I applied via LinkedIn and was interviewed before Nov 2023. There was 1 interview round.
Generics in programming allow for the creation of classes, interfaces, and methods that operate on data types without specifying the actual type at compile time.
Generics provide type safety by allowing the use of parameterized types.
They enable code reusability by writing generic algorithms that work with different data types.
Example: List
Conflict arises and implementing class must explicitly implement the method from both interfaces.
Conflict arises when implementing class implements both interfaces
Implementing class must explicitly implement the method from both interfaces
Example: Interface A and Interface B both have a method named 'foo', implementing class must provide implementation for 'foo' from both interfaces
Enums are a set of named constants representing a group of related values.
Enums in C# are value types that allow you to define a set of named constants.
Enums can be used to improve code readability and maintainability by giving meaningful names to integral values.
Example: enum Days { Monday, Tuesday, Wednesday, Thursday, Friday }
const and Readonly are used in C# to declare constant values, but Readonly can be assigned a value at runtime.
const keyword is used to declare constants at compile time
const values cannot be changed once assigned
Readonly keyword is used to declare constants whose value can be assigned at runtime
Readonly values can only be assigned in the constructor or at the time of declaration
The 'out' keyword is used in C# to pass arguments by reference, allowing the method to modify the value of the argument.
Used to pass arguments by reference in C#
Allows the method to modify the value of the argument
Must be assigned a value inside the method before returning
Indexers in C# allow objects to be indexed like arrays, enabling objects to be accessed using square brackets.
Indexers are special type of properties in C# that allow objects to be indexed like arrays.
They are defined using 'this' keyword followed by square brackets and the index parameters.
Indexers can be used to access elements of a collection or class using square brackets.
Example: public string this[int index] { ge...
Sealed class is a class that cannot be inherited. It is used to prevent derivation of a class.
Sealed classes are declared using the 'sealed' keyword.
They are often used when a class is not intended to be inherited or overridden.
Sealed classes can have private constructors to prevent instantiation.
Example: 'sealed class MyClass {}'
Managed code is code that is executed by the Common Language Runtime (CLR) in .NET framework.
Managed code is written in high-level languages like C#, VB.NET, etc.
It is compiled into Intermediate Language (IL) which is then executed by the CLR.
CLR provides services like memory management, security, exception handling, etc. for managed code.
Managed code runs in a managed environment where the runtime takes care of variou
Constructor chaining is the process of calling one constructor from another constructor within the same class.
Allows for reusing code and avoiding duplication
Can be achieved using 'this()' keyword in C#
Example: public MyClass() : this(0) { }
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
Start_up class is a class in .NET framework used to configure services and middleware for an application.
Start_up class is used to configure services like dependency injection, middleware, and routing in an ASP.NET Core application.
It contains methods like ConfigureServices() to add services to the dependency injection container and Configure() to set up middleware pipeline.
Start_up class is typically found in the root...

const is compile-time constant, while readonly is runtime constant.
const values are determined at compile time and cannot be changed during runtime
readonly values can be assigned a value either at the declaration or in the constructor and can be changed at runtime
const is used for values that are known at compile time, like mathematical constants
readonly is used when the value needs to be initialized at runtime, like d
I applied via LinkedIn and was interviewed in Nov 2024. There was 1 interview round.
Program to calculate factorial of a number using for loop
Initialize a variable to store the factorial result
Use a for loop to iterate from 1 to the given number
Multiply the current value with the factorial result in each iteration
Return the factorial result

I applied via Campus Placement and was interviewed in Oct 2024. There were 2 interview rounds.
Number series in aptitude involves identifying the pattern in a sequence of numbers and predicting the next number.
Look for patterns such as arithmetic progression, geometric progression, or a combination of both.
Check for alternate numbers, differences between consecutive numbers, or multiplication factors.
Consider prime numbers, squares, cubes, or other mathematical operations applied to the series.
Example: 2, 4, 6, ...
Relationships in verbal communication are crucial for effective collaboration and understanding.
Verbal communication involves both verbal and non-verbal cues
Active listening is key to building strong relationships in verbal communication
Clarity and conciseness in speech can enhance relationships
Empathy and understanding of others' perspectives are important in verbal relationships
The four branches of OOP are encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit.
Inheritance: Allowing a class to inherit properties and behavior from another class.
Polymorphism: The ability for objects of different classes to respond to the same method call.
Abstraction: Hiding the complex implementation details and showing only
Structures in C are user-defined data types that allow grouping of variables of different data types under a single name.
Structures are used to represent a record which consists of different data types.
They are defined using the 'struct' keyword.
Each variable in a structure is called a member.
Structures can be nested within other structures.
Example: struct employee { int emp_id; char emp_name[50]; float emp_salary; };

I was interviewed in Nov 2024.
The aptitude test evaluates problem-solving, coding skills, and logical reasoning, offering a fair challenge to showcase technical expertise.
I address conflicts in team projects by promoting open communication, active listening, and seeking compromise.
Encourage open communication among team members to address conflicts early on
Practice active listening to understand all perspectives and concerns
Seek compromise and find common ground to resolve conflicts effectively
Interface is a contract that defines the methods a class must implement, while an abstract class can have both implemented and abstract methods.
Interface can only have abstract methods and cannot have any implementation, while abstract class can have both abstract and implemented methods.
A class can implement multiple interfaces but can only inherit from one abstract class.
Interfaces are used to achieve multiple inheri...

Collections are data structures that store and organize multiple elements in a single unit.
Collections provide methods to add, remove, and manipulate elements.
Examples of collections include arrays, lists, sets, and maps.
Collections can be used to efficiently manage and access large amounts of data.
A constructor is a special method in a class that is automatically called when an object of that class is created.
Constructors have the same name as the class they belong to
They are used to initialize the object's state
Constructors can have parameters to customize the initialization process
Data science is a field that uses scientific methods, algorithms, and systems to extract knowledge and insights from structured and unstructured data.
Data science involves collecting, analyzing, and interpreting large amounts of data to make informed decisions.
It combines statistics, machine learning, and domain knowledge to uncover patterns and trends in data.
Data scientists use programming languages like Python and R...
