LeetCode vs Real World Problem Solving

So are LeetCode and HackerRank dead? Not really. But pretending that solving 2 D array puzzles in 27 minutes is the best way to hire for real engineering work is getting harder to defend. Especially now. When developers are building with AI copilots, shipping APIs, debugging distributed systems, designing LLM workflows, handling scale, and making production tradeoffs we are still asking them to reverse a linked list on a shared screen like it is 2016. The funny part is this: -Companies say they want builders. -But many hiring processes still select for people who are best at clearing academic style speed tests. LeetCode is not useless. It still checks problem solving, basics, and some level of discipline. But if that becomes the main filter, then recruitment is not broken because candidates are weak. It is broken because the process is outdated. Hiring now needs to evolve. Test fundamentals, yes. But also test design thinking. Debugging. Communication. Use of tools. Judgment. Ability to build something that actually works outside an interview document. Because in real jobs, nobody gets promoted for finding the longest palindrome substring in 18 minutes. They get promoted for solving business problems reliably. LeetCode is not dead. But recruitment that stops at LeetCode probably should be. #learning #technology

350 problems on LeetCode — and the hardest part wasn’t solving them I recently crossed 350 problems on LeetCode. At the start, it felt like a numbers game. Solve more, get better. But somewhere along the way, that idea changed. Because the real progress wasn’t in the count—it was in how I started thinking. Sitting with a problem that made no sense, and choosing not to move on Debugging the same logic again and again until it finally clicked Realizing that most mistakes come from unclear thinking, not lack of knowledge Learning to stay patient when nothing seems to work There were days when even simple problems felt difficult. Days where progress felt invisible. But that’s the part no one talks about. Improvement in problem solving is slow. It’s subtle. You don’t notice it day to day—but one day, things just feel easier. Patterns start repeating—DP, graphs, sliding window, and more. Your approach becomes more structured. And problems that once felt impossible start to feel manageable. The biggest shift wasn’t in skill. It was in mindset. You stop chasing quick answers. You start trusting the process. 350 is just a checkpoint. But it taught me something I’ll carry forward: Progress doesn’t come from motivation. It comes from showing up—even when it feels like you’re getting nowhere. On to the next milestone. #LeetCode #DSA #ProblemSolving #Consistency #GrowthMindset

Nobody talks about this part of being a developer… It’s not the coding. It’s the frustration before the solution. The moment when: • Nothing works • Errors don’t make sense • You feel like you forgot everything And then suddenly… 💡 It clicks. And that same problem that felt impossible becomes “easy”. That’s the real developer journey. Not knowing → Struggling → Figuring it out → Growing 🚀 If you’re stuck right now, you’re probably closer than you think.

Good morning. In coding, your “sweat” shows up as the long hours, the bugs you refuse to ignore, and the patience to keep going when nothing works at first. Every error you debug and every challenge you push through is part of the process. It may not be easy, and it may not be visible, but that effort is what builds real skill. Keep showing up, keep solving, and keep improving—because the code you struggle with today becomes the strength you rely on tomorrow. 💻🔥 #Tech #Dev #FrontendDev

Not all loops are written in code. Some are lived daily: Chai → Code → Chai Behind every product, feature, and deployment… there’s a simple system running in the background. Consistency. Iteration. Caffeine. The real developer workflow isn’t complex ; it’s just repeated well. . . . . . #techculture #webdevelopment #codingmemes #TechHumor #FunnyTechPost [Chai and code, Chai lovers, Chai, Memes for coders. developers memes, dev life, programmer life, build in public, startup life, developers of Instagram, coding community, hustle and build, averybit solutions ]

Like a true software developer, I sat down intending to actually solve some LeetCode, but then i got completely side-tracked, and ended up building a side project instead. 😅 Standard problem sheets always made it hard for me to see the bigger picture, so I spent a weekend night "vibe coding" this: LeetGraph (https://lnkd.in/eQYDfg7u). Instead of a flat list, it visualizes the connections between problems. I scraped all the free LeetCode problems and used their "similar questions" data as the edges to construct an interactive graph. It makes it way easier to see how foundational concepts build into more complex ones and choose what to solve next. It’s just a fun weekend project for now, but if people find it useful and traffic picks up, I’ll look into scaling it! Check it out and let me know if it helps with your prep. 🕸️👨💻 #LeetCode #SoftwareEngineering #WebDev #Algorithms #DSA #CodingInterviews #VibeCoding

