DSA Interview Mastery

A personal interview playbook covering core patterns, explanation templates, debugging checklists, and graded practice sets

Interview Mindset and Complexity Reasoning - Establish how strong candidates think aloud, reason about complexity, and turn vague prompts into structured solution plans.

Two Pointers and Sliding Window - Turn ordered traversal into a pattern the reader can recognize quickly under interview pressure.

Trees, Recursion, and Traversal Patterns - Establish recursive thinking, tree traversal templates, and the discipline of passing state through call stacks carefully.

Heaps, Greedy Methods, and Interval Problems - Build fast access to extremal elements and teach when local greedy choices can be justified.

Tries, Bit Tricks, and Designing Custom Data Structures - Give the reader a controlled introduction to less frequent but high-signal topics that still appear in top-tier interviews.
