IES(Engineering Services)

Indian Engineering Services (IES/ES) constitute of engineers that work under the government of India to manage a large segment of public sector economy which constitutes of Railroads, Public works, Power, Telecommunications, etc.
A combined competitive examination is conducted by the Union Public Services Commission (UPSC) for recruitment to the Indian Engineering Services. The Examination constitutes of a written examination followed by an interview for personality test.
What is IES Exam?
Indian Engineering Services (IES) exam (also called as Engineering Services Exam) is a premier competitive examination conducted by UPSC (Union Public Service Commission), for selecting aprox. 500-600 engineers for Government of India’s engineering organizations, such as Indian Railway Service of Engineers (IRSE), Central Engineering Service (CES), Military Engineer Services (IDSE) etc. The examination is conducted for the branches of Civil. Mechanical, Electrical & Electronics Engineering.

The popularity of this exam can be gauged from the following analysis, compiled from UPSC Annual Reports:
As you can see from above, only two to four persons per thousand who applies for IES exam, cuts the grade and becomes an IES officer. Thus the popularity of IES exam can be compared to another cream services of Government of India – IAS (Civil Sevices) exam.
This blog post is made to introduce you to IES exam: telling you when IES notification comes out, what are the eligibilities for IES exam and where you can get the IES exam application forms.
IES Exam statistics:
You can find from above IES exam statistics that close to 30% -40% people who applies for IES exam, does not appears for the IES exam. Also majority of the screening is done at the Written test - only 1.5% - 3% of those who writes the exam are called for interview. However, once you are called for the interview, chances of being finally selected is pretty good- 30%- 40%.

What were the branch-wise vacancies in IES exam from IES-2003 to IES-2006? Following analysis tells you that:

IES Exam Notification:
If you are an IES exam aspirant, you would definitely wish to know when the IES exam notification comes out. UPSC conducts IES examination every year in the 1st/2nd Saturday of June, notification for which comes out in the 1st/2nd Saturday of January month.
With above, following exam dates for IES-2010/2011 can be safely projected:

IES Exam-2010 Dates:
IES Exam-2010 Notification: 9th January, 2010 (Saturday)
IES Exam-2010 last date of form receipt: 8th February, 2010 (Monday).

IES Exam-2011 Dates:
IES Exam-2011 Notification: 8th January, 2011 (Saturday)
IES Exam-2011 last date of form receipt: 7th February, 2011 (Monday).
IES Exam-2011 Written Exam date: 4th June, 2011 (Saturday)

By following above logics, you can find the exam dates for future IES exams like IES-2012/2013 etc. Nearer this time, check this UPSC website for the IES exam notification.

IES Exam Eligibility:
Age Eligibility:
You need to be between 21 years to 30 years on the 1st August of the year of examination. For example, for IES-2010, you should be born not earlier than 2nd August, 1980 and not later than 1st August, 1989.
Age relaxations exist as per Govt. rules.

IES Exam Pattern

IES exam consists of a total 1200 mark selection process, which consists of a written test for 1000 marks and a 200 mark Interview for those shortlisted. Out of the total 1000 marks in the written test, 600 marks are for Objective test and 400 marks for Conventional test.

Plan of IES written test along with mark distribution paper-wise is given below:
IES Objective Test Papers: 600 marks
General Ability Test: 2 hrs duration: 200 marks
Electronics Engineering Paper I: 2 hrs duration: 200 marks
Electronics Engineering Paper II: 2 hrs duration: 200 marks
General Ability Test consists of:
Part A: General English
Part B: General Studies.
There are 120 questions in each of the above three papers – thus you have one minute for each question of average worth 1.67 marks.

Objective type test consists of multiple-choice questions with four options, in which you have to choose the correct option and mark the same in the answer booklet with an HB pencil, by darkening the circle (representing the correct option) completely. The answer booklet is an OMR (Optical Mark Recognition) sheet, which looks like the one below:
Negative marking:
Beware - for each wrong answer of a question, one third (0.33) of the marks assigned to that question will be deducted as penalty. Hence encircle the correct answer properly and also make wise-guesses!

