If you’re preparing for coding interviews and want to leverage Grokking the Coding Interview with the help of Reddit, here’s a structured approach to making the most of both resources.
1. Understanding Grokking the Coding Interview
Before exploring how Reddit can help, it’s important to understand what Grokking the Coding Interview offers.
What is Grokking the Coding Interview?
It is an interactive course designed to teach coding interview patterns, rather than just individual problems. The main focus is on recognizing problem-solving techniques that can be applied across different questions. Some of the key patterns include:
- Sliding Window
- Two Pointers
- Fast and Slow Pointers
- Merge Intervals
- Top K Elements
- Graph Traversal
This structured approach helps learners build a solid foundation for tackling a variety of coding problems.
Why is it Popular?
Many candidates struggle with coding interviews because they focus on solving individual problems rather than understanding patterns. This course addresses that issue by teaching reusable techniques, making problem-solving more systematic.

3. Creating an Effective Study Plan with Reddit’s Help
Using Grokking the Coding Interview effectively requires a structured plan. Here’s a step-by-step guide to combining it with Reddit insights for better preparation.
Step 1: Understand Your Timeline
Determine how much time you have before your interview. Based on Reddit discussions, many users recommend spending 6-8 weeks on structured preparation. If you have less time, focus on the most commonly asked patterns.
Step 2: Follow a Pattern-Based Approach
Instead of solving random problems, follow a structured pattern-based approach:
- Pick a pattern from Grokking the Coding Interview (e.g., Sliding Window).
- Understand the theory and example problems.
- Search on Reddit for discussions about that pattern (e.g., “Sliding Window coding interview tips”).
- Solve additional problems from LeetCode related to that pattern.
- Move to the next pattern once you’re comfortable.
Step 3: Use Reddit to Identify Important Topics
Reddit users frequently discuss which coding topics appear most often in real interviews. Some common recommendations include:
- Graphs and Trees (BFS, DFS)
- Dynamic Programming
- Arrays and Strings (Sliding Window, Two Pointers)
- Sorting and Searching
Adjust your study plan to focus on the most frequently tested concepts.
Step 4: Practice Mock Interviews
After finishing the patterns, start doing timed practice questions. Some useful methods:
- Use LeetCode’s mock interview feature.
- Join a study group on Reddit (some users form small Discord or Slack groups).
- Use Pramp or Interviewing.io for live mock interviews.
Reddit threads often have links to free or community-organized mock interview sessions.
4. Common Questions About Grokking the Coding Interview on Reddit
Is Grokking the Coding Interview Worth It?
Many Reddit users have mixed opinions. Some say it’s useful for beginners because it teaches patterns systematically, while others argue that LeetCode premium provides a better selection of problems.
If you’re struggling to identify patterns in problems, this course can be valuable. However, if you already have experience with problem-solving, you might prefer solving problems directly on LeetCode.
Should I Use It Instead of LeetCode?
No. Most Reddit users suggest using Grokking the Coding Interview as a supplement to LeetCode. The best approach is to:
- Learn patterns from Grokking the Coding Interview.
- Solve additional problems on LeetCode.
- Use Reddit to find alternative explanations and additional resources.
How Much Time Should I Spend on This Course?
Many Reddit users recommend spending 3-4 weeks to go through the main patterns, with 1-2 weeks of additional problem-solving. If your interview is soon, focus on the most commonly tested patterns.
What Are Good Alternatives?
If you’re looking for free or alternative resources, Reddit users often suggest:
- NeetCode’s curated problem list
- LeetCode’s “Top Interview Questions”
- AlgoExpert (for structured problem explanations)
- Cracking the Coding Interview (for additional theory)
