NMDC exams for non-executive roles like field attendants, maintenance assistants and HEMM positions usually involve a written test (think multiple choice questions) and sometimes a physical ability test or skill test depending on the job and Positions. The written test tests your general intelligence, number-counting skills, basics of English and, for technical roles, your knowledge of specific trades. Here’s a human-friendly description of what you’ll need to study for each position.

1. Field Attendant: The Ground-Level Hustle
Field attendant is a non-technical role, often requiring only 8th or 10th grade pass. It is all about testing your basic knowledge and practical readiness for fieldwork. Here is what you may face:
Written Test Breakdown:
- General Knowledge (20-30 marks): This is like a quick quiz on the world around you!
- What’s happening in the news (national and global events)?
- A bit of Indian history (freedom fighters, key events), geography (rivers, states), and culture.
- Basic science (think 8th-grade stuff like plants, animals, or simple physics).
- Who won what in sports or awards? Any big days or events to know?
- Numerical Ability (20-25 marks): Dust off your calculator (or your brain’s math mode)!
- Simple math: addition, subtraction, multiplication, division.
- Percentages (like discounts at a store), ratios, and proportions.
- Averages, simple interest, and time-and-work problems (e.g., how long to finish a task?).
- Number patterns and basic fractions.
- General English (15-20 marks): No Shakespeare here, just straightforward English.
- Basic grammar: tenses, prepositions, articles (a, an, the).
- Vocabulary: synonyms (big = large), antonyms (hot ≠ cold).
- Short reading passages to test comprehension.
- Fixing sentences or filling in blanks.
- Reasoning (15-20 marks): Think of this as a fun brain teaser!
- Spotting patterns in numbers or letters.
- Directions (e.g., “Turn left, then right, where are you?”).
- Simple puzzles, analogies (cat is to kitten as dog is to…?), or coding-decoding.
Physical Ability Test (if required):
Some notifications may ask you to prove that you are physically fit for fieldwork – such as running short distances, lifting moderate weights or showing that you can handle outdoor chores. Check the official ad for details!
2. Maintenance Assistant (Mechanical/Electrical): The Technical Wizard
Maintenance Assistants are the folks keeping machines humming, so you’ll need ITI or diploma-level knowledge in either Mechanical or Electrical trades. The exam tests your technical chops alongside general skills.
Written Test Breakdown:
- General Knowledge (20-25 marks): Same as Field Attendant—stay updated on current events, Indian history, geography, and basic science.
- Numerical Ability (20-25 marks): Same math basics—percentages, ratios, averages, and time-and-work problems.
- General English (15-20 marks): Same as above—grammar, vocab, and short comprehension passages.
- Reasoning (15-20 marks): Same brain teasers—series, analogies, coding-decoding, and directions.
- Trade-Specific Knowledge (30-40 marks): This is where your ITI training shines!
- For Mechanical:
- Basics of machines: How do gears, levers, or engines work?
- Workshop skills: Welding, fitting, or machining techniques.
- Tools you’d use (spanners, drills, etc.) and how to maintain them.
- Reading engineering drawings (like blueprints).
- Hydraulics and pneumatics (think fluid or air-powered systems).
- Fixing and maintaining mechanical equipment.
- For Electrical:
- Electrical basics: Circuits, voltage, current, and resistance.
- Working with motors, transformers, or generators.
- Wiring setups and safety rules (no shocks, please!).
- Measuring tools (multimeters, anyone?).
- Power distribution and basic troubleshooting.
3. HEMM (Heavy Earth Moving Machinery): The Big Machine Boss
HEMM posts are for operating heavy-duty machines like excavators, bulldozers, or dumpers. You’ll likely need an ITI qualification or a heavy vehicle license, and the exam tests your machinery know-how.
Written Test Breakdown:
- General Knowledge (20-25 marks): Same as above—current affairs, history, geography, and basic science.
- Numerical Ability (20-25 marks): Same math—percentages, ratios, and simple calculations.
- General English (15-20 marks): Same English basics—grammar, vocab, and comprehension.
- Reasoning (15-20 marks): Same puzzles and logic—series, directions, and coding.
- Trade-Specific Knowledge (30-40 marks): This is all about mastering those big machines!
- Types of HEMM: Excavators, loaders, dozers, and their functions.
- Operating heavy machinery safely (no rogue bulldozers!).
- Basic maintenance: Checking oil, greasing parts, or spotting issues.
- Diesel engines and hydraulic systems (the heart of HEMM).
- Safety rules for heavy vehicles and worksites.
- Traffic rules for driving heavy machinery (if applicable).
