If you had asked me how I was preparing for coding interviews a year ago, I would have proudly answered, "I'm solving as many LeetCode problems as possible."
At the time, it sounded like the right strategy. Every interview prep guide seemed to recommend solving hundreds of problems, so I assumed success was simply a numbers game.
It wasn't.
The more questions I solved, the more I realized I wasn't actually becoming a better problem solver. I was becoming better at recognizing questions I had already seen. Whenever an interviewer slightly changed a familiar problem or introduced something completely new, I found myself back at square one.
That frustration led me to search for the Best Grokking Coding Interview Patterns Course, hoping there was a better way to prepare than endlessly grinding random problems.
After working through Educative's Grokking the Coding Interview Patterns, I honestly wish I had discovered it much earlier.
This isn't a sponsored review or an attempt to convince everyone to stop using LeetCode. It's simply my experience of switching from memorizing individual questions to learning the patterns behind them.
Why my original interview preparation wasn't working
I wasn't lazy. In fact, I was probably practicing too much.
Every evening I would open LeetCode, pick a random medium problem, spend thirty or forty minutes struggling with it, read the solution, understand it, and then move on to the next one.
The next day I would repeat the same process.
The problem was that every question felt completely unrelated to the previous one.
- Some days I practiced binary trees.
- The next day it was dynamic programming.
- Then graphs.
- Then heaps.
- Then backtracking.
I never felt like I was building momentum because everything seemed disconnected. Eventually I realized I wasn't learning strategies. I was collecting solutions.
Looking for the Best Grokking Coding Interview Patterns Course
Once I started reading recommendations from engineers who had successfully landed offers at large tech companies, one idea kept coming up repeatedly.
Don't memorize problems. Learn patterns.
That sounded much more practical.
Instead of remembering hundreds of individual solutions, experienced engineers talked about recognizing recurring approaches like sliding window, two pointers, binary search, fast and slow pointers, merge intervals, and dynamic programming.
Naturally, I started searching for the Best Grokking Coding Interview Patterns Course, and Educative's Grokking the Coding Interview Patterns kept appearing in discussions and recommendations. The course is built around 28 reusable coding patterns, includes 500+ hands-on challenges, 17 mock interviews, and supports multiple programming languages including Python, Java, JavaScript, Go, C++, and C#.
That sounded much closer to the way I actually wanted to learn.
The biggest difference was the way the course teaches
Most interview resources organize content around data structures. This course organizes everything around thinking patterns.
At first, I didn't appreciate how important that difference would become.
Instead of saying, "Here's another array problem," the course focuses on identifying the strategy hidden inside the question. Once you recognize the pattern, solving unfamiliar problems becomes significantly easier because you're no longer starting from scratch every single time.
That completely changed how I approached coding interviews.
My experience after the first few chapters
The first pattern I worked through was the Two Pointers technique.
I had solved several Two Pointer questions before, but I never realized they all followed the same underlying idea.
Once the course explained the intuition first and then gradually increased the difficulty, something finally clicked.
The same thing happened with Sliding Window.
Then Binary Search.
Then Fast and Slow Pointers.
Instead of adding isolated solutions to my memory, I was building a toolkit that I could reuse across dozens of different interview questions.
That was probably the first time coding interview preparation actually felt enjoyable.
What changed in my preparation
| Before the course | After learning coding patterns |
|---|---|
| Memorized individual problems | Recognized reusable strategies |
| Random LeetCode practice | Structured learning roadmap |
| Often started from scratch | Identified familiar approaches quickly |
| Focused only on solving | Focused on understanding why solutions work |
| Progress felt inconsistent | Improvement became much easier to measure |
Looking back, I think this was the biggest reason my confidence improved. The course gave me a framework instead of another collection of questions.
Why I think this is the Best Grokking Coding Interview Patterns Course
There are plenty of coding interview resources available today.
Some focus on videos.
Others provide enormous problem libraries.
Some simply list hundreds of interview questions without much explanation.
What stood out to me about Educative's course was that it teaches the reasoning behind every pattern before asking you to solve increasingly challenging problems. Every chapter also includes practice questions and AI-powered mock interviews that encourage you to apply what you've just learned instead of immediately moving on to another topic.
That progression felt much more intentional than jumping between unrelated problems.
It helped me stop fearing unfamiliar questions
One unexpected benefit was how much calmer I became during practice.
Previously, seeing a new problem immediately made me nervous. Now my first question became:
"Which pattern does this resemble?"
That small mindset shift reduced a surprising amount of interview anxiety.
Even when I couldn't immediately solve a problem, I usually had a reasonable starting point because I had already seen similar approaches in other contexts.
That confidence is difficult to measure, but it made a noticeable difference during mock interviews.
Things I appreciated the most
| Feature | Why it mattered |
|---|---|
| Pattern-first approach | Helped recognize solutions instead of memorizing them |
| Progressive difficulty | Built confidence gradually |
| Interactive coding environment | No setup required to practice |
| Multiple programming languages | Easy to prepare using my preferred language |
| Mock interviews | Simulated real interview conditions |
None of these features replace consistent practice. What they do is make your practice significantly more focused.
Who I think should take this course
If you've already solved several hundred LeetCode questions and naturally recognize patterns, you may not gain as much value from the introductory sections.
However, if you're somewhere between beginner and intermediate, I think this course fills an important gap.
It's especially valuable if you often understand solutions after reading them but struggle to discover those solutions on your own.
That was exactly where I found myself.
My final thoughts on the Best Grokking Coding Interview Patterns Course
If someone asked me today to recommend the Best Grokking Coding Interview Patterns Course, I'd comfortably point them toward Educative's Grokking the Coding Interview Patterns.
- Not because it promises shortcuts.
- Not because it eliminates the need for practice.
But because it teaches something that many interview resources overlook:
How to recognize the underlying strategy before writing a single line of code.
That skill matters far more than memorizing hundreds of isolated solutions.
The course now covers 28 coding patterns, 500+ interactive challenges, 17 mock interviews, and a structured roadmap designed to help engineers recognize problem-solving patterns rather than simply repeat previously seen questions.
For me, that shift completely changed how I prepared for coding interviews.
I still use LeetCode. The difference is that now I'm no longer trying to memorize every problem. I'm looking for the pattern hiding underneath it.
And honestly, that's probably the most valuable lesson I took away from the course.
