MVC Interview Questions and Answers 2025

MVC Interview Questions and Answers For Freshers

Here, we have made a list of all the MVC interview questions that are most commonly asked during the interview process. 

1. What do you mean by MVC?

MVC stands for Model, View, and Controller

MVC, also known as Model View Controller, is a software design pattern that has this part where it breaks an operation into three major factors, i.e., the model, view, and controller.

This separation, in turn, is very important, as it helps to organize code in a way that makes it much more manageable.

The model has this part where it handles the operation’s data along with the business rules, and at the same time, also tries to define the structure of the data and manage the sense behind how the data is stored.

The view can principally be considered as what the user sees and communicates with. It's basically the user interface, which is substantially designed to present data from the model to cost or modernize data.

The controller can be considered as a proper point of connection between the model and the view, and tries to reuse user input. Along with this, it also tries to communicate with the model to cost or modernize data, and also determines which view should be displayed next.

2. According to you, what do filters mean in the context of MVC?

In the context of the MVC framework, controllers are where you define action styles, and generally, each action system corresponds directly to a specific UI control or user interaction.

Yet there are certain situations or circumstances where you might want to run some kind of sense before or after these major events take place, similar to logging or cleanup tasks.

ASP.NET MVC makes this easy in a way that allows you to hook into the action system lifecycle. With the functionality of certain built-in support for pre-action and post-action gestures, you can extend or modify what happens around your controller's conduct without cluttering the core sense.

3. What do you understand by DispatcherServlet?

The DispatcherServlet acts as the central entry point for incoming requests in a Spring MVC operation, and, along with this, it takes each request and routes it to the right element, no matter if it’s a controller, a view, or a model, based on how the operation is configured.

4. How do you navigate and maintain user sessions in an MVC operation?

There are mainly three ways through which you will be able to maintain the sessions of an MVC.

These are substantial

I. View Data,

II. Temp Data,

III. View Bag.

5. What do you mean by the MVC operation lifecycle?

There are two substantially important ways that every web operation abides by during the process of execution: 

- Processing the incoming request
- Returning the applicable response

This process is broken down into two main phases at the time of execution, which are

- Generating the request object
- Delivering the response back to the browser.

At the same time, there are four essential ways when it comes to building the request object

- Routing information is populated
- A request environment is created
- The correct route is linked

A case of the applicable regulator is initialized

This is one of the important MVC interview questions that can be very much expected during the interview process. 

6. What are some advantages of MVC?

Rapid multi-project development—Through the separation of responsibilities, different developers are able to work on the MVC simultaneously to speed up the development process. 

More convenient and easier maintenance—This separation is indeed very beneficial in a way that makes it much simpler to update or even debug specific parts of the application. 

SEO Friendly—MVC frameworks are also very beneficial in a way that they often promote SEO-friendly URLs, which improve the search engine optimization for various web applications. 

7. What do the following elements mean in the context of MVC: Presentation, Abstraction, Control?

Presentation—This substantially refers to how a particular conception or point is visually displayed to users within the operation.

Abstraction—This tries to represent the critical business sense or functionality that plays a major part when it comes to powering the operation behind the scenes.

Control—This acts as a bridge between the application’s logic and its visual output while also making sure that they stay in sync. Along with this, we must also note that it tries to navigate and manage the interactions with the other control elements within the system. 

8. How do you differentiate between these two terms: ‘ViewResult’ and ‘ActionResult’?

ViewResult is a class that extends the functionality of the AbstractResult class, and on the other hand, ActionResult serves as an abstract base class, which is designed to support the flexible return of different result types in a dynamic way. Some common classes that inherit from ActionResult are FileStreamResult, ViewResult, and JsonResult.

You must try and prepare this answer very thoroughly since this is also one of the important MVC interview questions. 

9. What do the beforeFilter() and afterFilter() functions mean in controllers?

The beforeFilter() system runs before any action within a controller is executed. It can be considered an ideal place to perform tasks such as verifying user permissions or checking if a session is still active.

On the other hand, afterFilter() is the final system that runs in the controller’s lifecycle, which is triggered after the controller action has finished and the view has been rendered.

10. What's Spring MVC?

- Spring MVC, also known as Spring Web MVC, is a Java-based framework that's designed specifically for developing flexible as well as justifiable web operations.

