The Intelligence Bureau (IB) is India’s internal intelligence agency and reputedly the world’s oldest intelligence agency. It was recast as the Central Intelligence Bureau under the Ministry of Home Affairs. The Intelligence Bureau is used to garner intelligence from within India and to execute counter-intelligence and counter-terrorism tasks. The Bureau comprises employees from law enforcement agencies, mostly from the Indian Police Service (IPS) or the Indian Revenue Service (IRS) and the military. The recruitment in IB is based on class level group A gazetted officers, group B Senior inspector, group C grade 2 officers and group D. Candidates should keep in mind that they can be posted anywhere in India.

IB demands selflessly working for the nation, and so it is search of candidates who are well aware of the issues the nation is dealing with. Other information regarding this vacancy includes-
