Engineering Services Examination 2020 - IES Syllabus for ETE

Last Modified: 12 May 2024

Indian Engineering Services (IES), also known as Engineering Services Examination (ESE), is conducted annually by the Union Public Service Commission (UPSC). The exam comprises of a written examination and interview. The recruitment is done to the services under different categories - Civil Engineering, Mechanical Engineering, Electrical Engineering, and Electronics and Telecommunication Engineering. Candidates are required to apply for different posts as per their qualification. The article here is covering the IES Syllabus for ETE. Interested candidates must check the syllabus carefully and prepare for the exam accordingly.
