About LeetCode
LeetCode is the site most software engineers end up on when they start preparing for technical interviews. It hosts a large library of data structure and algorithm problems, plus SQL and shell questions, each with a browser code editor that runs your solution against hidden test cases and reports whether it passed. Problems are tagged by topic and difficulty, and community discussion threads collect alternative solutions. Weekly and biweekly contests give a rating that tracks progress over time. The free account covers most problems, contests and community solutions. Premium, sold as a monthly or annual subscription, adds locked questions, official write-ups, filtering by the companies that asked a question, mock interviews and faster judging. It runs on the web with mobile apps for reading and practising. The focus is narrow: it drills interview-style puzzles rather than teaching programming from scratch, so beginners usually pair it with a course.
Best for: Developers preparing for algorithm-heavy technical interviews at tech companies.
