The Complete Coding Interview Guide in Java

By: Anghel Leonard

Overview of this book

Java is one of the most sought-after programming languages in the job market, but cracking the coding interview in this challenging economy might not be easy. This comprehensive guide will help you to tackle various challenges faced in a coding job interview and avoid common interview mistakes, and will ultimately guide you toward landing your job as a Java developer. This book contains two crucial elements of coding interviews - a brief section that will take you through non-technical interview questions, while the more comprehensive part covers over 200 coding interview problems along with their hands-on solutions. This book will help you to develop skills in data structures and algorithms, which technical interviewers look for in a candidate, by solving various problems based on these topics covering a wide range of concepts such as arrays, strings, maps, linked lists, sorting, and searching. You'll find out how to approach a coding interview problem in a structured way that produces faster results. Toward the final chapters, you'll learn to solve tricky questions about concurrency, functional programming, and system scalability. By the end of this book, you'll have learned how to solve Java coding problems commonly used in interviews, and will have developed the confidence to secure your Java-centric dream job.

What's your working style?

This kind of question should ring a bell to you. Most of the time, this question is specific to companies that have an uncommon working style. For example, they often work overtime or they work on weekends. Maybe they work long shifts or they have metrics or deadlines that are hard to achieve. Or, they put a lot of pressure and responsibilities on this position. Explain to the interviewer your working style and underline indirectly the things that you do not agree with. For example, you could point out that you are not open to doing night shifts by saying, I like to start working in the morning with the most difficult tasks, and in the second part of the day, I will deal with the planning of the next day. Or, you could point out that you are not open to working on weekends by saying, I like to work hard for 40 hours/week from Monday to Friday. I like to spend weekends with my friends.
