Mechanical Exam

IES, i.e. Indian Engineering Service, is the dream of every engineer in India. IES officers are selected by the union government on the recommendations made by the Union Public Service Commission (UPSC). IES officers 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 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. ESE is considered as the toughest exam in India and amongst the toughest in the world due to less number of posts and its technical nature.

ESE 2016 Exam Pattern

ESE is a four-stage competitive examination (comprising six tests). The entire examination is divided into two parts:

Written Examination - 1000 Marks

Interview - 200 Marks

Total - 1200 Marks

There are objective as well as conventional (descriptive) papers. One paper (Paper I) for GA (General Ability) is part of the assessment system apart from the engineering subject of the candidate. The entire technical subject is divided into four papers (Papers II, III, IV & V). There is a penalty (negative marking) for wrong answers marked by the candidate in the objective type papers. There is a three-day schedule of the written examination, comprising all five written examinations.

Scheme of Examination

Paper I (Objective type)

General Ability Test (Part A: General English) (Part B: General Studies)

200 Marks

Papers II & III (Objective type)

Civil Engineering / Mechanical Engineering / Electrical Engineering / Electronics & Telecommunication Engineering

200 Marks for each paper

Papers IV & V (Conventional type)

Civil Engineering / Mechanical Engineering / Electrical Engineering / Electronics & Telecommunication Engineering

200 Marks for each paper

Total marks for written examination

1000 Marks

Interview

Personality Test

200 Marks

First stage

The first day is allocated for the General Ability (GA) paper. This exam is of 2 hours duration. On the first day there is just one exam. This exam consists of General English and General Studies. Paper is maximum of 200 marks.

Second stage

The second day is allocated for the Objective Technical Papers (II & III). There is one objective exam for each paper separately and each being of 2 hours in duration. Each paper is maximum of 200 marks.

Third stage

The third day is allocated for the Conventional Technical Papers (IV & V). There is one subjective exam for each paper separately and each being of 3 hours in duration. Each Paper is maximum of 200 marks.

The conventional answer sheets of a candidate are evaluated only when he / she qualifies the objective examination.

Interview (Fourth Stage)

This is the fourth and final stage; candidates who qualify the written exam are called for the interview. Interview carries 200 marks. Officially called "Personality Test", the object of the interview is to assess the personal suitability of the candidate for a career in public service by a Board of competent and unbiased observers. The test is intended to judge the mental calibre of a candidate. In broad terms this is really an assessment of not only his intellectual qualities but also social traits and his interest in current affairs. Some of the qualities to be judged are mental alertness, critical powers of assimilation, clear and logical exposition, balance of judgement, variety and depth of interest, ability for social cohesion and leadership, intellectual and moral integrity.

The technique of the interview is not that of a strict cross-examination but of a natural, though directed and purposive conversation which is intended to reveal the mental qualities of the candidate.

The interview test is not intended to be a test either of the specialized or general knowledge of the candidates which has been already tested through their written papers. Candidates are expected to have taken an intelligent interest not only in their special subjects of academic study but also in the events which are happening around them both within and outside their own state or country as well as in modern currents of thought and in new discoveries which should rouse the curiosity of well-educated youth.

These four stages ensure that the candidates selected, are best suited to handle the responsibilities which will be entrusted to them. The selected candidates then undergo training at the academies / institutes of their respective cadres that makes them acquainted with the area of work, the cadre / service is engaged in.

ESE 2016/ IES 2016 Preparation

ESE written exam consists of both objective and conventional type questions hence theory, conceptual knowledge and problem solving techniques are equally important.
Good writing skills, excellent presentation, subjective theory, explanations, derivations, diagrams and equations will fetch you good marks in conventional or subjective paper.
Be aware of exam pattern like how many technical & non-technical questions are asked, negative marks, weightage, exam duration and marks per question. Always make a habit of referring previous year question papers.
Prefer Reference books for derivations, equations, conceptual thinking, theory etc.
Short Cut Techniques

Use short techniques for numerical solving instead of traditional approach.

Reading news paper, watching morning bulletin, surfing websites will help the candidates to prepare and score better in the General ability paper carrying 200 marks.
Do not neglect General Ability part as this section is scoring and also plays an important role in personal interview.
Practice previous year question papers and analyze the weak topics and concentrate more on those topics. Always try to solve the papers in given time to obtain an idea that how many questions you are able to solve in given time limits.
Intense knowledge of the subjects, strong basics, and clear concepts helps in better understanding of the subjects and prove to be instrumental in getting good scores.
Personal Interview

Sound technical knowledge, Positive attitude, Body language, Good communication skills, knowledge about current affairs plays an important role to clear personal interviews. Candidates should be prepared for the questions about their strengths and weaknesses.
