- Q1. What is filter in dot net core
- Ans.
Filters in .NET Core are used to intercept HTTP requests and responses.
Filters are used to add cross-cutting concerns to MVC applications.
They can be used for authentication, authorization, logging, exception handling, etc.
Filters can be applied globally, at the controller level, or at the action level.
Examples of filters include AuthorizeFilter, ExceptionFilter, and ActionFilter.
- Q2. What is dependency injection
- Ans.
Dependency injection is a design pattern that allows objects to be loosely coupled and dependencies to be injected at runtime.
Dependency injection is a way to achieve inversion of control.
It helps in creating modular and testable code.
Dependencies are provided to a class through constructor injection, property injection, or method injection.
It promotes code reusability and maintainability.
Example: In a .NET Core applic...
- Q3. Different between Transient,Add Scope and AddSingleton
- Ans.
Transient creates a new instance every time it is requested, Scoped creates a new instance per scope, Singleton creates a single instance for the entire application.
Transient: Creates a new instance every time it is requested.
AddScoped: Creates a new instance per scope, such as per HTTP request.
AddSingleton: Creates a single instance for the entire application.
Example: Transient can be used for lightweight services tha...
- Q4. Difference between dataset and datareader
- Ans.
Dataset is an in-memory representation of a relational database, while DataReader is a forward-only, read-only stream of data.
Dataset is a disconnected architecture, while DataReader is a connected architecture.
Dataset can hold multiple tables and relationships, while DataReader can only hold a single table.
Dataset can be used for data manipulation and updates, while DataReader is read-only.
Dataset requires more memory...
- Q5. Whai is Sql Join and why do we need it
- Ans.
SQL 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 in a single query.
It helps in avoiding data redundancy and improving query performance.
Different types of joins include inner join, left join, right join, and full outer join.
Join conditions are specified using the ON keyword.
Example: SELECT * FROM table1 JOIN table2 ON tabl
- Q6. How to create a table using MYSQL
- Ans.
To create a table using MYSQL, use the CREATE TABLE statement followed by the table name and column definitions.
Use the CREATE TABLE statement to create a new table
Specify the table name after the CREATE TABLE statement
Define the columns and their data types within parentheses
Add any additional constraints or attributes to the columns
Example: CREATE TABLE employees (id INT, name VARCHAR(50), age INT)

Examples: Creating an index on a column in a table to speed up search queries
Interview Preparation Tips
Tip 1 : Strengthen your coding, algorithms. This is one most important thing for OYO. Practice Graph, tree, DP, greedy, recursion, data structures questions.
Tip 2 : OS, DBMS concepts will give you an edge over others. Like serialisation, index, deadlock, semaphore
Tip 3 : Only mention those projects in your resume which you are very clear about. They don't ask for detailed explanation, just an overall idea about your projects will increase your chances
Tip 1 : Mention college projects wisely. No need to mention fancy projects. Any project that you can describe to the interviewer will be a best solution
Tip 2 : Neat & clean resume with your skills, technical stacks that you mastered. That's all. They don't require you to be very active in extra-curricular activities, and these things will not give you any advantage.
Tip 3 : Keep it of single page
