Core Engineering Subjects
Branch-wise placement revision for ECE, EEE, Mechanical, Civil and Chemical students — cheat sheets, formulas, company interview questions and quick quizzes. CSE/IT students: head to Core CS.
Digital Electronics & VLSI
The most-asked ECE core in semiconductor and product company drives: Boolean logic, sequential design, FSMs and timing closure.
Microprocessors & Embedded
8051/ARM architecture, interrupts, timers and the communication buses every embedded interview opens with.
Analog Electronics
Op-amps, feedback amplifiers, small-signal models, active filters and oscillators — the analog half of Qualcomm, TI and Bosch technical rounds.
Electrical Machines & Drives
Transformers, DC machines and induction motors — torque-speed behaviour, testing and starters asked in every core electrical drive.
Power Systems & Control
Transmission lines, fault analysis, protection relays and control systems — stability, Bode/Nyquist and PID tuning asked at Tata Power and core PSUs.
Power Electronics & Drives
Thyristors and converters, choppers, inverters, PWM techniques and induction motor speed control — the core EEE subject for ABB, Siemens, Tata Motors and PSU interviews.
Strength of Materials & Machine Design
SFD/BMD, Mohr's circle, theories of failure and fatigue — the drawing-board questions Tata Motors and L&T Heavy open with.
Thermal Engineering & Fluid Mechanics
Cycles (Otto, Diesel, Rankine), Bernoulli, boundary layers and pipe losses — the applied-thermodynamics round at Thermax, Maruti and ISRO.
Manufacturing & Industrial Engineering
Casting and welding defects, machining kinematics, CNC G-codes and inventory models (EOQ/JIT) — the manufacturing round of Tata Motors, L&T, Bosch and Ashok Leyland.
Structural Engineering & RCC
Limit state design to IS 456, prestressed concrete and indeterminate structures — the L&T Construction and DMRC technical round.
Geotechnical & Transportation Engineering
Terzaghi bearing capacity, compaction vs consolidation, sight distances and pavement design — the site-and-soil half of civil interviews.
Fluid Mechanics & Hydraulic Structures
Bernoulli's theorem, pipe friction, open-channel flow, pumps and turbines, and dam spillway hydraulics — core Civil rounds at L&T, PWD, irrigation boards and NTPC.
Transport Phenomena & Reaction Engineering
Mass transfer & distillation, ideal reactors and RTD — the Reliance, IOCL and ONGC process-interview core.
Mass Transfer & Reaction Engineering
Distillation and McCabe-Thiele, absorption, Arrhenius kinetics and batch/PFR/CSTR reactor design — the separation and kinetics rounds at Reliance, IOCL, and pharma companies.
Engineering Mathematics for Placements & GATE
Linear algebra, calculus and probability — the common paper of every branch's aptitude-technical round and the GATE engineering-maths section.
