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.

Failure is an option

In movies, we often hear the expression “failure is not an option.” But those are just movies! An interview always ends with an offer or a rejection, and so failure is an option. It is our task to mitigate failures.

Handling failures is not easy, especially when they come one after the other. Each of us reacts to failure in a different and human way. From feeling disappointed and resigned to having a nervous reaction or saying things that you’ll later be sorry about, these all are normal human reactions. However, it is important that you control these reactions and act professionally. This means applying a set of steps that will mitigate failures in the near future. To begin with, it is important to understand why you have been rejected.
