Indian Engineering Services comprise of engineers who work under the government of India and designated as Class – 1 officer. They administer a large segment of the public sector economy, which constitutes of Indian Railways, Power, Telecommunications, Central Water engineering, Defense service of Engineers, Central Engineering Service, etc. The nature of work performed by these bureaucrats largely depends on their engineering branch and the service or cadre they are recruited in. The career progression goes smoothly attaining high esteem. The first position offered is that of Asst. Executive engineer and the hierarchy ends at the position of Chairman/ Managing Director.
A combined competitive examination is conducted by the Union Public Services Commission (UPSC) for recruitment to the Indian Engineering Services. The Examination constitutes of a written examination followed by an interview for the personality test.
