The Union Public Service Commission (UPSC) Civil Services Exam is one of the most competitive and prestigious examinations in India, serving as the primary route for individuals aspiring to join various civil services such as the Indian Administrative Service (IAS), Indian Police Service (IPS), and Indian Foreign Service (IFS). Conducted in three meticulously structured stages-Prelims, Mains, and the Interview-this exam evaluates candidates based on their knowledge, analytical abilities, and personal qualities, ensuring only the most capable individuals are chosen for these crucial public service roles.

This phase is conducted by a panel of expert examiners who evaluate the candidate's personality traits, such as leadership, decision-making, emotional intelligence, integrity, and the ability to handle diverse challenges.
