Behavioral questions
Tell me about a project or internship where something went wrong on the ground. What did you do?
A good answer covers
- What went wrong and how it affected the work
- What you did yourself, and who you involved
- The outcome and what you'd do differently
Describe a time you worked in a team with a tight deadline and limited resources.
A good answer covers
- The deadline and what was in short supply
- How the team split the work and set priorities
- What you delivered, and what you learned about planning
Tell me about a time you noticed a safety risk or a quality problem and spoke up.
A good answer covers
- What you noticed and why it mattered
- How you raised it, and to whom
- What changed as a result
Tell me about something you learned outside your syllabus because a project needed it.
A good answer covers
- Why the project needed it
- How you learned it: books, software, a mentor, trial and error
- How you used it and how well you understand it now
Role and technical questions
Explain the difference between working stress design and limit state design, and why design codes use safety factors.
A good answer covers
- Working stress keeps stresses within allowable limits under service loads
- Limit state checks both collapse and serviceability using factored loads and strengths
- Safety factors cover uncertainty in loads, materials and construction
How would you check that concrete poured on site will reach its design strength?
A good answer covers
- Mix design and water-cement ratio, with slump tests for workability
- Cube samples tested at set ages
- Proper compaction and curing, and what you'd do if results came back low
Explain how a three-phase induction motor starts, and why starting current matters.
A good answer covers
- A rotating magnetic field induces current in the rotor, producing torque
- Starting current is several times the running current
- Starting methods such as star-delta, soft starters or drives, and why they're used
Walk me through how you'd choose a material for a pressure vessel or a heavy fabricated part.
A good answer covers
- Operating conditions: pressure, temperature, corrosion, cyclic loading
- Properties: strength, toughness, weldability, availability and cost
- The design code that applies, and the testing and inspection needed
A construction project is running two weeks behind schedule. How would you recover time without compromising safety?
A good answer covers
- Finding which activities on the critical path caused the delay
- Options: more crews or shifts, re-sequencing, prefabrication
- Holding safety and quality checks, and keeping the client informed
Explain the critical path method and how you'd use it to plan a project.
A good answer covers
- Listing activities, their durations and dependencies
- The critical path: the longest chain, where any delay delays the project
- Using float to set priorities and update the plan as work progresses
Walk me through your final-year project: the problem, your part in it, and what you'd do differently.
A good answer covers
- The problem and why it mattered
- Your own contribution, including calculations or design choices
- Results, limits and what you'd change with more time
How would you estimate the quantity of steel needed for a simple building frame? Talk me through your approach.
A good answer covers
- Working from drawings: members, sizes and reinforcement details
- Rules of thumb for a first estimate, then a proper bar bending schedule
- Allowing for laps, wastage and checking against similar projects
Why Larsen & Toubro? Fit and HR questions
Why L&T, and which of its businesses would you like to work in?
A good answer covers
- Something specific about L&T's work that interests you
- One business you've read about and why it suits your branch
- What you want to learn in your first years
Are you willing to work at project sites or plants anywhere in India, including remote locations?
A good answer covers
- An honest answer, with any genuine limits stated
- Why site experience matters for an engineer
- Any time you've lived or worked away from home
Where do you see yourself five years after joining as a trainee?
A good answer covers
- A realistic path: deeper technical skill, then more responsibility
- Skills or certifications you'd build

Tips
- Revise your core subjects deeply; L&T's careers site says it looks for conceptual clarity, not just marks.
- Know your final-year project and internships in detail, including the calculations and what didn't work.
- Read about L&T's businesses on its website and be ready to say which one interests you and why.
- Give an honest answer on site postings; projects can be far from cities, and interviewers want to see you've thought it through.
- Expect a health examination before joining, which L&T's careers site notes for GETs.
Practise it out loud
A mock interview asks the way Larsen & Toubro's interviewers are known to, follows up on your answers and gives you a report. The warm-up is free, needs no account and checks five of these questions as you answer.
