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.

Chapter 4: How to Handle Failures

This chapter discusses a delicate aspect of interviews—handling failures. The main purpose of this chapter is to show you how to identify the causes of failure and how to mitigate them in the future.

However, before discussing handling failures, let’s quickly tackle the proper way to accept or decline an offer. At the end of an interview, or at some point during the interview, you may find yourself in a position to accept or decline an offer. This is not about giving a simple and dry yes or no answer.

Our agenda for this chapter includes the following:

  • Accepting or rejecting an offer
  • Considering that failure is an option
  • Understanding that a company can reject you for a lot of reasons
  • Objectively identifying and eliminating the mismatches
  • Not forming an obsession for a company

Let’s get started with the first topic.
