| basic kotlin interview questions: Building Mobile Apps at Scale Gergely Orosz, 2021-04-06 While there is a lot of appreciation for backend and distributed systems challenges, there tends to be less empathy for why mobile development is hard when done at scale. This book collects challenges engineers face when building iOS and Android apps at scale, and common ways to tackle these. By scale, we mean having numbers of users in the millions and being built by large engineering teams. For mobile engineers, this book is a blueprint for modern app engineering approaches. For non-mobile engineers and managers, it is a resource with which to build empathy and appreciation for the complexity of world-class mobile engineering. The book covers iOS and Android mobile app challenges on these dimensions: Challenges due to the unique nature of mobile applications compared to the web, and to the backend. App complexity challenges. How do you deal with increasingly complicated navigation patterns? What about non-deterministic event combinations? How do you localize across several languages, and how do you scale your automated and manual tests? Challenges due to large engineering teams. The larger the mobile team, the more challenging it becomes to ensure a consistent architecture. If your company builds multiple apps, how do you balance not rewriting everything from scratch while moving at a fast pace, over waiting on centralized teams? Cross-platform approaches. The tooling to build mobile apps keeps changing. New languages, frameworks, and approaches that all promise to address the pain points of mobile engineering keep appearing. But which approach should you choose? Flutter, React Native, Cordova? Native apps? Reuse business logic written in Kotlin, C#, C++ or other languages? What engineering approaches do world-class mobile engineering teams choose in non-functional aspects like code quality, compliance, privacy, compliance, or with experimentation, performance, or app size? |

| basic kotlin interview questions: Androids Chet Haase, 2022-07-19 The fascinating inside story of how the Android operating system came to be. In 2004, Android was two people who wanted to build camera software but couldn't get investors interested. Today, Android is a large team at Google, delivering an operating system (including camera software) to over 3 billion devices worldwide. This is the inside story, told by the people who made it happen. Androids: The Team that Built the Android Operating System is a first-hand chronological account of how the startup began, how the team came together, and how they all built an operating system from the kernel level to its applications and everything in between. It describes the tenuous beginnings of this ambitious project as a tiny startup, then as a small acquisition by Google that took on an industry with strong, entrenched competition. Author Chet Haase joined the Android team at Google in May 2010 and later recorded conversations with team members to preserve the early days of Android's history leading to the launch of 1.0. This engaging and accessible book captures the developers' stories in their own voices to answer the question: How did Android succeed? |
| basic kotlin interview questions: How to Get a Job in Web Development RealToughCandy, 2018-07-31 How to Get a Job in Web Development is designed for junior web developers. Whether you’re coming from a coding bootcamp, are completely self-taught, or graduated from college with a tech-related degree, this book is for you. Written by RealToughCandy. In this book, you will learn how to: • Expertly craft the ‘holy clover’ of application materials: your resume, cover letter, GitHub page, and portfolio. • Leverage the power of LinkedIn, Meetups, and social media. • Handle follow-up emails and phone calls. • Prepare for the multiple types of interviews you will encounter, whether via phone, video conference, or in person. • Strategically apply to jobs so you can maximize your salary demands during negotiation. • Efficiently organize and prioritize the jobs you’ve applied to. • Craft results-driven email check-ins with your potential employer. • Reduce your vulnerabilities for discrimination. • And much, much more! No awkward whiteboard interviews. No hour-long explanation of Big O notation. Just practical, actionable steps that will put you far ahead of the pack when it comes to getting a job in web development. Now let's go get that job! Just finished reading your book and all I can say is WOW! Mind you since May of 2016 I have taken about 6 online courses specifically looking for employment and around three of them were specifically for either how to get an IT or Web Developer job. These courses cannot hold a candle to the majority of the information you put in this book! -George M., Web Developer WHY I WROTE THIS BOOK: When I started my web development journey, I was a lost hiker in the digital woods. I knew I wanted to build web apps, but didn’t know what those people called themselves. Were they website builders? Programmers? The term ‘software engineer’ floated around a lot online – was that my aspiration? Since I didn’t know exactly what I was looking for, I spent a lot of time reading and watching materials that were nothing but discouraging: mock Google coding interviews with whiteboards and markers. Lots of articles and videos that name-dropped things like binary trees, Big O notation, and time complexity. Forum post upon forum post that gave away actual coding interview questions from the biggest tech companies in the world like Facebook, Google, and Microsoft. Making things worse, some web developers I had discovered on YouTube were talking about a really good, popular book for coding interviews. I checked it out and once again my stomach sank. “I’m never going to make it in this field,” I said to myself. “I’ve been studying and practicing and building projects for months, and I still have no idea what these people are talking about.” What they didn’t tell me was that the book is geared towards senior software engineers trying to get a job with Amazon and Google. I wanted to quit my coding journey. In fact, I did quit. The difference was, I didn’t stay quit. Something told me to keep pushing forward, keep building projects to put in my portfolio and Github, keep reaching out and trying to find clients who needed websites. I kept pushing until I got a job as a fullstack web developer at a data company. As it turns out, the internet isn’t very generous to our career field. Beginners are especially marginalized. There aren’t any quality one-stop resources for discovering one of the most important questions – if not the most important question – web developers have. “How do I get a job in this field?” I wanted to change the junior web developer tech landscape with this book. My goal is for every junior developer who reads this to find a job. And if you take the recommended actions in this book, you can do it. |
