How to prep for coding interviews

Coding interviews usually come in one of three flavors. The classic algorithmic round (LeetCode-style, 30-45 minutes, pattern recognition + complexity). The coding challenge round (an open-ended build prompt like "make a key-value store" where requirements arrive in phases and you ship against live tests). And the code review round (here's a snippet, find the bug, explain why it breaks). A real loop might throw two or three of these at you across separate rounds.

This course covers all three. Pattern primers with visual walkthroughs for the algorithmic stuff. Real coding challenges that run in your browser for the build rounds. Deep dives on where bugs hide for code review. And when you're ready, live mock interviews that grade you against an actual interviewer rubric.
