Top 8 Books for Programming/Coding Interviews in 2025 - Best of lot

If you are preparing for Programming Job interviews and looking for some of the best books for programming questions, then you have come to the right place. In this article, I am going to share a couple of good books to prepare coding, software design, and data structure algorithm questions, which are essential for any coding interviews. Though a programming interview also explores other areas of software development, like the programming language, you would be mainly used in your project, like, C++ or Java. The database and SQL-based questions, the operating systems, and UNIX-related questions, some of the software design and object-oriented design pattern questions, and much more, but coding-based questions form the core of programming interviews.

This article solely contains books for coding interviews, but if you are interested in finding good books on other topics, like concurrent programming or Java and other topics, then just look at those links and some more I have shared at the end of this article.

8 Best Books for Programming and Coding Interviews in 2025

This is the second article in the series of must-read books for preparing programming job interviews. In the first article, I have shared books, especially for Java interviews, but after receiving lots of good feedback and request about general programming interview books, I decided to write this article.

I have also not included 10, 15, or 20 books on this list as it would be challenging to consult or refer to too many books. Instead, I always like to have a core group of 3 to 4 best books on a topic; hence, I am only sharing 5 books on Programming/Coding interviews.

1. Cracking the Coding Interview by Gayle Mcdowell

This is your general-purpose coding interview book. Gayle Laakmann McDowell has shared his insights on programming interviews and what tech companies like Google, Amazon, Microsoft, Facebook, Twitter, or Apple look at the candidate when they hire Programmers.

These books give essential basic knowledge by covering all crucial topics of programming interviews, like Data structure, algorithms, SQL, Java, Networking, Database, Operating System, and general guide of how to prepare code interviews.

This book is also a massive collection of common programming questions, which is the most important reason I recommend it.  

Also, good knowledge of computer fundamentals like Data Structure and Algorithms are required to answer these questions, If you need a refresher, you can join Data Structures and Algorithms: Deep Dive Using Java course on Udemy, one of the best course on algorithms.

2. Coding Interview Patterns: Nail Your Next Coding Interview

This is the newest book in this article, which I have added, I read this book during holiday period and really loved it. This book is created by Alex Xu, creator of ByteByteGo and author of famous System Design Interview — Insider guide in collaboration with Shaun Gunawardane.

This book will teach you coding patterns like two pointers, sliding window, fast and slow pointer which you can use to solve 100s of Leetcode problems.

While the idea of coding interview pattern is not new and I already know them having gone through courses like Grokking the Coding Patterns from DesignGurus.io, this book bring them together with more real world examples then you will find elsewhere.

There are 101 real coding interview problems with detailed solutions and most importantly 1000+ diagrams which makes learning really easy. Just because of those diagrams value of the book increased multi-fold.

In short, “Coding Interview Patterns,” is a great book to start your coding interview pattern and master key patterns needed to ace your next coding interview.

3. System Design Interview – An insider's guide By Alex Xu (Part 1 and 2)

System design is an integral part of coding interviews not hence I have included a System design course in this list of best books for coding interviews. As the title suggests, this is the perfect book for everyone who is preparing for a system interview. 

Trust me, this book is the finest on the internet right now. This book is created by Alex Xu who has gone through the same process.

You will get access to a number of drawings and diagrams that will assist you in gaining an understanding of the real system. You will be able to understand what the recruiters are looking for in your answers to questions.

Alex also have a companion System design course on ByteByteGo, where you will not only find all the content of this book and the second part of System Design Interview Book by Alex Wu but also new content, deep dive into popular system questions like how to design YouTube and WhatsApp as well as proven System design framework to solve Software design problem.


In short, if you read this book, you will be able to breeze through your next system design interview. This is also one of the most recommend System design books on Reddit, Quora, Hacker News, Twitter, and other online platforms and its obvious from the number of reviews this book have on Amazon.

4. Hacking the System Design Interview: Real Big Tech Interview Questions and In-depth Solutions

If you need a choice on System design book for coding interviews then this is another book you can read to prepare for FAANG System Design interview. This book not just cover essential System design concepts which every software architect should know but also cover many popular System design questions and coding problems. 

