I applied via Walk-in and was interviewed before Mar 2019. There were 3 interview rounds.
Laws governing energy and its transformations in physical systems.
First law: Energy cannot be created or destroyed, only transferred or converted.
Second law: Entropy of a closed system always increases over time.
Third law: Absolute zero cannot be reached.
Applications in engineering, physics, and chemistry.
Examples: heat engines, refrigeration, combustion, chemical reactions.
Steam ejectors are devices that use steam to create a vacuum by entraining and compressing gases or vapors.
Steam ejectors work by using a high-pressure steam jet to create a low-pressure zone, which draws in gases or vapors from the surrounding area.
The entrained gases or vapors are then compressed and discharged through a diffuser, which increases their velocity and reduces their pressure.
Steam ejectors are commonly u...
Heat pump is a device that transfers heat from a lower temperature to a higher temperature.
Heat pump works on the principle of refrigeration cycle.
It consists of four main components: evaporator, compressor, condenser, and expansion valve.
The refrigerant absorbs heat from the low-temperature source (air, water, or ground) in the evaporator and gets converted into a gas.
The compressor then compresses the gas, which incr...
Grinding is a process of removing material from a workpiece using an abrasive wheel or belt.
Grinding is used to achieve high dimensional accuracy and surface finish.
It is commonly used in manufacturing industries for finishing operations.
Different types of grinding machines are used for different applications such as cylindrical, surface, and centerless grinding.
Grinding can be done manually or with the help of compute...

ASME Section 8 Div 1 provides guidelines for the design of pressure vessels to ensure safety and reliability.
It covers requirements for materials, design, fabrication, inspection, testing, and certification of pressure vessels.
Pressure vessels designed according to ASME Section 8 Div 1 must meet specific crit...
Types of packing in distillation column include structured packing, random packing, and trays.
Structured packing provides high efficiency due to its specific design and surface area
Random packing consists of randomly placed materials like ceramic saddles or metal rings
Trays are horizontal plates with holes for vapor and liquid to interact, such as sieve trays or bubble cap trays

I applied via Approached by Company and was interviewed in Oct 2023. There were 2 interview rounds.
LOTO stands for Lockout/Tagout, a permit system used to control hazardous energy sources during maintenance or servicing of equipment.
LOTO involves locking out energy sources to prevent accidental startup of machinery.
Tagout involves placing a tag on the energy isolation device to indicate it should not be operated.
Permit system requires a written procedure and authorization before work can begin.
Examples of energy sou...
The utility lines provided in the reactor are pressurized.
Utility lines in the reactor are typically pressurized to ensure efficient flow of materials.
Pressure in the utility lines is controlled and monitored to maintain optimal operation.
Examples of utility lines in a reactor include steam lines, cooling water lines, and gas supply lines.
