Quality Control & Material Testing

• What tests are conducted on cement?

• What is slump test? Purpose?

• What is cube test? When is it done?

• What is compaction and how is it achieved?

• What happens if concrete strength is low?

 Safety & Site Discipline

(Often underestimated by freshers)

• What are common site safety hazards?

• What is PPE? Name some examples

• What safety precautions are needed during:

  • Excavation

  • Scaffolding

  • Concreting

• What will you do if a worker refuses safety gear?

Construction & Site Execution Questions

• What is excavation and how is it done safely?

• What is PCC and why is it done before footing?

• Difference between footing and foundation

• Steps involved in column casting

• What checks will you do before slab concreting?

• What is curing and its importance?

Drawings & Measurements

(Very important for site engineers)

• Can you read structural drawings?

• What information is available in:

  • Plan

  • Section

  • Elevation

• How do you check dimensions on drawings vs site?

• What is BOQ?

• How do you calculate concrete quantity for a slab?

For site / construction–based entry-level civil engineering roles, interviewers mainly test fundamental knowledge, practical thinking, safety awareness, and attitude—not advanced design.

Below is a high-yield list of key interview questions, grouped by topic, with what the interviewer is really checking.

1. Basic Civil Engineering Fundamentals

(Almost guaranteed)

Concrete

• What is concrete? Its ingredients?

• What is M20 / M25 concrete?

• Difference between cement and concrete

• What is water–cement ratio and why is it important?

• What happens if excess water is added to concrete?

Steel

• Grades of reinforcement steel (Fe415, Fe500)

• Why is ribbed steel used?

• Lap length – what is it and why is it provided?

• Difference between tension and compression members
