30 DSA Questions Every Tech Interview Expects You to Know If you are preparing for coding interviews, your fundamentals matter more than fancy tricks. These problem-solving questions cover arrays, strings, searching, sorting, recursion, stacks, queues, and classic algorithmic patterns that interviewers use to evaluate logic, clarity, and efficiency. Work through them intentionally. Focus on understanding why a solution works, not just how to write it. Practice edge cases, optimize time and space complexity, and explain your approach clearly. Strong basics build strong confidence, and confidence shows in interviews. Save this, revise regularly, and use it as a checklist before any technical interview.

Comment "CODE" if you want the clear Brute Force and HashMap code with full explanation PDF. 🔥 Day 1 of 100 Days LeetCode DSA Challenge 🚀 Problem: Two Sum Most beginners solve this using Brute Force, which takes O(n²) time because we check every pair. But in this video, I explained how to optimize it using HashMap and reduce the time complexity to O(n). ⚡ This is how top programmers think — first brute force, then optimize. If you are starting DSA, this is the most important problem to understand HashMap concept clearly.

𝐇𝐨𝐰 𝐦𝐮𝐜𝐡 𝐃𝐒𝐀 𝐢𝐬 𝐞𝐧𝐨𝐮𝐠𝐡 𝐭𝐨 𝐜𝐫𝐚𝐜𝐤 𝐌𝐢𝐜𝐫𝐨𝐬𝐨𝐟𝐭, 𝐆𝐨𝐨𝐠𝐥𝐞 𝐨𝐫 𝐖𝐚𝐥𝐦𝐚𝐫𝐭? This is the most common DM which I get from juniors are, “Ma’am, I’ve solved 300+ questions but still can’t solve new ones. How many do I really need to do?” Here’s the truth it’s not about the count, it’s about the patterns. Once you master patterns, every new problem feels familiar. Here are the 15 patterns you must know for placements: 1. 𝐓𝐰𝐨 𝐏𝐨𝐢𝐧𝐭𝐞𝐫 𝐓𝐞𝐜𝐡𝐧𝐢𝐪𝐮𝐞 – Solve pair/relationship problems in arrays/linked lists. 2. 𝐒𝐥𝐢𝐝𝐢𝐧𝐠 𝐖𝐢𝐧𝐝𝐨𝐰 – Efficiently handle subarray/substring problems. 3. 𝐇𝐚𝐬𝐡𝐢𝐧𝐠 / 𝐅𝐫𝐞𝐪𝐮𝐞𝐧𝐜𝐲 𝐂𝐨𝐮𝐧𝐭𝐢𝐧𝐠 – O(1) lookups for counts, duplicates, mapping. 4. 𝐏𝐫𝐞𝐟𝐢𝐱 𝐒𝐮𝐦𝐬 – Answer range queries fast. 5. 𝐁𝐢𝐧𝐚𝐫𝐲 𝐒𝐞𝐚𝐫𝐜𝐡 (𝐚𝐧𝐝 𝐯𝐚𝐫𝐢𝐚𝐧𝐭𝐬) – For sorted arrays or monotonic conditions. 6. 𝐆𝐫𝐞𝐞𝐝𝐲 – Local choices that lead to global solutions. 7. 𝐃𝐲𝐧𝐚𝐦𝐢𝐜 𝐏𝐫𝐨𝐠𝐫𝐚𝐦𝐦𝐢𝐧𝐠 – Break down overlapping subproblems. 8. 𝐁𝐚𝐜𝐤𝐭𝐫𝐚𝐜𝐤𝐢𝐧𝐠 – Explore all possibilities (subsets, permutations). 9. 𝐁𝐅𝐒 – Shortest paths, level-by-level traversals. 10. 𝐃𝐅𝐒 – Explore all paths, detect cycles. 11. 𝐇𝐞𝐚𝐩 / 𝐓𝐨𝐩-𝐊 – Manage largest/smallest efficiently. 12. 𝐌𝐞𝐫𝐠𝐞 𝐈𝐧𝐭𝐞𝐫𝐯𝐚𝐥𝐬 – Handle overlaps in schedules. 13. 𝐔𝐧𝐢𝐨𝐧-𝐅𝐢𝐧𝐝 – Manage connectivity in graphs. 14. 𝐓𝐫𝐢𝐞 – Prefix-based search and storage. 15. 𝐌𝐨𝐧𝐨𝐭𝐨𝐧𝐢𝐜 𝐒𝐭𝐚𝐜𝐤 / 𝐐𝐮𝐞𝐮𝐞 – Solve next/previous greater/smaller problems. And remember, DSA is not a sprint, it is a marathon. Rejections will happen, and that is normal. But every attempt makes you sharper, and every failure teaches you a pattern in life too. #DSA #Placements #CodingInterviews #ProblemSolving #CareerAdvice #DSA #DataStructures #Algorithms #CodingInterview #LeetCode #HackerRank #Codeforces #CodeSignal #ProblemSolving #BigONotation #SystemDesign #TechCareers #InterviewPreparation #FAANG #SoftwareEngineering #CodingLife #ProgrammersLife #CareerGrowth #ComputerScience

Kindly FOLLOW the account and then comment LINK as instagram does not allow sending DMs to non-followers. DSA doesn’t have to be boring text on a screen. 🙅‍♂️💻 If you are struggling to understand trees, graphs, or sorting algorithms, you need to see them in action. Visual learning > Rote memorization.
