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 5: How to Approach a Coding Challenge

This chapter covers technical quizzes and coding challenges, which are commonly used in technical interviews.

The coding challenge is the most important part of an interview. This part can consist of a single session or multiple sessions. Some companies prefer to split the technical interview into two parts: the first part consists of a technical quiz, while the second part consists of one or more coding challenges. In this chapter, we'll tackle these two topics in detail:

  • Technical quiz
  • Coding challenge

By the end of this chapter, you should be able to sketch a plan of your own to approach the technical interview. You'll know how to deal with the key moments during the interview, what the interviewer is expecting to see and hear from you, and how to deal with blocking moments when you don't have a clue about the answer/solution.
