I applied via Walk-in and was interviewed in Dec 2022. There were 3 interview rounds.
Line balancing is the process of evenly distributing workload among workstations in a production line to optimize efficiency.
Line balancing aims to minimize idle time and maximize productivity
It involves assigning tasks to workstations based on their processing times
Example: In a manufacturing plant, line balancing ensures each workstation has a similar amount of work to do
Assembly balancing is the process of optimizing the work distribution among different workstations to improve efficiency and productivity.
Assembly balancing involves assigning tasks to different workstations in a way that minimizes idle time and maximizes throughput.
It helps in achieving a smooth flow of work and prevents bottlenecks in the production process.
Factors considered in assembly balancing include task time, ...
Cycle time is the total time it takes to complete a process, while tact time is the time it takes to produce one unit.
Cycle time includes all the time spent on a process, including wait time and processing time.
Tact time is the rate at which a product must be produced to meet customer demand.
For example, if a process takes 10 minutes to complete and the customer demand is 100 units per hour, the tact time would be 0.6 ...
Production is the process of creating goods or services, while quality refers to the standard of those goods or services.
Production involves the manufacturing or creation of goods or services.
Quality refers to the standard or level of excellence of those goods or services.
Production and quality are closely linked as the goal is to produce high-quality products efficiently.
Examples: In a manufacturing plant, production ...
OLE stands for Overall Equipment Effectiveness and OEE stands for Overall Labor Effectiveness.
OLE measures the overall performance of equipment in a manufacturing plant.
OEE measures the overall performance of labor in a manufacturing plant.
Both metrics are used to identify areas for improvement and optimize efficiency.
Example: OLE can help identify equipment downtime and OEE can help identify labor productivity issues.
7QC tools are a set of quality control tools used to identify and solve quality problems in manufacturing processes.
7QC tools include Pareto chart, cause-and-effect diagram, control chart, histogram, scatter diagram, flowchart, and check sheet.
They help in identifying and analyzing quality problems, determining root causes, and implementing corrective actions.
They are used to improve product quality, reduce defects, an...
PPAP and APQP are quality management systems used in manufacturing.
PPAP stands for Production Part Approval Process and is used to ensure that manufactured parts meet customer requirements.
APQP stands for Advanced Product Quality Planning and is used to plan and manage the design and development of new products.
Both systems are commonly used in the automotive industry but can be applied to other manufacturing industrie...
Pareto is a principle that states 80% of effects come from 20% of causes.
Also known as the 80/20 rule
Used in business to identify the most important factors
Can be applied to various fields such as economics, engineering, and social sciences
Example: 80% of a company's profits come from 20% of its customers
OEE can be calculated by multiplying Availability, Performance, and Quality percentages.
Calculate Availability by dividing Operating Time by Planned Production Time.
Calculate Performance by dividing Actual Production by Maximum Production.
Calculate Quality by dividing Good Units by Total Units Produced.
Multiply Availability, Performance, and Quality percentages to get OEE.

Initial setting time of cement is the time taken by cement to harden and resist penetration by a standard needle.
Initial setting time is affected by factors like temperature, water-cement ratio, and type of cement.
The standard needle used for testing has a diameter of 1.13 mm and a length of 50 mm.
The initial setting time of ordinary Portland cement is around 30 minutes.
The initial setting time of rapid hardening cemen

Questions related to electrical engineering concepts such as transformers, AC and DC, motor, electromagnetic induction law, and Ohm's law.
Transformers are devices that transfer electrical energy from one circuit to another through electromagnetic induction.
AC (alternating current) changes direction periodically while DC (direct current) flows in one direction only.
A motor is a device that converts electrical energy int...
Questions related to generators, power transmission, and thermocouples.
Types of generators include diesel, gas, wind, and hydroelectric.
India's generation capacity is around 370 GW.
Maximum power transmission in India is around 1,050 GW.
Transmission of maximum power is important to ensure efficient and reliable power supply.
A thermocouple is a device used to measure temperature and is commonly used in industrial applica
Basic Study
I applied via Company Website and was interviewed in Apr 2021. There was 1 interview round.
I have 2 years of experience in the wind field.
I have worked on wind turbine design and optimization projects.
I have conducted wind resource assessments for potential wind farm sites.
I have experience in analyzing wind data and performing wind flow modeling.
I have knowledge of wind energy conversion systems and their components.
I have worked with software tools like WindPRO and WAsP for wind energy analysis.
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, called the primary and secondary coils, wrapped around a magnetic core.
When an AC current flows through the primary coil, it creates a magnetic field th...
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.
Ohm's law is represented by the equation V = IR, where V is voltage, I is current, and R is resistance.
The power formula is P = VI, where P is power, V is voltage, and I is current.
Ohm's law is used to calculate the resistance of a circuit and to determine the amount of current flowing ...
Questions related to torque, gearbox, torque limiter and coupling failure, yawing system bearing, and accumulator.
Torque is a measure of rotational force.
Gearbox works by transmitting power from the engine to the wheels.
Torque limiter failure can be caused by overloading or overheating.
Coupling failure can be caused by misalignment or excessive torque.
Yawing system bearing is a type of roller bearing used to support th...
