Is using LeetCode worth it? 5 Key Things to Consider.
Using LeetCode for practicing coding problems can be highly beneficial, especially for software engineers and computer science students preparing for technical interviews or looking to improve their problem-solving skills.
In this post, we'll cover five key aspects that will help you decide. From its effectiveness in sharpening your skills to how it stacks up against alternatives (like CodeSignal, HackerRank, Codeforces, and DesignGurus.io), we'll also dive into whether LeetCode Premium is a smart investment, how pattern-based learning (championed by DesignGurus.io) compares to grinding LeetCode problems, and the overall pros and cons of using LeetCode.
1. Advantages of Using LeetCode
-
Comprehensive Problem Set: LeetCode offers a wide range of problems covering various topics, such as data structures, algorithms, databases, and system design. This variety helps users build a broad base of coding skills.
-
Preparation for Technical Interviews: Many companies use coding interviews to assess candidates' problem-solving abilities. Practicing with LeetCode can prepare you for the types of questions asked in interviews with tech companies, including FAANG (Facebook, Amazon, Microsoft, Netflix, Google).
-
Learning Platform: LeetCode provides detailed solutions and discussions for each problem, allowing users to learn different approaches and best practices. It's also a dynamic platform with new problems added regularly.
-
Community and Competitions: LeetCode has a large community of users. Participating in discussions and competitions can motivate you, help you gauge your progress against others, and expose you to more diverse problem-solving methods.
-
Skill Improvement: Regular practice on LeetCode can significantly enhance your coding skills, logical thinking, and ability to tackle complex problems efficiently.
2. LeetCode vs Alternatives (CodeSignal, HackerRank, DesignGurus.io)
LeetCode might be popular, but it's certainly not the only platform out there. How does it compare to other coding practice platforms and resources? Below is a quick comparison of LeetCode with a few notable alternatives – CodeSignal, HackerRank, Codeforces, and DesignGurus.io – each of which has its own strengths:
-
CodeSignal: This platform offers a mix of interview practice challenges and gamified learning. One standout feature of CodeSignal is its “Arcade” mode that turns practice into a game-like progression, which can be motivating. It also provides standardized coding assessments (scores that some employers recognize) and company-specific challenge tracks (What are LeetCode Alternatives?). However, CodeSignal’s problem library is a bit smaller compared to LeetCode’s, and some of its premium features (like certain prep tests or advanced content) come at a cost (Which coding platform is best for interview preparation?). In short, CodeSignal is great for keeping practice fun and for getting a measurable score or certificate, but if you want the absolute largest set of practice problems, LeetCode still wins on quantity.
-
HackerRank: HackerRank is another hugely popular platform, known for its broad range of domains and more guided experience for beginners. It has tons of challenges not just in algorithms and data structures, but also in areas like SQL, mathematics, regex, and even language-specific challenges. HackerRank provides structured preparation kits and tutorials (for example, 30-day challenge, interview preparation kit, etc.), which can be very helpful if you like a more guided roadmap. LeetCode focuses almost entirely on algorithms/datastructures for interviews. HackerRank might be better if you are just starting out or want to cover foundational topics with more hand-holding – it’s “more beginner-friendly,” with hints and a broader range of topics (What's better than LeetCode?).
-
DesignGurus.io (Coding Interview Courses): DesignGurus.io isn’t a problem-solving “judge” platform like the others, but rather an educational resource offering curated courses for coding interviews and system design. It takes a unique approach: instead of throwing thousands of random questions at you, DesignGurus.io teaches “coding patterns” and provides structured lessons to tackle coding problems smarter. For example, their Grokking the Coding Interview course organizes problems by 25+ fundamental patterns (Sliding Window, Two Pointers, BFS/DFS, etc.), walking you through each pattern with examples. This pattern-based approach helps you “map a new problem to an already known problem,” making it easier to solve unfamiliar questions by recognizing similarities to ones you've seen before (Don’t Just LeetCode: Follow Coding Patterns for Smarter Prep). In terms of content, DesignGurus also covers areas LeetCode doesn’t directly teach, like system design interviews, behavioral tips, and mock interview scenarios .
3. Challenges of Using LeetCode
-
Overwhelming Set of Coding Questions: One can get overwhelmed by the huge number of coding problems on LeetCode. An alternative approach could be to follow the coding patterns. These patterns help demystify complex coding problems by teaching you to recognize underlying patterns, such as sliding window, two pointers, two heaps, etc. This makes it easier to tackle similar problems in the future.
