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.

Coding challenge

The coding challenge is the climax of any technical interview. This is the moment where you can show all your coding skills. It's time to demonstrate that you can do this job. Having working and clean code can help you make a great impression. A great impression may fill in the gaps that you left open during any other stage of the interview.

The coding challenge is a double-edged sword that may radically change the final result of the interview. One edge can cut you off from the scheme, while the other edge can bring you an offer in spite of other shortcomings.

However, the problems specific to these coding challenges are really hard for a variety of reasons. These will be covered in the next section.

The problems specific to coding challenges are meant to be difficult

Have you ever seen a problem specific to the coding challenge stage and found it weird, silly, or maybe pointless and nothing to do with real problems? If so, then you've seen an...
