🚀 Started doing free mock interviews this week — and wow, there’s a lot to learn. From timing under pressure to refining problem-solving strategies. One step at a time. I’ll get there. 💪 #TechInterviews #MockInterviews #CodingPrep #SystemDesign #LeetCode #DSA

🧩 LeetCode 90: Subsets II Duplicates? In my subset generator? Sort 'em, skip 'em, move on. Like dodging your ex at the grocery store — once is enough. Subsets, but smarter. 😎 100% performance #LeetCode #Backtracking #CodingHumor #DevLife #CSharp

LeetCode 79. Word Search — “Medium”? Not really. Backtracking DFS Matrix traps = 🔥 TLE if brute. Bugs if mutate. O(nmL) if pro. This one tests your full stack of recursion skills. #LeetCode #Backtracking #CodingInterview #DevHumor #AlgoDaily #DFS

Task: “Sum of Prefix Scores of Strings” Me: “Oh cool, sounds like a sliding window or hashmap thing.” Problem: “Nope. It’s TRIE time 😈.” #LeetcodeHard #DSA #CodingInterview #DevHumor #TechLife #SystemDesign #CSharp #CleanCode #CodingMeme #Blind75 #GoogleInterview #MetaInterview

Why is BFS the Beyoncé of Meta interviews? 15 years into my career, and I've never needed it. Are they testing fundamental logic or just seeing if we remember college? This "main shizzle" needs explaining #MetaInterviews #BFS #TechInterviews #SoftwareEngineering #CareerQuestions

Been building a private AI thing that helps me prep smarter for tech interviews. Think: instant feedback, tailored guidance, always-on mentor vibes. Might open it up. Would you use something like this? #AI #TechInterview #DSA

Actually now I think it's nice to know that I can do it on my own, without using the AI for this. BTW: Thanks to ChatGPT I've completely covered the In-Order traversing and PostOrder, PreOrder and so much more... #leetcode #bst #datastructures #ds #binarytree
