10+ Stride Ventures Interview Questions and Answers

The number of sessions in an application is not fixed and can vary based on the application's design and requirements.

• The number of sessions in an application can depend on factors such as user activity, server capacity, and session management techniques.

• For example, a simple web application may have a limited number of sessions based on the server's capacity, while a complex enterprise application may have a larger number of sessions to handle multiple users and tasks.

• Sessio...read more

IEnumerable is used for in-memory collection operations, while IQueryable is used for database query operations.

• IEnumerable is used for querying data from in-memory collections like arrays, lists, etc.

• IQueryable is used for querying data from a database using LINQ to SQL or Entity Framework.

• IEnumerable executes the query in-memory, while IQueryable executes the query on the database server.

• IEnumerable is suitable for LINQ to Objects, while IQueryable is suitable for LINQ to E...read more

Temp table is a temporary table that is created in the memory or on the disk and is used to store data temporarily.

• Temp table is created using the CREATE TABLE statement with the # symbol before the table name.

• It is used to store intermediate results during complex queries or stored procedures.

• Temp tables are automatically dropped when the session that created them ends or when the connection is closed.

• Example: CREATE TABLE #tempTable (id INT, name VARCHAR(50))

• Example: INSERT...read more

Repository design pattern is a design pattern that separates the data access logic from the business logic in an application.

• It helps in achieving separation of concerns by isolating the data access code in a separate layer.

• It provides a centralized way to access data from various sources such as databases, web services, etc.

• It makes the codebase more maintainable and testable by abstracting the data access logic.

• Example: Using a repository pattern to handle database operatio...read more

Pillars of OOP are Abstraction, Encapsulation, Inheritance, and Polymorphism. SOLID principles are Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion.

• Pillars of OOP: Abstraction - hiding complex implementation details, Encapsulation - bundling data and methods together, Inheritance - creating new classes from existing ones, Polymorphism - ability to use objects of different classes interchangeably

• SOLID principles: Single R...read more

Authentication in Web API involves verifying the identity of a user or system before granting access to resources.

• Authentication headers like Authorization header are used to send credentials

• Web API can use various authentication methods like JWT, OAuth, Basic Authentication

• Authentication middleware is used to validate credentials and generate tokens

• Access control lists (ACLs) can be used to define permissions for different users

SQL procedure is used to perform an action, while function returns a value.

• Procedures can modify data, while functions cannot.

• Functions can be used in SQL statements, while procedures cannot.

• Functions must return a value, while procedures do not have to.

• Example of a procedure: CREATE PROCEDURE myProcedure AS SELECT * FROM myTable;

• Example of a function: CREATE FUNCTION myFunction() RETURNS INT AS BEGIN RETURN 5; END;

Dependency injection is a design pattern where components are given their dependencies rather than creating them internally.

• Dependency injection helps in achieving loose coupling between classes.

• It allows for easier testing by providing a way to mock dependencies.

• There are three types of dependency injection - constructor injection, setter injection, and interface injection.

Join is used to combine rows from two or more tables based on a related column between them.

• Join is used to retrieve data from multiple tables based on a related column.

• Self join is when a table is joined with itself.

• Example: SELECT e1.name, e2.name FROM employees e1, employees e2 WHERE e1.manager_id = e2.employee_id;

MVC stands for Model-View-Controller, a software design pattern for organizing code in a web application.

• MVC separates the application into three main components: Model (data), View (UI), and Controller (logic).

• Model represents the data and business logic of the application.

• View is responsible for displaying the data to the user.

• Controller handles user input, updates the model, and selects the view to display.

• MVC promotes code reusability, modularity, and separation of concer...read more

Async-await is a feature in C# that allows asynchronous programming for better performance and responsiveness.

• Async-await allows methods to run asynchronously, improving performance by not blocking the main thread.

• It simplifies asynchronous programming by using keywords 'async' and 'await'.

• Example: async Task GetDataAsync() { await Task.Delay(1000); return 1; }

DI concept in .NET Core allows for loosely coupled components by injecting dependencies at runtime.

• DI stands for Dependency Injection

• It helps in achieving Inversion of Control (IoC)

• Reduces tight coupling between components

• Improves testability and maintainability of code

• Example: Services are injected into controllers in ASP.NET Core
