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 2: What Interviews at Big Companies Look Like

Interviews at big companies are relatively long processes with progressively increasing complexity of technical questions and coding challenges (such an interview process can take a month or even more). Most companies prefer one or more technical phone screens, on-site technical challenges, and in-person interviews before making an offer. Commonly, one of these interviews will be non-technical (known as a lunch interview).

Let's get an overview of how interviews are conducted in several leading IT companies. Generally speaking, all these companies are looking for smart, passionate, and excellent coders.

We will talk about how interviews are conducted in the following companies:

  • Google
  • Amazon
  • Microsoft
  • Facebook
  • Crossover
