Trainees routinely work with state-of-the-art PLC/SCADA automation, heavy structural steel fabrication, HV/EHV substation commissioning, tunnelling TBMs, and advanced quality assurance protocols. The compensation for 2026 GET inductees ranges between ₹4-6 LPA, with location-based allowances, health coverage, transport, and housing subsidies substantially enhancing the total cost-to-company (CTC). For candidates aiming to build long-term careers in core engineering, infrastructure, and heavy manufacturing, L&T remains an uncompromising benchmark of professional credibility.

Exam Pattern 2026

L&T’s written assessment for the 2026 GET batch is conducted via a proctored online platform featuring sectional timing, negative marking in select segments, and a strong emphasis on engineering fundamentals alongside analytical capability. The test pattern is engineered to filter candidates with both conceptual clarity and practical problem-solving speed.

Key Testing Guidelines:

• Sectional timing is enforced; switching between sections is not permitted.
• Negative marking of 0.25 marks per incorrect answer applies to Quantitative and Core Technical sections.
• Core Technical questions align with GATE-level conceptual depth but emphasize industry application (e.g., thermodynamics cycles, RCC detailing, motor selection, PLC troubleshooting).
• Candidates scoring above 60th percentile typically receive technical interview invites.

Technical Questions

Below are 12 domain-relevant MCQs reflecting L&T’s core engineering assessment style. Each question is mapped to Mechanical, Civil, Electrical, or Electronics streams.

1. Mechanical: In a reciprocating steam engine, the ratio of work done on the piston during expansion to the work done by the piston during compression in a cycle is known as: a) Compression ratio b) Expansion ratio c) Diagram factor d) Mean effective pressure Answer: b) Expansion ratio
   Explanation: The expansion ratio defines the volume ratio of the cylinder at the end of expansion to the volume at the beginning. It directly influences thermal efficiency and diagram work output.

2. Mechanical: The failure of a ductile material under static loading is primarily predicted by: a) Maximum Principal Stress Theory b) Maximum Shear Stress Theory (Tresca) c) Mohr’s Circle d) Fatigue Strength Criterion Answer: b) Maximum Shear Stress Theory (Tresca)
   Explanation: Tresca准则 (Tresca theory) states yielding begins when maximum shear stress reaches half of yield strength. It is widely used for ductile metals in structural/machinery design.

3. Civil: In limit state design of RCC beams, the balanced failure condition occurs when: a) Concrete reaches ultimate strain before steel yields b) Steel reaches yield strain before concrete crushes c) Both concrete and steel reach their respective ultimate strains simultaneously d) Shear failure precedes flexural failure Answer: c) Both concrete and steel reach their respective ultimate strains simultaneously
   Explanation: Balanced section ensures optimal utilization of material strength per IS 456:2000, with concrete strain at 0.0035 and steel at 0.002+ fy/1.15Es.

4. Civil: The compaction of cohesive soils for subgrade construction is best achieved using: a) Vibratory roller b) Pneumatic tire roller c) Sheep foot roller d) Smooth wheel roller Answer: c) Sheep foot roller
   Explanation: Sheep foot rollers provide kneading action essential for breaking clay lumps and achieving uniform density in high-cohesion, low-permeability soils.

5. Electrical: In a 3-phase induction motor, the torque is directly proportional to: a) Stator voltage b) Square of stator voltage c) Supply frequency d) Rotor resistance at standstill Answer: b) Square of stator voltage
   Explanation: T ∝ V², hence voltage fluctuations severely impact motor torque and efficiency. This is critical in site equipment selection at L&T construction sites.

6. Electrical: The primary purpose of a Buchholz relay in a power transformer is: a) Overcurrent protection b) Earth fault detection c) Internal fault detection via gas accumulation d) Voltage regulation Answer: c) Internal fault detection via gas accumulation
   Explanation: Thermal degradation or arcing decomposes oil into gases. Buchholz relays detect minor (alarm) and major (trip) internal faults in oil-immersed transformers.