Created by Stanley Chiang, a Google Software Engineer,  this is also one of the best selling book on System design on Amazon.  The best thing about this book is that it walk you through key components which are used to build any system like below:

• Web server
• API gateway
• Load balancer
• Distributed cache
• Asynchronous queue
• Object storage
• CDN
• Fan-out service
• Unique ID generator

This book also includes real interview questions based on hundreds of interviews conducted at big tech companies like Google and Meta, and their detailed solutions. I highly recommend this book to anyone preparing for technical interviews. You can also combine this with the Algomonster or Exponent System design course for better preparation. 

5. Programming Pearls 

This is one of the best books to prepare for coding interviews. The Programming Pearls (2nd Edition) by Jon Bentley focuses on problem-solving, algorithm design, correctness, and performance. The book is old but still worth reading, and it will prepare you well for any type of programming interview.

Some of the questions discussed in this book are simply excellent resources for programming interviews. Don't believe you can decide yourself:

Find all sets of anagrams in the given dictionary.

How to sort 10 million unique non-negative integers, all of which are less than 107 in 1.25M memory?

The question doesn't end here; you have follow-ups like, What if we have only 1M (or less) memory available? What if our integers are not unique, but the number of occurrences of each value is limited?

One more similar questions are:

You have a file with 4 billion 32-bit integers. Find an integer that is not in the file.
With follow-ups like How would you do it if you have an ample amount of RAM? What about the case when you have only a few hundred bytes of RAM, but you are allowed to write temporary files?

This book also has a sequel called More Programming Pearls: Confessions of a Coder, but that's not really about programming interviews or algorithm design, nevertheless a good read for any programmer.

6. Elements of Programming Interviews 

This is one of the excellent books on Programming interviews by Adnan Aziz, Tsung-Hsien Lee, Amit Prakash, who have already authored a couple of books like Algorithm for Interviews, which is aimed to prepare programmers for the most robust programming job interviews with the likes of Apple, Uber, Google, Microsoft, and Amazon.

In short, this is one of the best books to prepare for onsite, face-to-face coding interviews, which might require you to code on the whiteboard. It can also be used as a companion to The Coding Interview Bootcamp: Algorithms + Data Structures course, which contains basic questions more suitable for the face-to-face round of interviews.

7. The Algorithm Design Manual

This is another excellent book to prepare the algorithm design. The Algorithm design manual is written by Steven S. Skiena and also one of the famous algorithms design books too. The only problem is it's hard to read and follow.

If you are like many programmers who find it hard to read books with a lot of theory, then I recommend starting with interview questions and refer to this book when encountering algorithmic concepts. This way, you won't be bored by just reading the theory, and you will also learn the key algorithms.

Though, if you have forgotten fundamental data structure and algorithms which were taught to us in computer science classes, then I strongly suggest you first go to a revision course like  Algorithms and Data Structures - Part 1 and 2 courses on Pluralsight to quickly get up-to-speed. Otherwise, you will have to do a lot of back-and-forth while solving problems from this book.

8. Programming Interviews Exposed

This is the book I first read on the topic of a software engineer or IT interview. It's so good that I can't refrain from recommending this one, the only problem is it's necessary for experienced programmers, but if you want to read your first programming interview book, this should be the one.

It explains in detail how to solve a problem with the pros and cons of different approaches and also covers essential topics for Programming job interviews, like puzzles, string, array, coding, algorithms, binary trees, networking, computer science, etc.

I also recommend you to join Grokking the Coding Interview: Patterns for Coding Questions, a text-based interactive course to learn coding interview patterns like sliding window, fast and slow pointers, merge interval, etc, which can be used to solve 100+ Leetcode problems.

 Knowing those coding patterns not only helps you in coding interviews but also makes you a better programmer. 

And, if you find Educative platform and their Grokking courses like this one and Grokking the System Design Interview, or Grokking the Object-Oriented Programming interview then consider getting Educative Subscription which provides access to their 100+ courses in just $14.9 per month. It's very cost-effective and great for preparing for coding interviews. 

That's all in this list of top 8 books for Coding or Programming interviews. All the papers I have mentioned here are the best of the best, and you can further shortlist depending upon your goals and the companies you are going to interviews with.

For example, if you are targeting Google, then Elements of Programming Interviews and Algorithmic design manual is a must-read, but for most of the programming job interviews, Cracking the Coding interview book will do the job as it covers most popular questions.
