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.

Interviews at Amazon

The Amazon interview starts with a technical phone screen conducted by a team from Amazon. If some interviewers are not convinced after this phone screen, then it is possible that they will ask for another one to clarify the issues.

If you pass the technical phone screen(s), then you will be invited to several face-to-face interviews. A team of interviewers from different areas of the business will individually conduct an interview and evaluate your technical skills (including coding). One of them is also known as the bar raiser guy. Commonly, this guy is the most experienced, and his questions and coding challenges will be harder. They will evaluate you against other candidates as well, and they will decide whether to make an offer or not.

The main focus is on Object-Oriented Programming (OOP) and scalability.

If you don't get any feedback after a week, then you should trigger a friendly follow-up e-mail to Amazon contacts. Most probably, they will...
