Indian Engineering Services Examination is conducted for recruitment in different engineering services in various Government Departments . Indian Engineering Services shortened as IES are the civil services that meet up the managerial and technical functions of the Government of India. Like the other countries, the Government of India selects its civil servants on the foundation of merit based on the supervision positions in the officialdom. Large number of candidates appear for these exams, competing for limited posts. It’s a joint four-stage competitive examination conducted by the Union Public Service commission UPSC for enrollment to the Indian Engineering Services.IES is considered to be the most adored careers for the engineering graduates in India and also one of the toughest exam conducted as less number of post are available.
Mechanical engineering is among the most diversified of the time-honored engineering disciplines. Mechanical branch is said to be one of the oldest branch in the field of engineering. It is sometime referred to as ‘mother’ of engineering also. Another marking feature of this branch is that it has diverse and broad study base .Mechanical engineers has to deal with mechanics , robotics, thermodynamics ,fluid mechanism ,kinematics and many other s concepts also mechanical engineers develop various engines ,heating and cooling system and other machinery .Mechanical engineers are not only responsible for designing new machines but also are accountable for testing ,manufacturing and maintaining the systems.
Details about the Examination:
The examination take place in two parts mainly :
(i)Written Tests :
It consists of five papers each carries 200 marks. General Ability is the first Paper consisting of objective type questions from General English and General Studies which includes knowledge of current events, Indian History and Geography. The rest four papers are related to the applicable engineering discipline. In the next section which is definite to the applicable engineering discipline will have objective type questions for first two papers and subjective type questions for the rest two papers . So Written test is total of 1000 marks.
Personality test carries 200 marks and the candidates who qualify the written tests will be called for personality test.
