You have a coding interview in six weeks and a shelf of books that all promise to get you through it. Most of them overlap, two of the most popular are a decade old, and one bestseller now has an official sequel that most lists still miss.
We picked eight books that each cover a different part of the loop: problem patterns, a full problem bank, fundamentals, behavioural questions and the object-oriented design round. Every edition, price and Amazon listing was checked on October 20, 2026, including who actually sells and ships each copy. System design has its own list, so this one leaves it to our system design book guide.

Prices ran from about $26 to $49 on October 20, and book prices change weekly, so check the live price before you order. Page counts are the print editions the links point to. Do you need all eight? No. Step 6 at the end turns them into a short reading plan for the time you have.
Step 1: Start with the book that covers the whole loop
If you buy one book, buy the one written for how interviews run now. It covers four parts of the loop in one plan:
- Problem patterns and practice problems.
- Behavioural questions.
- Referrals and offer timing.
- Salary negotiation.
Beyond Cracking the Coding Interview
Gayle Laakmann McDowell wrote this with Mike Mroczka, Aline Lerner and Nil Mamano as the official sequel to Cracking the Coding Interview, not as a seventh edition. The publisher says it adds 13 technical topics, such as sliding windows, prefix sums and topological sort, and over 150 new problems. It also has chapters on referrals, timing offers, salary negotiation and behavioural interviews, built on data from interviewing.io.
The solutions in the book are Python, with Java, JavaScript and C++ versions online. Two limits matter. It has no system design at all, by the authors’ own choice, and at 644 pages it is a lot to get through in a short prep window. It also appears in our programming book list, so skip ahead if you own it already.
Step 2: Learn the patterns, then drill a problem bank
Once you know the shape of the loop, you need two things: a way to recognise which technique a problem wants, and enough problems to practise it on. These three books split that work, and you only need one of the problem banks:
- Patterns first: Coding Interview Patterns.
- Classic problem bank: Cracking the Coding Interview, 6th edition.
- Densest problem bank: Elements of Programming Interviews.
Coding Interview Patterns
Alex Xu and Shaun Gunawardane organise 101 problems into 19 pattern chapters, from two pointers and sliding windows to tries, backtracking and dynamic programming. The idea is that you learn to spot the signal in a problem, such as a sorted array and a pair of values, and reach for the matching technique. It has over 1,000 diagrams, in the same visual style as the system design books Xu wrote.
The solutions in the book are Python, and the official repo adds folders for C++, Java, Go, Kotlin, Rust, Swift, TypeScript and C#. It covers nothing beyond the coding round: no behavioural questions and no job-search advice. Many of the problems are familiar from free lists, so you are paying for the explanations and diagrams.
Cracking the Coding Interview, 6th Edition
The 6th edition from 2015 is the latest numbered edition on its own site, and McDowell and her co-authors released the sequel instead of a 7th. It has 189 questions with hints and full solutions. The solutions are almost all Java. It is the most-reviewed book on this list, with 9,788 Amazon ratings on October 20, and the cheapest pick at about $26.
Read it as a second problem bank, not your main plan. It predates the sliding window and prefix sum emphasis that the sequel added, and its hiring advice still talks about Google and Facebook. Amazon showed it in stock on the product page while the Amazon API showed a backorder, so check the listing says In Stock before you order. Buy ISBN-10 0984782850 (ISBN-13 978-0984782857, 687 pages), which our link uses. The product page also shows ISBN-10 0984782869, but that number leads to a different 551-page listing, so do not search by it.
Elements of Programming Interviews in Python
Adnan Aziz, Tsung-Hsien Lee and Amit Prakash wrote the densest book here, aimed at the hardest loops, with over 250 problems, 300 tested programs and 150 extra variants. The authors say they wrote the Python code from the ground up, and their free EPI Judge project gives you stub programs and tests for each problem in Python, Java and C++. That makes it the best fit if you like to practise against a test suite on your own machine.
The solutions are terse, and the Python edition dates from 2016. On Amazon US the Python copy came from a third-party seller with Amazon shipping and five left. The authors warn that the latest printing is the one where the seller is Amazon, which may not be the default seller, so check who sells it before you order. The Java edition was sold by Amazon at about $19, which makes it the safer buy if Java works for you. Pick this over Cracking the Coding Interview if you are aiming at the hardest loops and already know the basics well.
