10 Interview questions

A Demonstrator was asked 8mo ago
Q. What is the significance of the water-cement ratio in concrete mix design?
Ans. 

Water-cement ratio in concrete mix design affects the strength, durability, workability, and permeability of the concrete.

  • Water-cement ratio determines the amount of water needed to fully hydrate the cement in the concrete mix.

  • A lower water-cement ratio leads to higher strength and durability of the concrete.

  • An excessive water-cement ratio can result in lower strength, increased permeability, and reduced durabilit...

Q. What is the difference between a one-way slab and a two-way slab in terms of design and load distribution?
Ans. 

One-way slabs distribute load primarily in one direction, while two-way slabs distribute load in two directions.

  • One-way slabs are designed to span in only one direction, typically supported on two opposite sides. They distribute load primarily in one direction.

  • Two-way slabs are designed to span in two directions, supported on all four sides. They distribute load in both directions, providing more balanced load dis...

A Demonstrator was asked 8mo ago
Q. What are the different types of retaining walls and their applications in civil engineering projects?
Ans. 

Different types of retaining walls include gravity walls, cantilever walls, sheet pile walls, and anchored walls.

  • Gravity walls rely on their weight to resist pressure from soil behind them.

  • Cantilever walls have a base slab and a stem that leans back into the retained soil.

  • Sheet pile walls are made of steel, vinyl, or wood planks that are driven into the ground.

  • Anchored walls use cables or other stays anchored in t...

A Demonstrator was asked 8mo ago
Q. What are the primary causes of cracks in concrete structures, and how can they be prevented?
Ans. 

Primary causes of cracks in concrete structures include shrinkage, thermal changes, overloading, and poor construction practices.

  • Shrinkage: Concrete shrinks as it cures, leading to cracks if not properly controlled.

  • Thermal changes: Temperature fluctuations can cause concrete to expand and contract, leading to cracks.

  • Overloading: Excessive weight or stress on a concrete structure can cause it to crack.

  • Poor construc...

Q. Explain the working principle of a cantilever beam and where it is typically used in construction.
Ans. 

A cantilever beam is a structural element supported at only one end, with the other end free to deflect. It is commonly used in construction for balconies, bridges, and canopies.

  • A cantilever beam is a structural element that is fixed at one end and free to deflect at the other end

A Demonstrator was asked 8mo ago
Q. Explain the concept of moment of inertia and its significance in structural engineering.
Ans. 

Moment of inertia is a measure of an object's resistance to changes in its rotation. It is crucial in structural engineering for analyzing the stiffness and stability of structures.

  • Moment of inertia quantifies how mass is distributed around an axis of rotation

  • It plays a key role in determining the bending and deflection of beams

  • Higher moment of inertia indicates greater resistance to bending and deformation

  • Used in...

A Demonstrator was asked 8mo ago
Q. What is the difference between reinforced concrete and prestressed concrete?
Ans. 

Reinforced concrete has steel bars embedded within the concrete to provide additional strength, while prestressed concrete has tensioned steel tendons to actively counteract the concrete's natural tendency to crack under load.

  • Reinforced concrete uses passive reinforcement in the form of steel bars or mesh, while prestressed concrete uses active reinforcement in the form of tensioned steel tendons.

  • In reinforced con...

A Demonstrator was asked 8mo ago
Q. How do you calculate the quantity of cement, sand, and aggregates required for 1 cubic meter of concrete?
Ans. 

The quantity of cement, sand, and aggregates for 1 cubic meter of concrete can be calculated by using the mix design ratios.

  • Calculate the total volume of concrete needed (1 cubic meter).

  • Determine the mix design ratios for the concrete (e.g. 1:2:4 for cement:sand:aggregates).

  • Calculate the quantity of each material by multiplying the volume by the ratio (e.g. for 1:2:4, 1/7 cubic meters of cement, 2/7 cubic meters o...

A Demonstrator was asked 8mo ago
Q. Describe the process of a slump test and its importance in concrete work.
Ans. 

Slump test is a method to measure the consistency of concrete mix before it sets.

  • Process involves filling a mold with concrete, then removing the mold and measuring the amount of slump or settlement

  • Importance lies in ensuring the concrete mix has the right consistency for proper construction

  • Results of the test help determine if more water or additives are needed to achieve desired strength and workability

Interview Tips & Stories

Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.
