Engineering Services Examination (ESE) is one of the most prestigious examinations conducted in India by UPSC. It gives an opportunity to engineers to work under the government of India and designated as Class – 1 officer in public sectors such as Indian Railways, Power, Telecommunications, Central Water Engineering, Defence service of Engineers, Central Engineering Service, etc. The ESE examination paper is conducted for four branches: Mechanical Engineering, Electronics & Telecommunication Engineering, Electrical Engineering, and Civil Engineering.
Here we are providing all important technical questions which were asked in previous ESE interviews and will be useful for ESE interview.
