This article deals with problem on “How to prepare for ESE Electronics and Telecommunication ” ESE that is Engineering Service examination was earlier known as IES (Indian engineering services) is conducted by UPSC which also conduct exams like civil services , CDS, NDA. ESE exams are for engineers and are conducted for foour streams.
- Civil Engineering
- Mechanical engineering
- Electrical Engineering
- Electronics & Telecommunication Engineering
Exam constitutes of 3 stages
Each stage has 2 papers and students have to clear each stage to appear in exam at next stage.
Stage 1 of ESE exam for Electronic and Telecommunication Engineering
General studies and Engineering Aptitude: This paper is common for all four streams of ESE exam which is of 2 hours and 200 Marks.
