Introduction to Civil Engineering Questions for Interview
Civil Engineering questions for Interview will consist of Interview questions that are quite important for grabbing any Job opportunity. Civil Engineering is a branch that deals with designing, construction, and maintenance of a physical and nature-built environment which includes roads, dams, canals, airports, stations, pipelines, buildings, etc. Civil engineering is one of the oldest built engineering disciplines. It is one of the exciting professions to take over as at the end of the day, you will be able to see the result of work done. Let us see some of the Top 20 important questions to have a quick understanding of the Civil Engineering discipline.
Part 1 – Civil Engineering Questions for Interview (Basic)
This first part covers basic Interview Questions and Answers.
Q1. What is the difference between a flat slab, a one-way slab, and a two-way slab?
Answer:
A flat slab is supported on columns i.e., it does not have beams.
One way slab has Ratio(Longer Span/ Shorter Span) > 2.
Two-way slab has Ratio(Longer Span/ Shorter Span) <=2.
Q2. List out types of Slump
Answer:
There are 4 types of Slump:
- True Slump: The concrete mass that is slumped evenly around without any disintegration is a true slump.
- Collapse Slump: When a sample collapses due to the addition of excess water is known as a collapse slump.
- Shear Slump: This type of slump is found in the lean concrete mix. When half of the concrete mass slides down on the other, that is called a Shear slump.
- Zero Slump: For dry or stiff mixes, this slump does not allow any changes after removing the slump cone.
Q3. What is Flashing?
Answer:
It is an extended construction that seals and protects joints in the building for water penetration. Flashing is installed at walls, intersection roofs, and parapets.
Q4. Define demising walls?
Answer:
It is used for the boundary that separates your land with neighbor’s land.
Q5. What are wooden shingles?
Answer:
These wooden shingles are rectangular in shape, similar to slats that are nailed to the exterior surface. Shingling is a traditional method for weatherproofing.
Part 2 – Civil engineering questions for interview (Advanced)
Let us now have a look at the advanced Interview Questions and Answers.
Q6. What are all the reinforcements used in process of prestressing?
Answer:
We have 3 primary reinforcements used in prestressing process.
- Spalling Reinforcements

Q7. What does Honeycomb mean in concrete?
Answer:
Honeycomb is also known as Air Pocket. It is the air voids found in concrete that are usually formed during concrete casting.
Q8. What are the uses of Groynes?
Answer:
Groynes prevent or slow down erosion and stop the longshore drift. It can cause bad knock-on effects somewhere nearby areas.
Q9. What is the purpose of having gaps in the road on the bridge?
Answer:
Gaps in the road allow concrete to expand and contract with changes in temperature without causing any damages or deformation on roads.
Q10. How is the quality of cement checked on-site?
Answer:
Various quality checks are done, but the main checks include,
Date of Manufacturing: As the cement, strength decreases with age.
Float Test: Good cement is considered not to float if thrown in water.
Color: It should of Grey color with a light greenish shade included.
On touching or placing your hand inside cement, it needs to be cold.
Q11. What is the Slope of the Staircase and crack length in the Slab?
Answer:
With respect to IS 456, the slope of stairs should be between 25 degrees to 40 degrees.
The crack length of the Slab is 0.42D where D refers to the depth of the Slab Top Cover Bottom Cover.
Q12. Which is the World’s Largest Concrete Dam?
Answer:
World Largest Concrete Dam is The Grand Coulee Dam.
Q13. What are the Types of Roofs present?
Answer:
Types of Roofs are,

- Dutch Gable Roof
- Half Hipped Roof
- Gambrel Roof
- Gull Wind Roof
- Monitor Roof
- Skillion Roof
- Sawtooth Roof
- Mansard Roof, etc.

Q15. What is the Critical Path Method?
Answer:
CPM, Critical Path Method is the method of representing respective tasks and activities involved in construction through symbolic diagrams.
Q16. List out different types of Foundations?
Answer:
We have three main Foundations,
- Basement: It is the one constructed at first, and then the building is constructed on top of it
- Crawl Space: It is a raised foundation and is built above ground, to allow enough space to crawl underneath it.
- Slab: Here, concrete is directly poured into a pit made in the ground.
