I appeared for an interview in Jan 2017.
Various forging defects include cracks, laps, folds, and inclusions.
Cracks: occur due to improper cooling or excessive stress during forging.
Laps: happen when a portion of the metal folds over itself during forging.
Folds: occur when the metal is not properly shaped or aligned during forging.
Inclusions: foreign materials like oxides or impurities get trapped in the metal during forging.

I applied via Campus Placement and was interviewed before Mar 2020. There were 4 interview rounds.
I applied via Campus Placement
Practice all aptitude questions and also gain few core engineering knowledge for core section.
I applied via Campus Placement and was interviewed in Jul 2023. There were 3 interview rounds.
Each question carry different marks some carry 1 mark few 2 mark and few 5 marks we need to answer accordingly
20 question 60 minutes each question carry 5 marks
Entropy is a measure of disorder or randomness in a system.
Entropy is a concept in thermodynamics that quantifies the degree of randomness or disorder in a system.
It is a measure of the number of possible arrangements or states that a system can have.
Entropy increases with the increase in randomness or disorder.
For example, a deck of cards in perfect order has low entropy, but shuffling the deck increases the entropy.

The basic laws of thermodynamics govern the behavior of energy in various systems.
The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transferred or transformed.
The second law of thermodynamics states that the entropy of an isolated system always increases over time.
The third law of thermodynamics states that as the temperature approache...
Thermodynamic equilibrium is a state where there is no net change in the macroscopic properties of a system over time.
Thermodynamic equilibrium is a stable state where all forces and processes within a system are balanced.
In thermodynamic equilibrium, the system is at a uniform temperature and pressure throughout.
There is no transfer of heat or work between the system and its surroundings in thermodynamic equilibrium.

I applied via Campus Placement and was interviewed in Feb 2024. There were 2 interview rounds.
Aptitude test was held by an online platform.
The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.
Entropy in a closed system tends to increase over time
Heat energy naturally flows from hot to cold objects
Efficiency of energy conversion processes is limited by the second law of thermodynamics
Creep is the slow, time-dependent deformation of a material under constant load, while fatigue is the weakening of a material due to repeated loading and unloading.
Creep is a time-dependent phenomenon, while fatigue is a cyclic phenomenon.
Creep occurs at high temperatures and constant stress, while fatigue occurs at lower temperatures and varying stress levels.
Creep leads to permanent deformation, while fatigue can lea...
A thermocouple is a temperature sensor that consists of two different metals joined together at one end, which produces a voltage proportional to the temperature difference between the junction and the other end.
Consists of two different metals joined together at one end
Produces a voltage proportional to the temperature difference
Commonly used in industrial applications for temperature measurement
T-t-t diagram is a time-temperature-transformation diagram used in materials science to understand the transformation of phases in a material.
T-t-t diagram shows the relationship between time, temperature, and the transformation of phases in a material.
It helps in predicting the microstructure of a material based on the cooling rate and temperature.
T-t-t diagrams are commonly used in metallurgy to understand the phase
Annealing is a heat treatment process used to soften metals and increase their ductility.
Annealing involves heating a metal to a specific temperature and then slowly cooling it to room temperature.
This process helps to relieve internal stresses, improve machinability, and enhance electrical conductivity.
Examples of metals that are commonly annealed include steel, copper, and aluminum.
The critical temperature of steel is the temperature at which it loses its magnetic properties.
The critical temperature of steel is around 770°C (1420°F).
Above this temperature, steel becomes non-magnetic and undergoes a phase change.
The critical temperature varies depending on the type of steel and its composition.
Types of steel include carbon steel, alloy steel, stainless steel, and tool steel. They can be differentiated based on their composition, properties, and applications.
Carbon steel contains primarily carbon and iron, with low amounts of other elements. It is commonly used in construction and manufacturing.
Alloy steel contains additional elements such as manganese, silicon, and copper to enhance its properties. It is use...
