Indian Engineering Services abbreviated as IES are the civil services that meet the technical and managerial functions of the Government of India. IES officers are selected by the union government on the recommendations made by the Union Public Service Commission (UPSC). A combined three-stage competitive examination (comprising five tests), called the Engineering Services Examination (ESE) is conducted by the UPSC for recruitment to the Indian Engineering Services.[1]
ESE is therefore considered as the toughest exam in India and amongst the toughest in the world due to less number of posts having a selection ratio of 0.00275 (based on 2010 statistics) and its technical nature. Because of this difficult selection procedure, IES officers carry high respect and status in society and are able to manage activities in diverse areas.
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.

PLANNING: "Give me six hours to chop down a tree and I will spend the first four sharpening the axe." - Abraham Lincoln
Make a concrete plan. Spend at least two weeks analyzing previous years question papers, type of question being asked, hotspots, syllabus, cutoff marks in all stages & others parameters. You have to be aware of how much to score to get a rank & how to score that in the worst case scenario. Ask many successful people& use their guidance & experiences.