-
Time Investment: Achieving proficiency through LeetCode requires a significant time investment. It's important to balance this with other studies, work, and personal projects.
-
Learning Curve: Beginners may find some of LeetCode's problems challenging. Starting with easier problems and gradually increasing the difficulty level can help mitigate this.
-
Overemphasis on Algorithmic Puzzles: While LeetCode is excellent for algorithmic practice, real-world software engineering often involves broader skills, including system design, project management, and collaboration. It's crucial to develop these skills alongside algorithmic problem-solving.
4. LeetCode Premium: What Do You Get, and Is It Worth the Money?
As you use LeetCode, you’ll notice some features are locked behind a paywall – this is LeetCode Premium, a subscription service. What does Premium offer, and do you really need it to succeed? Let’s break down the value of LeetCode Premium:
Benefits of LeetCode Premium:
- Company-Specific Questions: Premium users can filter and access problems by specific companies (Google, Amazon, Microsoft, etc.). This means you can practice exact questions that have been frequently asked in real interviews at those companies. For someone targeting a particular employer, this feature is extremely handy – you get a curated list of “top X company” problems.
- Premium-Only Problems: LeetCode Premium unlocks a set of additional problems not available to free users. These are often more niche or challenging questions. If you’ve exhausted a lot of the free content or want to be extra thorough, these give you more to chew on.
- Detailed Solutions & Insights: Premium provides official problem solutions and sometimes detailed editorials for problems, which can be more consistent in quality. While free users do have access to community discussions and some official solutions for certain problems, Premium guarantees you get LeetCode’s in-depth explanations for all premium problems and some additional stats (like difficulty frequency, acceptance rates, etc.). There are also features like problem frequency, which shows how often a question has been asked in interviews (based on user feedback), and a filtering by frequency for Premium users.
- Mock Interviews and Interview Tools: LeetCode Premium includes an interview simulator where you can run through a set of questions in a timed environment, simulating a real interview. It also gives you access to virtual contests and some exclusive contest problems. These tools can be useful for assessing your readiness. (Note: The exact feature set may evolve, but generally Premium adds some convenience tools for interview prep beyond just the questions.)
Considerations (Drawbacks) of Premium:
- Cost: The most obvious consideration – Premium requires a subscription (monthly or annual). For some, especially students or those on a tight budget, this cost can be significant. You’ll want to be sure you’ll actually use the features before paying. If you only need to solve common interview questions, note that many lists of important problems (like “Top 100 interview questions” or the popular “Blind 75” list) are available for free online, and community-curated study guides exist that mimic the company-specific sets. Paying for Premium is only worth it if those added features will meaningfully boost your prep.
- Volume Over Strategy: LeetCode’s approach, Premium or not, is still largely about grinding through lots of problems. Premium increases the volume of problems available, but doesn’t inherently change how you practice. Some critics point out that solving hundreds of questions can turn into a brute-force, rote activity if you’re not careful. The platform itself doesn’t emphasize learning generalized techniques or patterns – that part is up to you. As Design Gurus mentions, LeetCode (even with Premium) “doesn’t always emphasize understanding underlying patterns, which is crucial for problem-solving efficiency”. In other words, it’s possible to waste a lot of time on LeetCode if you treat it as just a checklist of problems, instead of extracting lessons from each question. Premium gives you more content, but you’ll still need a smart approach to get the most out of it (more on that in section 5).
- Alternatives to Premium: It’s worth noting that LeetCode’s free tier is extremely robust on its own – you have hundreds of questions (including most of the classics) and access to the community discussion solutions. Many candidates have cracked interviews without paying a dime, by leveraging free problems and community insights. Additionally, alternative resources can fill in gaps: for example, Grokking the Coding Interview (a DesignGurus.io course) is often cited as a great structured way to learn patterns instead of paying for LeetCode Premium. That course isn’t free either, but it offers a different kind of value (education and structure) if that’s what you need. Some people invest in a month of LeetCode Premium close to their interviews just to get company questions and solutions, then cancel – others skip it entirely and rely on free resources.
So, is Premium worth it? The answer depends on your situation:
- If you are targeting specific companies and want to make sure you cover those companies’ favorite questions, Premium can save you time by organizing those for you. It’s also useful if you like having official solutions and a polished interface for mock interviews.
- If budget is an issue, or you prefer a more guided learning approach, you might skip Premium. You can find lists of company questions crowdsourced by others, and use books or courses (like Design Gurus’ Grokking the Coding Interview) to guide you through patterns and solutions. These can be very effective alternatives without needing a subscription.
