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

Learning to pass the interview Structured prep covering the data structures and algorithms big-tech interviews expect. Interactive visualizations, a Python playground, AI-powered feedback, and progress tracking. Solve a real Google interview question, right here 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.

Feel free to look around - the code editor and visualizations work best on a laptop or desktop.
