The UPSC (Union Public Service Commission) exam is one of the most prestigious and challenging examinations conducted in India. It is conducted by the UPSC, which is a constitutional body responsible for recruiting candidates for various civil services posts in the government of India. The exam is held annually and consists of three stages: the preliminary examination, the main examination, and the personality test (interview).

The UPSC exam is known for its vast syllabus and high level of competition. It tests candidates' knowledge, analytical abilities, problem-solving skills, and decision-making capabilities. The exam requires extensive preparation, including studying current affairs, mastering subject knowledge, practicing writing skills, and honing one's interview skills.
