Engineer exams

Hi Sayan,
Indian Engineering Services abbreviated as IES are the civil services that meet the technical and managerial functions of the Government of India. Like most countries, the Government of India recruits its civil servants and officials on the basis of merit, the middle management positions in the bureaucracy are filled through competitive exams. Large number of candidates take these exams, competing for limited posts. IES officers are selected by the union government on the recommendations made by the Union Public Service Commission (UPSC). A combined four-stage competitive examination (comprising six tests), called the Engineering Services Examination (ESE) is conducted by the UPSC for recruitment to the Indian Engineering Services.
The nature of work performed by these bureaucrats largely depends on their engineering branch and the service or cadre they are recruited in. However, they can move to any cadre, organisation, agency, department, ministry or PSU of the Government of India. They are appointed in the posts analogous to their present one, either on deputation basis which is of a fixed tenure (at least 5 years and extensible) after which the officer returns to their parent cadre or on absorption basis where the official leaves the parent cadre and is "absorbed" permanently into the new cadre.
