⚠️ COMMON INTERVIEW MISTAKE #6 (BONUS) - Memorizing Solutions Instead of Understanding Patterns

Grinding 300 LeetCode problems by memorizing each specific solution is a losing strategy - the moment an interviewer changes ONE constraint, memorized solutions fall apart, because there was never any real understanding underneath them.

✅ The better strategy: learn the ~15 underlying PATTERNS (sliding window, two pointers, BFS/DFS, dynamic programming, backtracking, heaps, intervals, topological sort, and a few others), and practice recognizing which pattern a NEW, unfamiliar problem maps to.

A genuinely strong signal in interviews: when given a twist on a problem you've never seen ("now the array is sorted" or "now you need the top K instead of just one"), you can reason your way to the adjusted solution live, instead of freezing because it doesn't match anything memorized.

Quick self-test: could you solve a completely novel problem using the sliding window pattern right now, without looking anything up? If not, that's a sign to focus on the underlying technique, not another 20 random problems.

Which pattern do you feel weakest on right now? Let's crowdsource some practice problems for it in the comments 👇
