DIG :

Civil Services examinations are competitive exams conducted by the Union Public Service Commission (UPSC) of India to recruit candidates for various civil service positions in the government of India. These exams are widely considered to be one of the toughest exams in India, with a rigorous selection process that tests candidates on their knowledge, aptitude, and leadership skills.

The Civil Services examinations consist of three stages: the Preliminary examination (Objective Type), the Main examination (Descriptive Type), and the Interview. The Preliminary exam is a qualifying exam that tests the candidate's basic knowledge and understanding of various subjects, while the Main exam is an in-depth evaluation of the candidate's knowledge, aptitude, and leadership skills.

The Civil Services examinations are held annually, and candidates who clear all three stages are appointed to various civil service positions, such as the Indian Administrative Service (IAS), Indian Police Service (IPS), Indian Foreign Service (IFS), and Indian Revenue Service (IRS), among others. These positions offer high levels of responsibility, power, and prestige, and are highly sought after by ambitious and talented individuals.