IES Conventional Test Papers: 400 marks
Electronics Engineering Paper I: 3 hrs duration: 200 marks
Electronics Engineering Paper II: 3 hrs duration: 200 marks
These papers consists of descriptive (i.e. essay) type questions.
Depending on the relative performance by the IES candidates, UPSC decides the cut-off (minimum qualifying marks) in the Objective test and the papers of Conventional test is evaluated only for those above this cut-off. IES exam cut-off in the Objective test is approximately 60%.

Interview:
Interview for Personality test of selected candidates: 200marks
General (but important) instructions

  • All Question Papers must be Answered in English. Question Papers will be set in English only.
  • Candidates must write the papers themselves. They will not be allowed a scribe to write the answer for them under "any circumstances".
  • Points (upto 5%) may be deducted from the total points of a candidate if his/her handwriting is not easily legible.
  • Put in a serious and sincere effort.Marks are not allotted for mere superficial knowledge. Orderly, effective and exact expression combined with due economy of words will be rewarded.
  • SI units will be used in the papers and Candidates should use only International form of Indian numerals (i.e. 1,2,3,4,5,6 etc.) while answering question papers.
  • The Commission have discretion to fix qualifying marks in any or all the subjects of the examination.
  • The Objective Type papers will be evaluated first and evaluation of the Conventional Type papers is done only for those candidates who obtain the minimum qualifying marks in Objective types papers, as fixed by the Commission.

GATE Objective Questions Solving Tricks

Objective Solving Tricks:
Most of time students complain that they couldn’t complete their objective paper; they were struck in one or another problem and wasted a lot of time. Some says that their guess went wrong and marks were deducted due to negative marking, some could not read paper completely and missed some easy questions etc.I’ll like to stress that objective paper solving is different from subjective paper. You don’t need to study extra for objective questions but practice little bit.Your guess in solving objective can bring you in difficulty but some intelligent/educated guess can add valuable marks to your score. Most of time objective questions have some hint in the form of multiple choices for the question.Following can be used as guidelines for solving objective paper:
General Tips:
Keep the structure of GATE in mind(25 Quest 1 Mark each, 30 Quest. 2 Marks each with 4 common data questions and 4 Linked Questions).Plan your time. Allow more time for high point value questions; reserve time at the end to review your work, and for emergencies. I'll suggest following sequence, but you can keep as per your choice: 2 Marks question, Common Data Questions, Linked questions and then single mark questions.
Look the whole test over, skimming the questions and developing a general plan for your work. If any immediate thoughts come to you, jot them down in the margin Start with the section of the test that will yield the most points, but begin working with the easiest questions to gain time for the more difficult ones and to warm up. Work quickly, check your timing regularly, and adjust your speed when necessary.
Avoid reading into the questions. When you find yourself thinking along the lines of "this is too easy; there must be a trick..." mark the question and move on to another. Interpret questions literally.Mark key words in every question. To help find the key words, ask yourself WHAT, WHO, WHERE, WHEN, and HOW?
Multiple Choice Specific Tips:
Remember in GATE each question will have four choices for the answer, only one is correct and wrong answer carry 33% negative marks Read the question (without reading choices) very carefully.Mark important key words and look for special key words like not, but, except , or, nor, always, never, and only . Mark these key words.If you can think of answer before reading choices, keep it in mind before reading choices Compare with choices and select the best suited answer.

Most of times choices are made to confuse. If there are two or more options that could be the correct answer, compare them to each other to determine the differences between them.
If there is an encompassing answer choice, for example "all of the above", and you are unable to determine that there are at least two correct choices, select the encompassing choice.Make educated/intelligent guesses - eliminate options any way you can.

Multiple choices can provide direct short cut to get correct answer, especially in numerical problems. For example in the above question If you can think of answer before reading choices, keep it in mind before reading choices Compare with choices and select the best suited answer.
