The SSC Junior Engineer (JE) exam is one of the most sought-after entry points into central government service for engineering graduates and diploma holders. This guide covers everything you need for the 2026 cycle — exam pattern, complete branch-wise syllabus, topic weightage, salary, and a realistic preparation roadmap.
What is SSC JE?
SSC JE is conducted by the Staff Selection Commission to recruit Junior Engineers (Group B, Non-Gazetted) across central government departments. Selected candidates work in organizations like CPWD, MES, CWC, BRO, and more — depending on their branch and preference.

Exam Pattern
The selection process has two stages, both conducted in CBT (Computer-Based Test) mode.
Paper 1 — Qualifying + Merit
| Section | Questions | Marks | Negative Marking |
|---|---|---|---|
| General Intelligence & Reasoning | 50 | 50 | 0.25 |
| General Awareness | 50 | 50 | 0.25 |
| Technical (Civil / Electrical / Mechanical) | 100 | 100 | 0.25 |
| Total | 200 | 200 |
Duration: 2 hours
Paper 2 — Technical Depth
| Subject | Questions | Marks | Negative Marking |
|---|---|---|---|
| Branch-specific Technical | 100 | 300 | 1.0 (1/3rd) |
Duration: 2 hours
Important: Both papers contribute to the final merit list. Paper 2 carries 3 marks per question with a strict 1-mark penalty — accuracy matters more than speed here.

Frequently Asked Questions
Is negative marking the same for both papers?
No. Paper 1 deducts 0.25 marks per wrong answer. Paper 2 deducts 1.0 mark (one-third of 3 marks) per wrong answer — so accuracy is critical in Paper 2.
Can final year students apply?
Yes, provisionally. You must have your degree or diploma certificate by the "crucial date" mentioned in the official notification. Missing this deadline leads to disqualification at Document Verification.
Can diploma holders apply?
Yes, but check department-specific rules. BRO and MES require 2 years of post-diploma work experience. CPWD, CWC, and NTRO accept diplomas without experience.
Are calculators allowed?
Paper 1 — no calculators. Paper 2 — an on-screen virtual scientific calculator is provided. Some centers may allow non-programmable personal calculators; confirm from the official notification.
Is GATE score valid for SSC JE?
No. SSC JE has its own exam. GATE scores are used separately for PSU recruitments like BHEL, ONGC, and IOCL.
What is the difference between SSC JE Civil and Mechanical structural syllabus?
Civil focuses on static infrastructure — Theory of Structures, Concrete Technology, and Steel Design. Mechanical focuses on moving parts — Machine Design, Theory of Machines, gears, and flywheels.
