Globant DOT NET Developer Interview Questions, Process, and Tips

A constructor is a special method in a class that is automatically called when an instance of the class is created.

• Constructors have the same name as the class they belong to.

• They can be used to initialize the object's state or perform any necessary setup.

• Constructors do not have a return type.

• Example: public class Person { public Person() { // constructor code here } }

MVC is a design pattern used in .NET development, while .NET lifecycle refers to the stages of a .NET application's execution.

• MVC is a design pattern that separates an application into three main components: Model, View, and Controller.

• .NET lifecycle refers to the stages of a .NET application's execution, including initialization, execution, and termination.

• MVC helps in achieving separation of concerns and making the c...read more

Dispose is used to release unmanaged resources immediately, while Finalize is used for cleanup operations before an object is destroyed by the garbage collector.

• Dispose is called explicitly by the developer, while Finalize is called by the garbage collector.

• Dispose should be implemented in classes that directly interact with unmanaged resources.

• Finalize should be implemented in classes that need to release resources be...read more

DOM sanitizer in Angular is used to sanitize untrusted HTML to prevent XSS attacks.

• DOM sanitizer is used to sanitize HTML content before rendering it in Angular templates.

• It helps prevent Cross-Site Scripting (XSS) attacks by removing potentially harmful content.

• Angular provides a built-in DomSanitizer service for sanitizing HTML content.

• Example: Using DomSanitizer in Angular template to sanitize a URL before rendering

I use Ngrx for state management in my current project by defining actions, reducers, effects, and selectors.

• Define actions to describe user events or interactions

• Create reducers to specify how state should change in response to actions

• Implement effects to manage side effects like API calls

• Use selectors to retrieve specific pieces of state for components

Stored procedures are precompiled SQL queries stored in the database, while functions are reusable code blocks that return a value.

• Stored procedures are used for performing specific tasks or operations on the database.

• Functions are used to encapsulate logic and can be called within SQL queries or other functions.

• Stored procedures can have input and output parameters, while functions always return a value.

• Stored procedu...read more

Model binder in MVC is used to map data from HTTP requests to action method parameters in controllers.

• Model binder maps form data, query string parameters, and route data to action method parameters in MVC controllers.

• It helps in simplifying the process of extracting data from HTTP requests.

• Model binder can be customized by creating custom model binders to handle complex data binding scenarios.

Yes, the transaction will be rolled back if the innermost stored procedure throws an error.

• If an error occurs in the innermost stored procedure, it will cause the entire transaction to be rolled back.

• This ensures that the database remains in a consistent state.

• Rolling back the transaction means that any changes made by the stored procedures within the transaction will be undone.

NgOnInit is a lifecycle hook in Angular that is called after the component has been initialized, while the constructor is a TypeScript feature used to initialize class properties.

• NgOnInit is specific to Angular components, while constructor is a general TypeScript feature.

• NgOnInit is used for initialization logic that relies on Angular's view and input bindings being initialized, while constructor is used for basic ini...read more

zone.js is a library for managing asynchronous operations in Angular applications.

• zone.js helps in tracking asynchronous operations and their execution context in Angular applications.

• It provides hooks for intercepting asynchronous tasks like setTimeout, setInterval, and promises.

• zone.js can be used for profiling, debugging, and error handling in Angular applications.

Use a query with GROUP BY and HAVING clause to identify and remove duplicates from a table.

• Use GROUP BY to group rows with the same values

• Use HAVING COUNT(*) > 1 to identify duplicates

• Use DELETE statement to remove duplicates

Program to reverse a string using array of characters

• Create a character array from the input string

• Use two pointers to swap characters from start and end of the array

• Continue swapping until the pointers meet in the middle
