Official Railway Junior Engineer (JE) Syllabus for Civil, Mechanical, Electrical & Electronics Engineering. Download topic-wise CBT-1 & CBT-2 Syllabus in PDF.
RRB JE Selection Process
The recruitment process for Junior Engineer (JE), DMS, and CMA posts involves four stages:
1st Stage CBT: Screening test (100 Marks). Marks are normalized but not added to the final merit.
2nd Stage CBT: Main technical exam (150 Marks). Final merit is based on this stage.
Document Verification (DV): Verification of B.Tech/Diploma certificates.
Medical Examination (ME): JE posts generally require A-3, B-1, or B-2 medical standards.
