I couldn't afford interview prep, so I built a free alternative

In plain words

This free platform helps job candidates prepare for technical interviews at major technology companies. It covers data structures, algorithms, and system design through interactive visualizations, a Python code editor, and AI-generated feedback on solutions. The tool includes progress tracking to help users work through structured lessons at their own pace, designed for those who cannot afford traditional interview preparation courses.

From the sources

Structured prep covering the data structures and algorithms big-tech interviews expect. Interactive visualizations, a Python playground, AI-powered feedback, and progress tracking. Given an array of integers `nums` and an integer `target`, return the indices of the two numbers that add up to `target`. Each input has exactly one solution. You may not use the same element twice. learningto/pass is built for a bigger screen. Feel free to look around - the code editor and visualizations work best on a laptop orfrom learningto.co