Step 3: Rebuild the fundamentals if they are rusty
Pattern books assume you already know big O, hash tables, trees and graphs. If you have not touched them since university, or never studied them, spend the first week or two on one of these before you drill problems.
A Common-Sense Guide to Data Structures and Algorithms, 2nd Edition
Jay Wengrow explains each data structure in plain language, with examples in JavaScript, Python and Ruby. The second edition added chapters on recursion, dynamic programming and using big O in daily work, plus heaps, tries and practice exercises in every chapter. It is the gentlest book here, which suits career switchers and bootcamp graduates.
It is a teaching book, not an interview problem bank, so it has no interview walkthroughs. The print edition is from 2020, and Amazon sold it directly on October 20. If you prefer more illustrations, Grokking Algorithms, 2nd edition, covers similar ground and is already in our programming book list.
The Algorithm Design Manual, 3rd Edition
Steven Skiena splits the book into two halves: how to design algorithms, and a catalogue of problem types with the known approaches for each. Springer says the 3rd edition adds over 100 new problems, including programming challenges from LeetCode and HackerRank, and the exercises also include job interview problems from major software companies. The code is in C, so our C and C++ book list helps if your C is rusty.
At 810 pages it is a textbook, and more theory than a six-week cram needs, so treat it as a reference for graph-heavy or senior loops. On Amazon US the hardcover came from a third-party seller with Amazon shipping, and it was cheaper than the paperback that day. It is also in our programming book list.
Step 4: Prepare the behavioural round
At senior levels, the behavioural round can matter more for levelling than the coding rounds, as the book below argues, yet it is the round many people prepare for last. One book is enough here, as long as you write your own stories while you read it. For each story, note down:
- The situation and your role in it.
- What you did, in your own words.
- The result, with a number if you have one.
Technical Behavioral Interview: An Insider’s Guide
Steve Huynh joined Amazon as a software engineer nearly twenty years ago, conducted close to a thousand interviews there and became a Bar Raiser, and the book reads like it. It has over 130 interview questions and 72 example stories from entry level to principal, grouped into competencies such as taking initiative, delivery, conflict and strategic leadership. It came out in March 2026, so it is the newest book on this list.
The lens is the Amazon one, which suits leadership-principle loops and anyone worried about being levelled down. The same text runs as a ByteByteGo course, so check whether you already have access before you buy print. It had 45 ratings on October 20, the second-fewest here after Object Oriented Design Interview with 34.
Step 5: Cover the object-oriented design round
Some companies run a low-level design round, where you model a parking lot or a vending machine in classes, instead of or as well as distributed system design. Amazon, Bloomberg and Uber are the examples the authors give.
Object Oriented Design Interview: An Insider’s Guide
Desmond Zhou, Fawaz Bokhari and Alex Xu give a four-step framework and work through 11 problems in full, including a parking lot, an elevator, an ATM, a movie ticket system and a restaurant. The code is Java, and the ByteByteGo course page carries the same material online.
Eleven problems is a small set, and it was full price at about $45 on October 20. For distributed system design, which this book does not cover, use our system design book list instead.
Step 6: Plan the weeks before your interview
How much you read depends on how long you have. The table below is the plan we would follow, and it assumes you code in a mainstream language already:
| Time until the interview | Read | Skip |
|---|---|---|
| Two weeks | Coding Interview Patterns, plus your stories from Technical Behavioral Interview | Everything else |
| Six weeks | Beyond Cracking the Coding Interview, skimming Coding Interview Patterns for extra drills | The Algorithm Design Manual |
| Three months, rusty fundamentals | A Common-Sense Guide first, then Beyond Cracking the Coding Interview | Elements of Programming Interviews |
| Hard loop, strong fundamentals | Elements of Programming Interviews, then The Algorithm Design Manual as a reference | A Common-Sense Guide |
| Low-level design round on the schedule | Object Oriented Design Interview alongside your main book | None |
Whatever the plan, solve problems out loud with a timer, because reading a solution is not the same as producing one under pressure. If you write Python or Java for the interview, our Python book list and Java book list cover the language side.
