AlgoExpert

AlgoExpert provides a structured approach to technical interview preparation with 160+ vetted algorithm and data structure problems, each with video walkthroughs from former Google and Facebook engineers. The platform includes a built-in code editor with multiple language support and tests your solutions in real time. Problems are ranked by difficulty and grouped by category to build skills progressively.

Designed specifically for job hunters preparing for Big Tech interviews and developers wanting to sharpen algorithmic thinking. The video explanations are a major strength, though the focus on interview prep means it's less suitable for general coding education.
