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 is your experience?

Most probably, after the formal introduction, you'll be asked about your experience. If you don't have an answer prepared for this question, then you are in trouble. Let's highlight several important aspects meant to help you to prepare an appropriate answer:

  • Don't detail your experience as a boring list of chronological facts: Choose the most representative projects and achievements and talk about them with enthusiasm. Talk about your work with enthusiasm (but don't look desperate and don't exaggerate), and place your achievements in the context of the team/project. For example, avoid saying,... and I did this and that on my own! It is better to say,... and I helped my team by doing this and that. Don't say,...I was the only one capable of doing that. Prefer saying...I was nominated by the team to accomplish this delicate task. If you are in your first job, then talk about your school projects (think of your colleagues...
