Sets, dictionaries and entities are data structures in Python with different properties and use cases.
Sets are unordered collections of unique elements, useful for operations like union and intersection.
Dictionaries are key-value pairs, allowing for efficient lookup and modification of values.
Entities can refer to any object or data type in Python, including variables, functions, and classes.
Sets and dictionaries can b...
For loop in Python is used to iterate over a sequence of elements.
Syntax: for variable in sequence:
Example: for i in range(5): print(i)
Can be used with lists, tuples, strings, dictionaries, etc.
Can use break and continue statements to control loop flow
Performance of databases is crucial for efficient production engineering.
Optimizing queries and indexing can improve database performance.
Using caching mechanisms can reduce database load and improve response time.
Regular maintenance and updates can prevent performance degradation over time.
Choosing the right database technology for the specific use case can also impact performance.
Monitoring and analyzing database per...
Top command displays real-time information about running processes in Unix.
Displays system summary information as well as a list of processes.
Provides information about CPU usage, memory usage, and process details.
Can be used to sort processes by various criteria such as CPU usage or memory usage.
Can be used to send signals to processes, such as killing a process.
Example: 'top -o cpu' sorts processes by CPU usage.
I was interviewed in Jun 2017.

Condensers are devices used to condense a substance from its gaseous to its liquid state.
There are two main types of condensers: air-cooled and water-cooled.
Air-cooled condensers use air as the cooling medium, while water-cooled condensers use water.
Examples of air-cooled condensers include car radiators and air conditioning units.
Examples of water-cooled condensers include cooling towers and refrigeration systems.
Othe...

Azeotropic distillation is a process used to separate azeotropes, which are mixtures of liquids that boil at a constant temperature.
Azeotropic distillation involves adding a third component to the mixture to break the azeotrope.
The third component forms a new azeotrope with one of the original components, which can then be separated from the other component.
This process is commonly used in the production of ethanol, wh...
Reynolds number is a dimensionless quantity used to predict fluid flow patterns and turbulence.
Reynolds number is calculated as the ratio of inertial forces to viscous forces in a fluid.
It is used to determine whether a fluid flow is laminar or turbulent.
The range of Reynolds number for laminar flow is less than 2300, while for turbulent flow it is greater than 4000.
In between these values, the flow may be transitional...

I applied via Company Website and was interviewed in Dec 2021. There was 1 interview round.
Distillation is a process of separating components of a liquid mixture based on their different boiling points.
Distillation involves heating a liquid mixture to vaporize the more volatile components.
The vapor is then cooled and condensed back into a liquid, separating it from the less volatile components.
The separated components can have different boiling points, allowing for purification or concentration of specific s...
Heat transfer is the process of energy transfer between objects or substances due to temperature differences.
Heat transfer can occur through conduction, convection, and radiation.
Conduction is the transfer of heat through direct contact between objects or substances.
Convection is the transfer of heat through the movement of fluids or gases.
Radiation is the transfer of heat through electromagnetic waves.
Examples of heat...

I applied via Naukri.com and was interviewed before Apr 2023. There was 1 interview round.
Various solvents are used in production engineering depending on the specific application, such as water, alcohols, hydrocarbons, and acids.
Water is commonly used as a solvent for cleaning and rinsing processes.
Alcohols like ethanol are used for dissolving oils, resins, and waxes.
Hydrocarbons such as hexane are used for extracting oils and fats.
Acids like sulfuric acid are used for pickling and cleaning metal surfaces.
I applied via Walk-in and was interviewed in Sep 2021. There were 2 interview rounds.

OOPs concepts revolve around classes, objects, inheritance, polymorphism, and encapsulation.
Classes are blueprints for objects, defining their properties and behaviors.
Objects are instances of classes, representing real-world entities.
Inheritance allows a class to inherit properties and methods from another class.
Polymorphism enables objects to be treated as instances of their parent class.
Encapsulation restricts acces...
