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.

Why are you looking to change jobs?

Of course, if you are at your first job then you will not get such a question (or its sister,How and why did you leave your last job?). But if you had a previous role (or you plan the change your current role), then the interviewer will want to know why you took this decision. The key here is to detail clear and solid arguments without saying anything bad or offensive about your previous company, bosses, coworkers, and so on – follow the principle that if you can't say anything nice about someone, don't say anything at all.

Here are some tips that will help you with this question (pay attention to how this question is interleaved with the previous one – if the working style of this company relates nicely to the style of your current or ex-company, then most likely, the same reasons for leaving that job will apply to avoiding this job as well):

  • Don't cite money as the first argument: Money is often a good reason...
