**IES Syllabus PDF – Download Exam Pattern 2019-20: **Guys, we are here for you with the syllabus of the Indian Engineering Service. The exam conducted for this post is called Engineering Service Examination, this exam is conducted annually to select officers for the engineering services that meet the technical and managerial functions in various fields of engineering of the Government of India. Just like IAS, IFS, and IPS IES is also a part of central government. It is responsibility of Union Public Service Commission to recruit the eligible candidates for this post. This is amongst the most recognized job in the country which brings both money and reputation and lots and lots of responsibilities. Every year many applicants apply for the entrance exam. And it is very difficult to crack these exam and many fails to crack at once. Today we are here providing you the information related to eligible criteria for this exam.

## IES Exam Pattern & Syllabus for Officers

- The exam is of graduation level, so the candidates need to have a graduation degree.
- The syllabus is based on the five year of course in you respective field of engineering.
- As there are different field of Engineering so the syllabus is different. The different fields are: Civil, Mechanical, Electrical’s and Electronics and Telecommunication Engineering.
- There are two level of examination Preliminary and Main Exam.
- After this you will appear for the Interview Session.
- The Prelims exam is objective in nature while main is subjective.
- The medium of the exam is English.
- There will be negative marking in the exam.

### IES Preliminary Exam Syllabus
