About this course

A practical run through the data structures and algorithms you'll actually meet in interviews and in production code: arrays, trees, graphs, and the patterns (two-pointer, sliding window, traversal) that make hard problems tractable.

What you'll learn

  • Recognise which data structure fits a given problem
  • Analyse time and space complexity with confidence
  • Solve two-pointer, sliding window and graph problems
  • Walk through your reasoning clearly in a live interview
  • Practice with a full mock coding interview

I went into my interview last week and the framework from this course carried me through it.

Some sections feel a little dense, but rewatching at 0.75x speed fixed that for me.
