RRB JE (Junior Engineer) Exam Guide: Eligibility, CBT-1, CBT-2 and DV

What RRB JE is

RRB Junior Engineer (JE) recruitment is the main railway route for diploma- and degree-holding engineers into technical posts in Indian Railways. A single JE notification typically covers Junior Engineer and several allied technical posts across engineering departments, and candidates apply based on their engineering discipline.

What makes JE distinct is its 'exam group' system: your eligible engineering qualification maps you to a specific exam group, and the technical portion of the second-stage test is drawn from that group's subjects. This is different from clerical (NTPC) or Level-1 (Group D) railway recruitment, and it is aimed squarely at engineering graduates and diploma holders. The exact posts, departments and exam-group mapping are set out in the official notification.

Who conducts it

JE recruitment is conducted by the Railway Recruitment Boards (RRBs), coordinated by the Railway Recruitment Control Board (RRCB) under the Ministry of Railways. You apply to a specific RRB region and appear in centralised computer-based tests.

Official notifications, application links, exam-group details, admit cards, answer keys and results are published on the official RRB channels — the RRCB site, the unified RRB portal and the regional RRB websites. Treat those official pages as the single source of truth for every rule described here.

Eligibility (verify specifics officially)

Eligibility is qualification-based. Broadly, you need a diploma or a degree in a relevant engineering discipline; the notification lists the acceptable qualifications and maps each one to the exam group and posts you can apply for. Some allied posts have their own specific science or engineering qualification requirements.

Age limits, category-wise relaxation, application fees and the nationality requirement are specified officially; recruitment is open to Indian citizens as per the notification. Because the eligible-qualification list and exam-group mapping are detailed and can change, read the notification carefully to confirm which posts and groups your qualification makes you eligible for before applying.

• Diploma or degree in a relevant engineering discipline — mapped to exam groups in the notification
• Some allied posts have specific science/engineering qualification requirements
• Age limit and category relaxation: stated officially only
• Application fee, refund rules and nationality: per the notification

Stages and exam pattern

JE selection runs through two computer-based tests and verification stages. CBT-1 is a screening test — objective, covering Mathematics, General Intelligence & Reasoning, General Awareness and General Science — and its score is used only to shortlist candidates for CBT-2, not for the final merit.

CBT-2 is the decisive stage. It includes a general section along with a technical section drawn from the subjects of your exam group (your engineering discipline), so your technical depth matters most here. Candidates shortlisted on CBT-2 marks are called for Document Verification, followed by a Medical Examination. There is negative marking in the CBTs. The exact number of questions, marks, durations, section splits, the technical-section subjects per exam group, and the qualifying standards are all specified in the official notification.

• CBT-1: screening/qualifying — objective, general subjects
• CBT-2: counts toward merit — general section plus a technical section from your exam group
• Negative marking applies in the CBTs
• Document Verification and a Medical Examination follow CBT-2

How to prepare

The heart of JE preparation is your engineering discipline. Because CBT-2's technical section is drawn from your exam group, revise your core diploma/degree subjects thoroughly and practise applying them under exam conditions. For CBT-1 and the general section of CBT-2, keep your quantitative aptitude, reasoning and general awareness sharp so you clear the screening stage comfortably.

Use timed full-length mocks to build pace and to control negative marking, and analyse your mistakes so the technical section — where marks are decisive — is where you are strongest. No preparation source can guarantee selection; the merit list is competitive and finalised only by the RRBs. Focus on solid technical command plus accurate, timed practice.

• Deep revision of your engineering exam-group subjects (the decisive technical section)
• Keep quantitative aptitude, reasoning and general awareness sharp for CBT-1 and the general section
• Timed mocks to build pace and manage negative marking

What to verify on the official notification

JE specifics — eligible qualifications, the exam-group mapping, vacancies, age, fees, and the CBT pattern — are set per recruitment cycle. The current official notification for your RRB is the only reliable source.

Rules change frequently — verify which qualifications and exam groups you are eligible for, the vacancy count, age limit and relaxation, fees, the CBT-1/CBT-2 pattern, negative marking and qualifying standards, and the schedule on the official RRB channels before acting. Do not rely on unofficial documents for any hard fact.

• Vacancies, age limit, category relaxation and fees
• CBT-1 / CBT-2 pattern, technical-section subjects and negative marking