- Another strategy: use free LeetCode to practice widely, and if you feel you’ve exhausted what you need or want that extra edge, subscribe to Premium for a short period. Some users report that Premium is most worth it in the final stretch of interview prep – when you’re polishing up and want to ensure no surprises, you can binge the company-tagged questions and read solutions for tricky ones.
5. Pattern-Based Learning vs. LeetCode’s Problem-Solving Methodology (DesignGurus.io’s Approach)
One of the hottest debates in coding interview prep is quality vs. quantity: should you grind through hundreds of LeetCode problems, or focus on learning a smaller number of key patterns and techniques that can be applied broadly? This is where the DesignGurus.io coding pattern approach comes in, offering a different methodology compared to the traditional LeetCode grind. Let’s explore how these approaches differ and the benefits of the pattern-based strategy.
LeetCode’s Method: Lots of Problems, Self-Driven Learning. LeetCode essentially gives you a huge bank of problems and a platform to solve and discuss them. The onus is on you to choose which problems to solve, figure out the relevant technique, and learn from solutions if you get stuck. While LeetCode provides tags and difficulty levels, it doesn’t inherently guide you through a learning progression – which can make it overwhelming. “The biggest challenge with LeetCode is its lack of organization; it has a huge set of coding problems, and one isn’t sure where to start or what to focus on,” notes one Design Gurus blog. There are over 2,000 problems; if you approach them randomly, you might cover a lot of ground but still feel scattered. Many people fall into the trap of solving problem after problem without seeing the common threads between them. This is why you’ll hear advice like “don’t just grind blindly” – you want to learn patterns, not just individual solutions.
DesignGurus.io’s Pattern-Based Approach: In contrast to solving by sheer volume, DesignGurus (and some other resources) advocate learning by mastering key algorithmic patterns. The idea is that almost any coding interview question can be reduced to one of a few dozen basic patterns. For example, many array or string problems use a Sliding Window pattern, many linked list or array traversal problems use Two Pointers, tree problems often use DFS/BFS traversal patterns, etc. DesignGurus.io’s Grokking the Coding Interview course identifies about 16-20 core patterns (like Sliding Window, Two Pointers, Fast & Slow Pointers, Merge Intervals, Cyclic Sort, etc.) and teaches each one with multiple examples. Once you learn the general approach for, say, “Sliding Window”, you’ll recognize when a new problem can be attacked with that technique. This approach builds your ability to “map a new problem to an already known problem”, which is hugely valuable during interviews. Instead of starting from scratch each time, you recall “oh, this looks like a sliding window problem I solved before” and you have a game plan right away.
How the Pattern Approach Differs in Practice: With a pattern-focused study plan, you would organize your practice by pattern or topic rather than random questions. For instance, you might spend a day or two fully understanding the Two Pointers pattern – what kinds of problems use it, how to approach them – and solve several two-pointer problems in a row to reinforce the pattern. This structured learning path ensures you cover all important techniques without getting lost in the weeds. DesignGurus.io emphasizes this structured path: “the course is organized around these patterns, providing a step-by-step learning path that builds your problem-solving skills”. It’s a bit like studying smart instead of just hard. LeetCode by itself doesn’t stop you from doing pattern-based practice (in fact, you can manually select problems by tags or use community-made lists), but it “focuses more on quantity over structured learning” by default. With a patterns approach, the focus is on understanding why a solution works and seeing the connections between problems.
Benefits of the Pattern Approach: The main benefit is efficiency. You potentially solve fewer total problems but extract more general knowledge from each. It can be less overwhelming and more encouraging, because you feel a sense of progression as you master one pattern after another. Many candidates report that once they learned patterns, new LeetCode problems became easier to solve because they could quickly identify which pattern to apply.
In summary, the pattern-based approach is a smarter way to navigate LeetCode-style questions. It complements LeetCode by providing the organization and strategy that LeetCode alone lacks. If you’ve felt lost or burnt out doing random LeetCode questions, consider shifting to a pattern-oriented study plan. Many successful interviewees swear by focusing on patterns to drastically cut down the number of questions they needed to do while still covering everything important.
Conclusion
Whether LeetCode is worth it depends on your goals. If you're preparing for technical interviews, especially with major tech companies, or if you wish to sharpen your problem-solving skills, LeetCode can be an invaluable resource. However, it's also essential to maintain a balanced approach to learning and development, incorporating practical software engineering skills and other forms of technical knowledge beyond just solving algorithmic problems.