7. Electronics & Instrumentation: Which transducer converts pressure into a change in electrical resistance? a) Capacitive transducer b) Strain gauge c) LVDT d) Piezoelectric crystal Answer: b) Strain gauge
   Explanation: Strain gauges operate on the piezoresistive effect. Resistance changes proportionally to mechanical deformation, widely used in load cells and pressure transmitters.

    Explanation: At no load, rotor speed approaches synchronous speed. Small slip is required to induce rotor current for core loss compensation and windage.

12. Electronics & Instrumentation: The bandwidth of a control system is defined as: a) Difference between maximum and minimum supply voltage b) Frequency range where gain remains within 3 dB of DC value c) Sampling rate of a digital signal d) Maximum allowable error before saturation Answer: b) Frequency range where gain remains within 3 dB of DC value
    Explanation: Bandwidth dictates response speed and noise rejection. Higher bandwidth improves transient response but increases susceptibility to high-frequency disturbances.

Quantitative Aptitude Questions

L&T’s quant section tests speed, accuracy, and application-based problem solving. Below are 8 representative problems with detailed solutions.

1. Question: A contractor estimates that 18 workers can complete a site grading job in 24 days. After 8 days, heavy rains halt work for 3 days. To complete the remaining work on schedule, how many additional workers must be hired?
   Solution:
   Total work = 18 × 24 = 432 man-days
   Work done in 8 days = 18 × 8 = 144 man-days
   Remaining work = 432 − 144 = 288 man-days
   Days left after rain delay = 24 − 8 − 3 = 13 days
   Required workers = 288 ÷ 13 ≈ 22.15 → 23 workers needed
   Additional workers = 23 − 18 = 5 workers

2. Question: Two trains of length 150 m and 200 m cross each other in 18 seconds when moving in opposite directions. If the faster train’s speed is 54 km/h, find the slower train’s speed.
   Solution:
   Relative speed = (Total distance)/(Time) = 350/18 = 19.44 m/s
   Convert to km/h: 19.44 × 3.6 = 70 km/h
   Relative speed (opposite) = V1 + V2 → 54 + V2 = 70 → V2 = 16 km/h

3. Question: A mixture contains 40% solvent by volume. After evaporating 20 liters of solvent, the concentration becomes 25%. Find the initial volume.
   Solution:
   Let initial volume = V liters → Solvent = 0.4V
   After evaporation: (0.4V − 20)/(V − 20) = 0.25
   0.4V − 20 = 0.25V − 5 → 0.15V = 15 → V = 100 liters

4. Question: The ratio of compound interest to simple interest on a sum for 2 years at 8% p.a. is:
   Solution:
   SI = P × 8 × 2 /100 = 0.16P
   CI = P[(1.08)² − 1] = 0.1664P
   Ratio = 0.1664P / 0.16P = 1.04 or 26:25

5. Question: A cube of side 12 cm is melted and recast into 27 identical smaller cubes. Find the side of each small cube.
   Solution:
   Volume = 12³ = 1728 cm³
   Volume of each small cube = 1728/27 = 64 cm³
   Side = ∛64 = 4 cm

6. Question: An article is marked 25% above cost. After a 10% discount, the dealer makes a profit of ₹90. Find cost price.
   Solution:
   Let CP = ₹100x → MP = 125x → SP = 0.9 × 125x = 112.5x
   Profit = 12.5x = 90 → x = 7.2
   CP = 100 × 7.2 = ₹720

7. Question: If a² + b² + c² = ab + bc + ca, then find the value of (a³ + b³ + c³)/abc.
   Solution:
   Condition holds only if a = b = c (proves via ½[(a−b)²+(b−c)²+(c−a)²]=0)
   Substitute a=b=c: Numerator = 3a³, Denominator = a³ → 3

8. Question: A boat travels 30 km downstream in 3 hours and returns upstream in 5 hours. Find stream speed.
   Solution:
   Downstream speed = 10 km/h, Upstream = 6 km/h
   Boat speed = (10+6)/2 = 8, Stream = (10−6)/2 = 2 km/h
