About

Programmers (프로그래머스) is South Korea's dominant coding test and developer hiring platform. Major Korean tech companies including Kakao, Naver, and Hyundai Motor run their public coding tests on Programmers. The platform offers hundreds of algorithm problems across Levels 0–5, supporting Python, Java, C++, JavaScript, and more. It's the primary platform for anyone preparing for Korean IT company recruitment.

💡 Tips

  • If targeting Kakao recruitment, filter problems by "Kakao" to study their specific question patterns — the style is distinct from LeetCode-style problems.
  • Start with Level 0–1 to build fundamentals. Level 2+ reflects real company test difficulty.
  • After solving a problem, always read other users' solutions — shorter, more elegant code teaches you idiomatic patterns faster than any textbook.
