The Union Public Service Commission (UPSC) plays a pivotal role in public sector recruitment in India. It is responsible for conducting competitive examinations to fill various positions in the civil services, including the Indian Administrative Service (IAS), Indian Police Service (IPS), and Indian Foreign Service (IFS). The UPSC ensures that the selection process is merit-based, transparent, and fair. It also frames policies related to qualifying criteria, examination patterns, and conducts interviews to assess candidates' suitability for different posts, thereby maintaining the integrity and efficiency of public administration in India.
