I was interviewed in Jan 2025.
A control system is a system that manages, commands, directs, or regulates the behavior of other devices or systems.
Control systems are used to maintain desired outputs in various processes.
They can be implemented using hardware, software, or a combination of both.
Examples include thermostat control in HVAC systems, cruise control in vehicles, and automatic voltage regulators in power systems.
An Air Circuit Breaker (ACB) is a type of circuit breaker that operates by using air as the medium to extinguish the arc formed when the circuit is interrupted.
ACB is designed to protect electrical circuits from overloads and short circuits.
When a fault occurs, the ACB trips and interrupts the flow of current by separating the contacts.
The arc formed during interruption is extinguished by the blast of compressed air.
AC...
A relay is an electrically operated switch that controls a high-power circuit with a low-power signal.
Relays are used to control circuits by opening or closing contacts in response to a signal
They are commonly used in industrial applications to control motors, lights, heaters, and other high-power devices
Relays can be classified based on their operation, such as electromechanical relays, solid-state relays, and reed re
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease voltage levels in electrical circuits.
Types of transformers include step-up transformers, step-down transformers, isolation transformers, and autotransformers.
Step-up transformers increase voltage levels, while step-down transformers decrease...
CTs and PTs are devices used in electrical systems to measure current and voltage respectively.
Current Transformers (CTs) are used to measure current in electrical circuits by stepping down the current to a safe level for measurement.
Potential Transformers (PTs) are used to measure voltage in electrical circuits by stepping down the voltage to a safe level for measurement.
CTs and PTs are commonly used in power distribu...
HT voltage is higher than LT voltage. HT is used for long-distance transmission while LT is used for distribution within buildings.
HT voltage is typically above 1000V, while LT voltage is below 1000V.
HT voltage is used for long-distance transmission of electricity, such as from power plants to substations.
LT voltage is used for distribution within buildings or small areas, such as powering appliances and lighting.
HT li...
A megger is a portable instrument used to measure the insulation resistance of electrical equipment.
Megger is short for megohmmeter.
It is used to detect insulation faults in cables, wires, and electrical equipment.
The instrument applies a high voltage to the insulation and measures the resistance.
A megger typically has a hand-cranked generator to produce the high voltage.
Results are displayed in ohms or megohms.
VCBs use vacuum as the arc quenching medium while ACBs use air. VCBs are more reliable and require less maintenance.
VCBs use vacuum as the arc quenching medium, while ACBs use air
VCBs are more reliable and require less maintenance compared to ACBs
VCBs have higher breaking capacity than ACBs
VCBs are more suitable for medium voltage applications, while ACBs are commonly used in low voltage applications
Maintenance is the process of ensuring equipment and facilities are kept in good working condition. Types include preventive, predictive, corrective, and proactive maintenance.
Maintenance is the process of preserving the condition of equipment and facilities.
Preventive maintenance involves regular inspections and servicing to prevent breakdowns.
Predictive maintenance uses data and analytics to predict when maintenance ...

I applied via Naukri.com and was interviewed before May 2021. There was 1 interview round.
I applied via Walk-in and was interviewed before Apr 2020. There were 5 interview rounds.
I was interviewed before Sep 2020.
Round duration - 140 minutes
Round difficulty - Medium
Test timing was at 2:00 pm , it was conducted in a college and the environment was good for the test. Camera was a primary part of test, so no suspicious activity.

Given two numbers represented as arrays, calculate their sum and return the result as an array.
Iterate through the arrays from right to left, adding digits and carrying over if necessary
Handle cases where one array is longer than the other by considering the remaining digits
Ensure the final sum array does not have any leading zeros
Round duration - 20 minutes
Round difficulty - Easy
The round was conducted at around 12 p.m. I was called at the college location and then it was conducted. The interviewer was quite polite and frank.
Round duration - 8 minutes
Round difficulty - Easy
This round was conducted right after finishing and clearing the technical round at the same place and on the same day.
Tip 1 : Practice atleast 2-3 Coding problems daily so your logic building becomes stronger.
Tip 2 : Exercise problems based on OOPS concepts and others too.
Tip 3 : If you can have your own project built, then it's the major point and will act as a plus point.
Tip 1 : Your resume should be in standard form, short and simple will be more effective.
Tip 2 : Whatever you have learned, you need to mention it in your resume as that will be your primary source of selection and having project on your resume is important.
