Most developers prepare for interviews by practicing frameworks… But interviews still start with logic and problem-solving. And that’s where many candidates struggle. After taking multiple interviews, I’ve noticed something: 👉 Strong developers don’t just code 👉 They think clearly under pressure So here are some commonly asked logical + coding questions you should be ready for: 🧠 Logical Thinking Questions Reverse a string without using built-in functions Find missing number in an array (1 to N) Detect duplicate elements efficiently Check if a string is palindrome Find first non-repeating character Two Sum problem (target-based pairs) Valid parentheses problem Find intersection of two arrays FizzBuzz (simple but revealing) Find majority element in array 💻 Coding & Problem-Solving Implement a stack/queue from scratch LRU Cache (very common for senior roles) Binary search implementation Merge two sorted arrays Detect cycle in linked list Reverse a linked list Implement basic REST API (CRUD) Write SQL query for top N records Optimize a slow query Design a simple rate limiter ⚡ What Interviewers Actually Look For It’s NOT just the final answer. We evaluate: ✔ How you approach the problem ✔ How you break it down step by step ✔ How you handle edge cases ✔ Code clarity and structure ✔ Your ability to explain your thinking 💡 Reality Check If you: ❌ Jump directly into coding ❌ Don’t clarify requirements ❌ Ignore edge cases You’ll likely struggle—even if you know the solution. 📌 How to Prepare Smartly Practice 3–5 problems daily Explain your solution out loud Focus on approach > syntax Revisit problems and optimize 📩 Want deeper preparation?