🚀 Grinding LeetCode. Recently I realized something important while practicing: It’s not about how many problems you solve. It’s about recognizing patterns. I used to jump between random questions… and it felt slow. Now I focus on this approach: ✅ Don’t solve randomly → Focus on patterns (Arrays → Sliding Window → Trees → Graph) ✅ Quality > Quantity → 150 well-understood problems > 500 rushed ones ✅ Stuck too long? → Learn the solution, understand the pattern, then re-code ✅ Stay consistent → 1–2 problems daily beats burnout grinding ✅ Target benchmark → Solve a new medium problem in ~20–25 minutes 💡 What I’ve learned so far: LeetCode is not just about interviews. It trains how you: break down problems think about edge cases write cleaner logic 🎯 My current focus: Strengthen DSA fundamentals Slowly move into system design & scalable backend Still early in the journey, but progress > perfection. If you're also grinding, what’s your strategy? 👇 #LeetCode #SoftwareEngineering #BackendDeveloper #CodingJourney #TechGrowth #100DaysOfCode

🔥 Most people skip the “easy” problems… I don’t. 📅 Day 40 of my LeetCode streak ⚡ Total active days: 47 Today’s problem: LeetCode 1995 – Count Special Quadruplets At first glance, it looks simple. But the real game is in how you approach it. 💡 My Approach (Brute Force – but intentional): I used 4 nested loops to check every possible combination (a, b, c, d) such that: nums[a] + nums[b] + nums[c] == nums[d] Yes, it’s an O(n⁴) solution. Yes, it’s not optimal. But here’s the point most people miss 👇 👉 I intentionally start with brute force. Because: It builds clear understanding of constraints. It ensures correctness before optimization. It trains your brain to see patterns for improvement later. 🚀 Many jump directly to optimized solutions without understanding the base logic — and that’s where growth slows down. 💭 Next Step: This problem can definitely be optimized using hashing or better approaches. That’s where I’ll head next. 📌 Key takeaway: Don’t just chase optimization. First, master the logic. Then refine it. 🔗 Problem Link: https://lnkd.in/didArNbk Consistency > Perfection. #LeetCode #Day40 #CodingJourney #ProblemSolving #DSA #Algorithms #Programming #CodeNewbie #TechGrowth #InterviewPrep #LearningInPublic #Consistency #CPlusPlus

🌙 2 AM. Everyone's asleep. The house is quiet. The world is still. But the system… wasn't okay.   I was about to close my laptop for the night — when I noticed something off in the logs. A small anomaly. Easy to ignore. Easy to call "tomorrow's problem."   𝘽𝙪𝙩 𝙄 𝙘𝙤𝙪𝙡𝙙𝙣'𝙩 𝙨𝙡𝙚𝙚𝙥.   So I opened the laptop again. 💻   ↳ Dug through the logs. ↳ Traced the issue — three layers deep. ↳ A race condition. Triggered only under a very specific load. The kind of bug that doesn't scream at you. It whispers. And whispers are the most dangerous kind. 🔇   Fixed it. ✅ Tested it. ✅ Deployed it. ✅   Closed the laptop at 3:47 AM.   ☀️ Next morning — everything was normal. No mention. No message. No "hey great catch." Just… silence.   There was no incident — because there was no incident. 🎯   And honestly? That silence felt like the loudest validation I've ever received in my career.   Because that night taught me something no course, no tutorial, no bootcamp ever could —   💡 Some of your best work will never be seen. Not in your appraisal. Not in your performance review. Not in any meeting, ever.   But YOU will know. And that quiet satisfaction at 3:47 AM — when the logs go green and the world is still asleep — That feeling is why we do this. ❤️   🌙 The lesson that stayed with me forever? The best developers aren't the ones who code the loudest. They're the ones who care even when nobody is watching. 👁️   (Swipe through the images — the night tells itself. 👆)   ♻️ Repost to appreciate the silent heroes around you. 🔔 Follow for more real talk on developer life.   #SoftwareDevelopment   #DeveloperLife   #Programming #TechCommunity   #Engineering   #CodeLife   #100DaysOfCode

Most people see "500 LeetCode solved" and see a number. I see 500 times I choose not to give up. For a long time, I viewed coding challenges as a "test" I had to pass. If I couldn't solve a problem, I felt like a failure. But somewhere around the 200-question mark, something shifted. I stopped trying to be "smart" and started being "disciplined." This journey taught me three lessons that have nothing to do with syntax: 1. The Beauty of Being Wrong: Every "Wrong Answer" was just data. It wasn't a critique of my intelligence; it was a roadmap to a better solution. 2. The Power of Compounding: You don't become an engineer by solving one hard problem. You become one by solving "easy" problems until they become second nature, then moving the goalpost. 3. Resilience is a Muscle: The frustration of a bug is temporary. The pride of solving it is permanent. Reaching this milestone was a solo climb, but having a guiding light made all the difference in navigating the most complex peaks of this journey.A special thank you to Pragati Gupta Mam, Harshit Jain Sir, and Neeraj Kumar Bharti Sir for the constant support and direction throughout this journey. Your insights helped me turn the "grind" into a path of growth. Whether you are at problem #1 or #1000, remember: The goal isn't to solve the problem. The goal is to become the person who can solve it. #Leetcode #ProblemSolving #Coding #GalgotiasUniversity
