The UPSC exam is distinct from other competitive exams in India due to its comprehensive nature, covering *preliminary*, *mains*, and *interview* stages. It emphasizes *general studies*, *aptitude*, and *current affairs*, integrating a holistic evaluation of candidates. Other exams often focus solely on multiple-choice questions or specific subjects. The UPSC also prioritizes *constitutional knowledge* and *ethical considerations*, assessing critical thinking and problem-solving skills beyond rote learning, making it unique in its rigorous selection process.
