Algorithms
Learn sorting, searching, graph algorithms, dynamic programming, and algorithmic thinking.
Coding rounds at senior levels expose whether you pattern-match quickly or get stuck in the weeds. The signal is not memorizing solutions—it's recognizing problem type, choosing the right structure, and implementing correctly under time pressure.
These topics build a precise mental model of patterns: when to use which structure, how complexity accumulates, and how to recognize the problem type. You'll learn to reason about trade-offs, implement under constraints, and articulate your approach clearly—so you come across as someone who thinks in structure, not just code.
