Technical Interview Prep, Free
The coding interview is a game you can learn to play. Follow a structured plan instead of grinding random problems — these free resources are the ones that actually get people hired. All current.
Technical interviews test a specific, learnable skill set: data structures, algorithms, and explaining your thinking out loud. The mistake most people make is grinding hundreds of random problems. Instead, follow a curated plan, learn the patterns behind the problems, and practice deliberately. Start with a structured guide, then drill the patterns.
01 · A STRUCTURED PLAN
Prep the smart way
Guides that tell you exactly what to study and in what order.
- Tech Interview Handbook ↗A free, comprehensive guide covering the entire process — a study plan, the best practice questions, behavioral prep, and negotiation.techinterviewhandbook.org
- NeetCode ↗A free, curated roadmap of the essential coding problems grouped by pattern, with clear video explanations. The efficient path to fluency.neetcode.io
02 · PRACTICE
Drill the problems
Where to actually solve problems and build speed.
- LeetCode ↗The standard platform for coding-interview practice — thousands of problems with a large free tier. Follow a curated list rather than solving at random.leetcode.com
- Big-O Cheat Sheet ↗The complexity reference every candidate revises from — time and space costs for every common data structure and algorithm.bigocheatsheet.com
