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 organisation, agency, department, ministry or PSU of the Government of India on deputation. They are appointed to 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
