CS Foundations & Interview Prep

Master Arrays, Linked Lists, Hash Tables, Trees, and Graphs - and know when each shines.

Learn the two-pointer and sliding-window patterns that unlock a huge class of array and string problems.

Recognize overlapping subproblems and derive recurrences - the pattern most interviews test and most candidates fear.

Master tree traversals and graph algorithms (BFS/DFS, shortest paths, topological sort) as reusable interview patterns.

Close the high-value pattern gaps with binary search on answers, intervals, heaps, monotonic stacks, backtracking, tries, greedy proofs, and bit reasoning.

Understand Git from the object model up - blobs, trees, commits, and refs - so version-control questions never trip you up.

Apply SOLID principles and classic patterns (Factory, Strategy, Observer) to reason clearly in design rounds.

Practice the complete interview loop with clarification, baseline-to-optimal reasoning, communication rubrics, deliberate testing, and timed mock interviews.
