What coding patterns should you master for FAANG-style interviews?

Short answer: Prioritize: Arrays/Hashing, Two Pointers, Sliding Window, Binary Search, Stack, Linked List, Trees (BFS/DFS), Graphs (BFS/DFS/topo), Heaps, Intervals, 1-D DP, Backtracking, and LRU-style design. Pattern recognition beats memorizing hundreds of problems.

Interview approach

1. Finish Blind 75 or NeetCode 150-style coverage once.
2. Timed practice: aim to solve mediums in ~25 minutes with explanation.
3. Always narrate brute force → optimize → complexity → edge cases.
4. Revisit company-tagged mediums from the last 6–12 months.

Depth on patterns beats shallow volume. Quality reps with explanation win offers.
