TL;DR: These are not the same kind of thing. Cracking the Coding Interview (CtCI) is a book that orients you to the whole interview: the process, the behavioral rounds, big-O, and a broad problem sampler organized by data structure. Grokking the Coding Interview is a course whose entire job is to install the pattern-solving skill: 42 patterns taught before the problems, 300+ sequenced problems, six languages, and an in-browser practice environment. If you have never interviewed and want the landscape explained, start with CtCI's front chapters. If your goal is to walk into the room able to recognize and solve the problem in front of you, that is what Grokking is built for. Many people read CtCI once for orientation and do their actual problem prep somewhere pattern-first.
Let me get the obvious thing out of the way: I created Grokking the Coding Interview. So apply the skepticism you would apply to any comparison written by one of the two parties. What I will do is tell you plainly where CtCI is the better choice, tell you who should not buy my course, and keep every claim checkable. The query that probably brought you here deserves a straight answer, not a sales page wearing a comparison's clothes.
What each one actually is
They get compared constantly, but they are different species, and that is the whole story.
Cracking the Coding Interview is a book by Gayle Laakmann McDowell, a genuine classic that introduced a generation of engineers to the interview. Its sixth edition carries 189 problems across roughly 700 pages, plus standout non-coding material: how the process works, how to behave in the room, how to reason about big-O, and how the behavioral rounds are graded. The coding chapters are organized by data structure and topic: arrays and strings, linked lists, stacks and queues, trees and graphs, and so on. Solutions are in Java. There is no practice environment and no video; it is a book, and it reads like one.
Grokking the Coding Interview is a course, not a problem sampler. It teaches 42 coding patterns (32 common + 10 advanced) across 50 chapters and 669 lessons, organized by pattern rather than by data structure. Each chapter introduces a pattern (what it is, the tell that reveals it, its template), then walks through hand-picked problems in increasing difficulty, 300+ problems in total, with full solutions in Python, Java, C++, JavaScript, Go, and C#, and 751 in-browser playgrounds so you run code as you read. It is a one-time purchase (around $79 at the time of writing, or via the Design Gurus all-courses subscription), rated 4.6/5 by roughly 63,000 learners.
That single difference, organized by data structure vs organized by pattern, drives everything below.
The structural difference, in one picture
A table of contents by data structure answers "what is this problem about?" A table of contents by pattern answers "how do I solve the problem in front of me?" In a real interview you are handed an unfamiliar problem and asked the second question, under time pressure. Learning by data structure teaches you the vocabulary; learning by pattern teaches you the move. Both matter, but only one of them is what the interviewer is timing you on. We made the full case for this in Learn the Patterns, Not the Problems.

Where Cracking the Coding Interview is genuinely better
The non-coding chapters. CtCI's material on how the process works, how offers and levels are decided, and how to handle behavioral questions is still excellent, and Grokking simply does not cover that ground. If you have never interviewed at a big company and do not know what the day looks like, those chapters are worth the price on their own.
Orientation for a true beginner. As a warm, thorough first read for someone who is not yet sure what an interview even involves, the book is hard to beat. It assumes little and explains patiently.
It is a book. Some people learn better from a physical book they can annotate away from a screen. That is a real preference, and CtCI serves it. A used copy is cheap.
Where Grokking is genuinely better
It teaches the move, not just the topic. CtCI groups problems by data structure and hands you solutions; you infer the reusable technique yourself. Grokking inverts that: each chapter teaches the pattern first (its tell, its template, its boundaries), then gives you problems ordered to stretch that template one variation at a time. That is the difference between reading 189 solved problems and installing 42 transferable solving methods. You can see the shape of it in our sliding window deep dive.
Coverage that matches interviews as they are now. A fixed edition cannot add the patterns that have come to dominate loops since it was printed, monotonic stack being the most glaring gap, nor address the speed bars and AI-assisted rounds that shape interviews today. Grokking is maintained and expanded; the book is a snapshot.
Six languages and a place to run them. CtCI's solutions are Java only, on the page. If you interview in Python, Go, C#, C++, or JavaScript, Grokking ships full solutions in all six, with 751 playgrounds to execute and modify them as you learn.
Sequencing. The book is a sampler you dip into; the course is ordered so each pattern reuses machinery from the last. That progression is the difference between a reference and a curriculum, and it is why we built Grokking 75 the same way.
See the teaching style for yourself: the free tier of Grokking the Coding Interview includes the introductory lessons, so you can judge the pattern-first approach before spending anything.
The decision, by situation
You have never interviewed and want the whole landscape explained. Start with CtCI's front chapters (process, behavioral, big-O). They are the best orientation in the genre, and Grokking does not try to replace them.
Your fundamentals are shaky (arrays, hash maps, recursion still feel wobbly). Read the early CtCI chapters, or take a fundamentals course like Grokking Data Structures first. A patterns course assumes fundamentals; buying it too early wastes it, and I would rather tell you that than sell it to you twice.
You know the basics and keep failing on unfamiliar problems. This is the pattern-recognition gap, and it is exactly what Grokking is built to close. The book will not fix it, because reading solutions is not the same as learning to generate them.
You interview in anything other than Java. Grokking, for the language coverage alone.
Your interview is soon and you want a short, sharp list. Neither the full book nor the full course finishes in two weeks. Do a focused 75-problem plan; the honest three-way comparison is in Blind 75 vs NeetCode 150 vs Grokking 75.
The combination (very common and genuinely sensible). Read CtCI once for orientation and the behavioral material, then do your problem prep pattern-first. The two barely overlap, so this is not paying twice for the same thing; it is buying two different things.
The takeaway
Cracking the Coding Interview is a great book about interviewing, and its process and behavioral chapters still have no real substitute. Grokking the Coding Interview is a system for learning to solve, pattern-first, sequenced, multi-language, and kept current. They answer different questions, which is why the smartest move is often to use the book for orientation and a pattern course for the skill the interviewer is actually timing. Whichever you choose, finish it.
Ready to close the pattern-recognition gap? Grokking the Coding Interview teaches all 42 patterns (32 common + 10 advanced) across 300+ problems, in six languages, with lifetime access for a one-time $79. Short on time? Grokking 75 distills it into a focused plan.
FAQs
Is Cracking the Coding Interview enough on its own? For understanding the process and behavioral rounds, close to it. For problem-solving, no: 189 problems organized by data structure, Java-only, with no practice environment and no coverage of newer patterns, leaves the pattern-recognition skill under-trained. Pair it with something pattern-first. Our full assessment is in Is Cracking the Coding Interview Still Worth It?.
Is Cracking the Coding Interview a course? No, it is a book by Gayle Laakmann McDowell. People search for "cracking the coding interview course" expecting videos or a platform, but CtCI is print/PDF only, with no interactive practice. If you want a course-style, pattern-first experience, that is what Grokking the Coding Interview provides.
Is this the same Grokking the Coding Interview that was on Educative? Same course lineage, different home. The original authors moved it to designgurus.io, where it is maintained and expanded (now 42 patterns and 300+ problems). designgurus.io is where the original team publishes it.
Which is better for FAANG specifically? Read CtCI's process and behavioral chapters, then build the solving skill pattern-first. FAANG loops draw from the pattern space Grokking teaches, and the newer patterns the book predates (monotonic stack among them) show up in real loops. Add mock practice in the final two weeks regardless.
Can I use both without wasting money? Yes, and it is the setup I would actually recommend: a used copy of CtCI for orientation and behavioral prep, and Grokking for the pattern-solving skill. They cover different ground, so you are not paying twice for the same content.
