What L&T actually looks for
Larsen & Toubro is one of India's largest engineering and construction conglomerates, with businesses spanning infrastructure, heavy engineering, defense manufacturing, power, and technology (through LTIMindtree and LTTS). Because so much of the core business is physical, building metro lines, refineries, defense equipment, and ports, interviewers for engineering roles care a lot about whether candidates actually understand fundamentals rather than just having a degree. Expect deep technical questioning on your specific discipline (civil, mechanical, electrical) grounded in real project scenarios, not abstract theory. L&T also has a strong internal culture of promoting from within and rewarding people who can manage large, complex projects with tight timelines and safety requirements, so interviewers often probe for signs of ownership and the ability to handle pressure on site. For roles in the technology arm, expect a more conventional IT services style interview, DSA, system design basics, and client communication, closer to what you'd see at other large Indian IT firms, but L&T's engineering DNA still shows up in the structured, process-driven language interviewers use.
Common questions and how to answer them
Describe a technical problem you solved on a live project or during your internship is a staple for engineering roles, L&T wants specifics: what went wrong, how you diagnosed it, what trade-offs you made under time or budget pressure. How do you approach safety and compliance when a deadline is tight? comes up because L&T operates in construction, defense, and heavy engineering where safety lapses have real consequences, a good answer never suggests cutting corners. How would you handle disagreement with a site engineer or client over design specifications? tests whether you can hold a technical position professionally while still being collaborative. For technology-arm roles, expect standard coding and system design questions plus at least one question about why you'd choose L&T's IT business over a pure product company, be ready to talk about the scale and complexity of the engineering projects the technology work supports.
How to prepare
Know your core engineering fundamentals cold, L&T interviewers (especially for site and design roles) will ask you to work through a problem on paper or a whiteboard, not just recall definitions. If you have any project or internship experience involving real construction, manufacturing, or infrastructure work, prepare two or three detailed stories using the STAR method since these get referenced heavily. Research which specific business vertical you're interviewing for, since L&T's businesses are genuinely different from each other, interview style varies a lot between the construction/infrastructure side and the technology/IT services side. For technology roles, prepare standard DSA and system design topics as you would for any large IT services company.
