I applied via Campus Placement and was interviewed in Jul 2021. There were 3 interview rounds.
A CNC machine is a computer-controlled machine tool used for precision machining of various materials.
CNC stands for Computer Numerical Control.
It uses pre-programmed instructions to control the movement of the machine.
CNC machines can perform a wide range of operations such as cutting, drilling, milling, and turning.
They are commonly used in manufacturing industries for mass production of parts.
CNC machines offer high...

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
Stress is the external force acting on an object, measured in units like Newtons per square meter (N/m^2) or Pascals (Pa).
Strain is the measure of deformation or change in shape of a material due to stress, expressed as a ratio or percentage.
Example: When you stretch a rubber band (apply stress), it elongates (strain

I applied via Referral and was interviewed in Jul 2023. There were 3 interview rounds.
1st angle and 3rd angle projection differ in the placement of the object and the observer in relation to the projection plane.
1st angle projection places the object in front of the projection plane, while 3rd angle projection places the object behind the projection plane.
In 1st angle projection, the observer views the object from the opposite side of the projection plane, while in 3rd angle projection, the observer vie...

This round was conducted on online and it consists of Aptitude and core questions
Theories of failure are mathematical models used to predict the failure of materials under different loading conditions.
Theories of failure help engineers design structures that can withstand different types of loads.
Some common theories of failure include maximum shear stress theory, maximum normal stress theory, and maximum strain energy theory.
These theories are based on different assumptions about the behavior of m...
Diesel cycle is a thermodynamic cycle used in diesel engines to convert heat into work.
Air is compressed in the cylinder, causing its temperature to rise.
Fuel is injected into the cylinder, igniting due to the high temperature.
The expanding gases push the piston, converting heat into mechanical energy.
Exhaust gases are expelled from the cylinder.
Diesel cycle is more efficient than Otto cycle used in gasoline engines.

I applied via LinkedIn and was interviewed in Oct 2022. There were 2 interview rounds.
Young's modulus is a measure of stiffness of a material while ultimate tensile strength is the maximum stress a material can withstand.
Young's modulus is the ratio of stress to strain in a material under tension or compression.
Ultimate tensile strength is the maximum stress a material can withstand before breaking.
Young's modulus is measured in pascals (Pa) while ultimate tensile strength is measured in newtons per squ

Enthalpy is the sum of internal energy and the product of pressure and volume.
Enthalpy is a thermodynamic property of a system.
It is represented by the symbol 'H'.
It is defined as the sum of internal energy and the product of pressure and volume.
Enthalpy change is the difference between the enthalpies of the products and reactants in a chemical reaction.
Enthalpy is used in various fields including chemistry, physics, a
