Rewinding a 72 slot 50 hp motor involves disassembling the motor, removing the old windings, and replacing them with new windings.
Disassemble the motor carefully to access the windings
Remove the old windings without damaging the core
Calculate the number of turns and wire gauge needed for the new windings
Wind the new coils carefully and evenly in the slots
Connect the windings properly and test the motor for functionalit
NO NC stands for Normally Open and Normally Closed. They refer to the state of a switch or relay when it is not activated.
NO (Normally Open) - the switch is open (off) when not activated
NC (Normally Closed) - the switch is closed (on) when not activated
Used in electrical circuits to control the flow of current
Commonly used in control panels, automation systems, and safety circuits
Earthing points are checked by using a multimeter to measure the resistance between the earthing point and the earth electrode.
Use a multimeter set to the resistance mode
Connect one probe to the earthing point and the other probe to the earth electrode
Check the resistance reading on the multimeter
A low resistance reading indicates a good earthing connection
Repeat the process for all earthing points in the system
Fan rewinding is the process of replacing the copper wire coils in the stator of a fan motor to restore its functionality.
Disconnect the fan from the power source before starting the rewinding process.
Remove the fan blades and outer casing to access the stator.
Carefully unwind the old copper wire coils from the stator and measure their length and gauge.
Select the appropriate gauge and length of copper wire for rewindin...
A contactor relay is an electrical device used to control a high-power circuit with a low-power signal.
Contactor relay consists of a coil, contacts, and an enclosure.
When the coil is energized, it creates a magnetic field that pulls the contacts together to close the circuit.
Contactor relays are commonly used in motor control circuits to start and stop motors.
They can also be used in lighting control, heating systems,

I appeared for an interview before Mar 2024.
The aptitude test is beneficial and somewhat easy.
The coding test was both successful and somewhat challenging.
Group discussions are highly beneficial.
Object-Oriented Programming (OOP) in Python is a programming paradigm based on objects and classes to structure code effectively.
Encapsulation: Bundling data and methods that operate on the data within one unit (class). Example: class Dog with attributes and methods.
Inheritance: Mechanism to create a new class using properties of an existing class. Example: class Bulldog inherits from class Dog.
Polymorphism: Ability to...
Machine learning algorithms enable computers to learn from data and make predictions or decisions without explicit programming.
Supervised Learning: Algorithms learn from labeled data. Example: Linear Regression for predicting house prices.
Unsupervised Learning: Algorithms identify patterns in unlabeled data. Example: K-Means Clustering for customer segmentation.
Reinforcement Learning: Algorithms learn by interacting wi...
I possess a blend of relevant skills, experience, and a strong commitment to contributing positively to your team.
Strong analytical skills: In my previous role, I successfully analyzed market trends to improve product positioning.
Team collaboration: I led a project team that increased efficiency by 20% through effective communication and delegation.
Adaptability: I quickly learned new software tools that enhanced our wo...
I appeared for an interview in Sep 2017.
A sorting algorithm is a method of arranging elements in a specific order.
Sorting algorithms can be categorized as comparison-based or non-comparison-based.
Common sorting algorithms include bubble sort, insertion sort, selection sort, merge sort, quicksort, and heapsort.
Efficiency of sorting algorithms is measured by their time complexity, space complexity, and stability.
Example: Sorting an array of strings in alphabet
I applied via Walk-in and was interviewed before Apr 2021. There were 2 interview rounds.

O(n) refers to linear time and space complexity.
O(n) means that the time or space required by an algorithm grows linearly with the size of the input.
It implies that the algorithm's performance is directly proportional to the input size.
For example, if an algorithm takes 10 seconds to process 100 elements, it would take 20 seconds to process 200 elements.
O(n) complexity is considered efficient and desirable in most case

Virtual inheritance allows a derived class to inherit from a base class without creating duplicate base class subobjects.
Virtual inheritance is used to resolve the Diamond Problem in C++ where a class inherits from two classes that have a common base class.
It ensures that only one copy of the base class is inherited by the derived class.
Virtual inheritance introduces a virtual base class subobject to the derived class,...
A class for string operations can include methods for concatenation, substring extraction, length calculation, etc.
Create a class with methods like concatenateStrings, extractSubstring, calculateLength, etc.
Use string manipulation functions like substring, concat, length, etc. within the class methods.
Ensure error handling for edge cases like empty strings or out-of-bounds indices.
Example: class StringOperations { conc...

Copy constructor is a special type of constructor which creates a new object as a copy of an existing object.
Copy constructor is used to initialize a new object as a copy of an existing object.
It takes an object of the same class as a parameter.
It is called automatically when a new object is created from an existing object.
Example: class MyClass { public: MyClass(const MyClass& obj) { // copy constructor logic } };
Copy constructor is used to create a new object as a copy of an existing object, while assignment operator is used to assign values from one object to another.
Copy constructor is called when a new object is created from an existing object, while assignment operator is called when an existing object is assigned values from another object.
Copy constructor creates a new object with its own memory space, while assignment o...
A static function is a function that is associated with a class rather than an instance of the class.
Static functions can be called without creating an instance of the class.
Static functions are commonly used for utility functions that do not require access to instance-specific data.
Static functions are declared using the 'static' keyword in many programming languages.
Example: 'Math.max()' in JavaScript is a static fun
Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.
Start with 0 and 1 as the first two numbers in the series
Add the previous two numbers to get the next number in the series
Repeat this process to generate the Fibonacci series
Singleton design pattern ensures a class has only one instance and provides a global point of access to it.
Ensures a class has only one instance
Provides a global point of access to that instance
Commonly used in scenarios where only one instance of a class is needed, such as database connections or logging
