This is the book IвЂ™d give a friend whoвЂ™s looking to prepare for technical interviewsвЂЉ-вЂЉaside from my best-selling interviewing course (Acing The Tech Interview), which prepares any candidate for the entire interview experience from resume preparation, behavioral questions to how to solve coding problems creatively. In short, EPI is the notebook I wished I had when I was preparing for technical interviews. It takes that same approach in explaining almost all the questions, so everyone can understand how to get from a rough solution to an optimized one.ДЇor someone whoвЂ™s rusty and looking to start preparing for interviews, EPI does a great jobвЂЉ-вЂЉevery chapter starts off with a summary of the data structure or algorithm that you will learn, why the data structure is special, what are the strengths/weaknesses of said data structure and what you need to take note of. The book then points out that the additional space is not required, and suggests that detecting cycles in a linked list can be done without additional space by manipulating the pointers instead.

This does the job, albeit it takes additional space (so-called O(N) space complexity and O(N) time complexity). The first approach: use a hash map to store every node you traverse, and then check against the hash map to see if youвЂ™ve seen it. With each iteration, the authors point out where the limitations are and how you can solve them with incremental optimizations.ДЇor example, EPI explains how to detect a cycle in a linked list. The authors then provide concrete examples of how you can improve on the brute force approach. The answers often take a brute force/simplistic approach to the problems. What I really enjoy is that the answers are very, very well constructed. Those are some of the top-level points I enjoyed about the book.

covers relevant technical topics you might get asked in a coding interview, like what is TCP/IP, how the Internet works, and how to capture relationships between different entities in schema design.covers in detail every single data structure you need, algorithms you should know, and techniques you should know in a simple, understandable format.has a great cheatsheet (Chapter 4) that summarizes all the techniques and data structures youвЂ™d need.Suitable for people who want to use the language of their choice comes in 3 different versions: Java, Python and C++.has many questions (300+) with detailed answers, compared to another popular book (Cracking The Coding Interview) that only has 170+.In short: EPI is a highly technical book that is well-suited for anyone looking to prepare for technical coding questions that revolve around data structures and algorithms. The book also offers concrete tips and tricks for solving specific types of coding problems, and includes a cheatsheet to help ace technical questions. The types of technical coding questions vary widely from string manipulation to graph traversals. The book itself is highly technical in nature and deep dives into fundamental computer science. The authors have very strong technical backgrounds, and this is evidenced by the technical focus in the contents of the book.

If youвЂ™re looking for a position as a software engineer, this book will have something for you.Д®PI was written by 3 folks whoвЂ™ve worked across some of the best-known tech companies in the world, the likes of Facebook, Google, Uber, and Microsoft. Elements of Programming Interviews What is this book about?Д®PI is a book that focuses on preparing for technical software engineering interview questions that are commonly asked at tech companies. In todayвЂ™s book review, I go over in detail the good and the bad of one of the top-selling books on Amazon for technical coding interviews: Elements of Programming Interviews (a.k.a EPI, and itвЂ™ll be referred to as such in the rest of this article). If youвЂ™re looking for a book that will teach you how to solve any coding question, guides you on how to design something like Instagram that scales to a billion users, and makes your sandwich while youвЂ™re at it, then this book definitely isnвЂ™t it.Д«ut for polishing your technical chops and making sure youвЂ™re well prepared to face the programming challenges in an interview, this book comes darn close to it. It can sometimes be a daunting task to navigate all the technical coding preparation resources available online, and one might ask: is there a single book/resource that best prepares for technical coding interviews?Д«est, is relative of course in this case. Technical coding interviews are notoriously difficultвЂЉ-вЂЉalmost borderline quiz-like for those unprepared. Is this the best book for technical interviews?
