Practicing Real Interview Thinking Solved a palindrome problem today — without using reverse. At first, I thought checking first and last character is enough. But I realized the correct approach is to compare characters from both ends step by step. This changed my thinking: Interview problems are not about complexity, but about correct logic. Small problems → Big learning. #Java #ProblemSolving #InterviewPrep #LearningInPublic

Day15 #100 days of leetcode One of the most asked string problems in interviews — and a great way to sharpen your problem-solving skills. 🔍 Problem Given a string, find the longest substring that reads the same forward and backward. 💡 Approach Used: Expand Around Center Instead of checking every substring (which is expensive), we treat each character as a center and expand outward. #DataStructures #Algorithms #Java #CodingInterview #LeetCode #ProblemSolving #TechCareers

🚀 A small #learning from my recent interview In one of my recent interviews, I was asked to write a program to create a deadlock and then explain how to fix it. Honestly, I’ve read about deadlocks before, but writing it during an interview made me think more practically. 𝐓𝐰𝐨 𝐭𝐡𝐫𝐞𝐚𝐝𝐬, 𝐭𝐰𝐨 𝐫𝐞𝐬𝐨𝐮𝐫𝐜𝐞𝐬: Thread 1 locks one resource and waits for the other Thread 2 does the opposite And that’s it… both threads are 𝐬𝐭𝐮𝐜𝐤 𝐟𝐨𝐫𝐞𝐯𝐞𝐫 What I liked about this question is — it’s simple, but it checks how well we understand real-world thread behavior. The discussion didn’t stop at just creating the deadlock. The interviewer was more interested in how I would avoid it. 𝐒𝐨𝐦𝐞 𝐤𝐞𝐲 𝐭𝐚𝐤𝐞𝐚𝐰𝐚𝐲𝐬 𝐟𝐨𝐫 𝐦𝐞: --> Always follow a consistent order while acquiring locks --> Be careful with nested synchronization --> Think about alternatives like tryLock or timeouts It was a good reminder that multithreading is not just about writing code, but about writing safe and predictable code. #Java #Multithreading #Concurrency #JavaDeveloper #BackendDevelopment #SoftwareEngineering #InterviewExperience #TechInterview #CodingInterview #Learning

🚀 Wissen Interview Experience – Round 1 Hey folks! 👋 Just wrapped up an interview round that was a solid reminder of one thing: => If your fundamentals are weak, nothing else matters. Here’s what was covered: 1. SQL Aggregation using GROUP BY Sorting results based on computed values 2. Multithreading (Deep Dive) Printing sequence using 3 threads (real concurrency control) Runnable vs Callable Future vs CompletableFuture ExecutorService AtomicInteger CAS 3. Collections HashSet behavior with equals() and hashCode() Real-world bug: modifying object after insertion Immutability and its importance 4. DSA Remove duplicates from sorted array (two-pointer) Follow-up: allow at most 2 duplicates 5. Core Java Concepts equals() vs hashCode() contract Identifying immutable classes Usage of static 7. System Design Thinking Handling latency across environments (dev/stage/prod) Managing sudden traffic spikes after fixing bottlenecks 8. HashMap Internals Internal structure Collision handling Rehashing Java 7 vs Java 8 changes Key Takeaway Master the basics. Seriously. Because interviews don’t fail you on advanced topics. They fail you on things you thought you already knew. Let’s grow together! 🚀 Feel free to connect if you're also preparing for backend interviews—always happy to share notes and learn together.

Code is easy, but concepts are the real filter. Just watched a solid interview simulation by Sheryians Coding School, and it was a massive reality check. In the age of AI prompts, the real winners are those who actually understand what’s happening "under the hood." The 3-Step Reality Check: 1️⃣ JS Basics: It’s not just let/const; it’s the Temporal Dead Zone. 2️⃣ The Core: If you don’t get Execution Context or Closures, you don’t know JS. 3️⃣ The Final Boss: Mastering the Event Loop separates the seniors from the juniors. The lesson? It’s not just about the answer - it’s about your technical depth and how you structure your thoughts.
