Our Mission

Build the Skills Top Tech Companies Demand

FaangPrep was built by engineers, for engineers. We believe that understanding algorithms visually leads to deeper comprehension and better interview performance than memorizing solutions.

Interactive Visualizers

+

Step through algorithms yourself, one state at a time — from basic sorting to advanced graph theory and dynamic programming.

Curated Problems

+

A high-yield sprint list with a day-by-day plan over two, four or six weeks and progress tracking, so preparation stays finite.

Coding Patterns

+

Learn the 17 essential algorithmic patterns (Sliding Window, Two Pointers, DP, etc.) behind the majority of FAANG interview questions.

Core Values

Our platform is built on the principles that great engineers deserve great learning tools - interactive, visual, and deeply practical.

Deep Understanding

We believe in visual, interactive learning that builds real understanding - not just pattern memorization.

Transparency

Clear pricing, open syllabi, and free-tier access so you can evaluate our quality before committing.

Quality Content

Every lesson pairs a written explanation with a visualizer and code in six languages, and every stated complexity is checked against the code. When you spot an error, tell us and we fix it.

Community First

We build for the community - free starter lessons in every topic, a free tier on the resume builder, and accessible interview preparation.
