundation to work from. Josh”

So far, I’ve found it really useful and I feel like I have a much better idea of what I should be doing and where to focus my efforts. I haven’t found a job yet, but I understand the process a lot better now and feel more confident about the direction I’m taking. Overall, I’m happy with it and would definitely recommend it to anyone who’s looking for some guidance.”

  • “After 5 months of searching and getting rejection after rejection, I was honestly tired. I have 6 years of Android experience, but my CV, LinkedIn, and the way I was presenting myself were just not working. I found Mike through a recommendation, followed his advice, and started getting recruiter responses in about 1.5 weeks. Soon after, I signed with a great company as a contractor. The craziest part is looking at my old CV now. I'm honestly embarrassed by it. The experience was there, but the presentation was completely wrong. I also bought Mike's Android interview book. Great value and great content. I can't really compare them to anything else I've seen on the market. No magic, no BS. Just a strategy that worked.”

Engineer Career Reset

  • “I thought I needed to prepare harder. Turned out my formal title was one level below what I had on my CV, and I had no idea. Everyone internally called me Senior. HR said otherwise. Found before an offer rather than after, which is the difference between a correction and a withdrawn one. The part I did not expect was the sentence a panel would say about me in a debrief. It was not the one I had been trying to make them say. I was leading with the company name. The actual asset was buried in my third bullet. Not everything landed, and it is written, so if you want someone to talk it through, this is not that.”

The Silent Rejection

2 reviews, average 5.0 out of 5

See the book
  • “Short, but don't let the size fool you. I first read this book when it was called "The Engineer Visibility" and I think the new title matches its purpose much better. As engineers, we are always focused on the skills we need to improve, but we often forget that there is another layer before those skills are evaluated, and maybe not forgetting it, we just don't know it exist. The first person looking at your profile or resume usually won't have the time or even the technical background to evaluate your skills. Mike explains this really well. More than just quick theory, this is something you can apply immediately. I unfortunately didn't do that right away and that was on me. So my recommendation is to sit down for 30-40 minutes and read it in one go. It's simple, practical and easy to understand. By the end you will have a clear path to improve that layer we ignore (or do not know it exists, at least I never considered it). As a close this book will help you to know how visible and understandable our value is before anyone gets the change to evaluate our actual skills. And a plus! if you have been actively applied recently without answer, also to know why you might being rejected and another PLUS PLUS! to show what you can actually do to improve that.”

  • “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.”

Share Your Screen

  • “If you have an upcoming technical interview and even if you think you are prepared you should buy Share Your Screen. The book is well strucutured, with real life examples of what sets you as a senior developer, and it also has numerous examples of mock interviews with practice exerises that will help you better understand what the interviewer will want from you. It helped me during my interview processes but also how I structure my code better and do better development.”

    Aurelian GavrilaSenior iOS DeveloperGumroad and LinkedIn feedback
  • “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!!!”

    Ivan G.Gumroad verified purchase
  • “Most iOS interview books stop at 'here's the answer.' This one shows you the entire conversation: the interviewer's follow-ups, where candidates stall, and what a strong recovery looks like. I ran two of the annotated mocks with a colleague before my onsite, and I got the offer.”

    Daniel K.Early reader, Gumroad verified
  • “I'm a solid engineer, but I used to be terrible at live coding, dealing with screen-sharing anxiety and blanking on APIs I use daily. The test-first opening strategy and the mock transcripts gave me a reliable script for the first five minutes, and momentum carried me through the rest. I signed an offer last week with a 24% compensation bump.”

Ticket Taker, Outcome Owner

2 reviews, average 5.0 out of 5

See the book
  • “Wow, this resource description was really good and engaging. I was expecting something more specific to the work you do on the ticket, but it actually takes you far beyond that. The ticket is certainly the starting point, but this resource explains the bigger picture, and because of that, it was completely worth it for me. Simply put, I was expecting it to focus only on the ticket workflow, so I was completely wrong about where the developer’s system was designed to build trust. I don’t want to spoil anything, but I can say this: if you think the outcome depends only on how quickly you work through your ticket, then please get your copy. You’ll thank Mike for every topic he covers.”

  • “I'm a pretty shy person 🧍, so I didn't expect to enjoy this book as much as I did. It teaches you how to be proactive at work in a practical way.. No corporate buzzwords, just things you can actually do. It made me realize how many opportunities I was missing simply by staying quiet. Loved 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.”

    Vivek K.Gumroad verified purchase
  • “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”

    Alexander JohanssonGumroad verified purchase
  • “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 ❤❤❤.”

  • “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.”

    Olha B.Gumroad verified purchase
  • “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 👌”

  • “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.”

    MarkEarly reader, Gumroad verified
  • “The cards are about a page each but cover exactly what interviewers ask. I read the token-refresh section the night before and got almost that exact discussion in the loop.”

  • “Instead of saying 'I'd use MVVM,' I started explaining why I'd choose it and when I wouldn't. That changed the entire conversation in my interviews.”

I am a shy person and I had many problems with recruiters, job interviews, and the whole process. This book opened my eyes. It showed me what I was doing wrong and how much impact small changes can make. I never felt so clear, so confident, and so motivated in how I approach job applications. I finally feel like I know what I am doing. Thank you Mike, I emailed you, thank you, I really appreciate this work.”

  • “I honestly thought the Leverage book would be a nice bonus and that the CV audit already covered everything I needed. I was wrong. This is a completely different level. It's not the kind of thing you'll find on Amazon or in a typical career book. It feels like it's built from years of real experience and lessons learned the hard way. The negotiation insights alone are next level. Leverage level 99+. Highly recommended.”

Then I came across one of Mike’s articles on Medium, loved the way he explained things, and decided to take the risk and buy the Complete Bundle. Yes, it’s not cheap, but after going through it, I can honestly say it’s worth every penny. The structure, the narrative, the demo project, the documentation… everything is incredibly well thought out. I absolutely love it. Easily one of the best investments I’ve made in learning SwiftUI!!!!!!!!!”
