The SSC conducts SSC JE examination to recruit students for several junior engineer posts such as Electrical, Civil, Mechanical, contract Posts, and Quantity Surveying, etc. The students who clear SSC JE paper 1 are shortlisted for SSC JE paper 2. To get selected, one needs to focus on the SSC JE Paper 2 Important Topics. 

• As per a recent notification released by SSC for Junior Engineer, a total number of of 1601 Junior Engineer posts will be filled through SSC JE recruitment.
• The SSC JE Paper 2 Important Topics has three main segments, like Civil & Structural Engineering, Electrical Engineering and Mechanical Engineering.
• SSC JE Civil & Structural covers topics like Steel Design, RCC Design, Surveying, Building Materials, etc. 
• SSC JE Electrical Engineering covers topics like measurement and Measuring Instruments, Electrical Machines, etc. 
• SSC JE Mechanical Engineering like Production Engineering and Thermal Engineering etc. 
• Go through the SSC JE Paper 2 Exam Analysis to know which questions were asked in the previous year Paper 2 Exam and what was the difficulty level of the paper.

The SSC JE exam will be conducted in offline mode. It is a descriptive paper where all subjects should be answered in a descriptive way. However, there is no negative marking. The paper is conducted in three steps - part A (Civil & Structural), part B (Electrical) and part C (Mechanical). The candidates will have a duration of 2 hours to attempt 300 marks.