- It follows the Model-View-Controller (MVC) architectural pattern, which helps separate the operation's different enterprises and makes the development and testing easier.

- This framework is built on top of the critical features of the Spring Framework, such as dependency injection, inversion of control (IoC), and flawless integration with other technologies.

- One of the crucial elements of Spring MVC is the DispatcherServlet, which acts as the central controller and, at the same time, manages the inflow of requests and responses within the operation.

- By making effective use of Spring MVC, developers get a clear and well-structured way to develop web operations with certain applicable elements, which again is truly helpful when it comes to leading to smoother and further systematized codebases.

Now, let's discuss some MVC interview questions for the intermediate level

Intermediate-Level MVC Interview Questions and Answers

11. What's meant by MVC scaffolding?

Scaffolding in ASP.NET is a very useful feature that tries to streamline the development of web operations by automatically generating certain kinds of code.

Along with this, one further thing that we must flash back to is that Visual Studio comes with certain built-in scaffolding tools for both MVC as well as Web API systems, which makes it easier to set up the introductory structure of your operation without writing each thing from scratch.

Through the use of scaffolding, it's suitable to produce certain important canons that are demanded to work with your data models, in a way, helping you save time and reduce repetitive coding.

It also makes use of different templates, similar to runner templates, sludge templates, and reality templates, as well as field templates, which are also inclusively known as altar templates. These are helpful in a way that they help you to develop a completely functional and data-driven web operation with minimal homemade setup.

12. Which are the major folders that are included in an ASP.NET Core design when using the MVC template without areas?

When you try to produce an ASP.NET design through the MVC template (without enabling areas), the following folders are generally included by default: 

Controllers—This is where your operation’s controllers live. Each controller handles the incoming HTTP requests and also returns the responses, which are generally in the form of views or data.

Wwwroot—This is considered to be the root brochure for all the stationary lines (similar to CSS and JavaScript), and along with this, one further thing we must remember is that anything that we give in this folder is accessible directly through the browser.

Views—This folder holds the Razor view, which is substantially used to render the UI. It generally contains a subfolder for each of the controllers as well as a participant folder for views that are reused across multiple controllers or pages. 

This is also one of the expected MVC interview questions that you must try and prepare properly for. 

13. What do you understand by the conception of Razor in ASP.NET MVC

The use of view machines has long been supported by ASP.NET since these view machines are considered as modular factors, which indeed allows developers to use various types of template syntax when building their views.

One thing that you must keep in mind is that earlier the default view machine in ASP.NET MVC was dependent on the familiar .aspx, .ascx, and .master training formats, which again are analogous to those used in ASP.NET Web Forms.

As time passes, the other view machines, similar to Spark and Nhaml, are also gaining popularity among developers for their unique syntaxes and capabilities, and as MVC 3 was released, Microsoft introduced a new view machine, which is known as Razor, to bring about a more streamlined as well as a cleaner approach to writing various new templates.

14. What are the benefits of using an IoC (Inversion of Control) vessel in an operation?

There are actually many advantages of using an IOC vessel, which substantially include managing the lifecycle of objects so that developers don’t have to handle their creation or cleanup manually.

Along with this, it also makes it easier to swap out one implementation for another in the future without changing the code that depends on it. There are also two other important things that you must consider, such as 

I.  If there are any changes to a server’s dependencies, it won’t really directly have any impact on the parts of the app that use the specific service. 

II. The container can share a single example of a service across different, unrelated parts of the application, which can even improve the performance and also reduce the use of resources. 

This is also one of the important MVC interview questions that can be very much expected while you prepare for the interview process. 

15. What do you mean by GET and POST action types?

GET ACTION TYPE

This system is substantially used when you wish to recoup certain necessary data from a specific resource.

Along with this, a URL needs to be handed, and grounded on the script, it can also accept different voluntary parameters or overloads to upgrade the request.

POST ACTION TYPE

The POST system is used substantially to send data to a particular resource for processing, similar to when it comes to submitting a form or just uploading data.

Just like GET, it also needs a URL, but in addition, it includes data that needs to be reused. Analogous to GET, POST requests can support different overloads depending on what needs to be transferred.

Now we’ll discuss some MVC interview questions for the advanced level.

16. What's the database-first approach in MVC using Entity Framework?

The database-first approach is one of the ways to work with Entity Framework, alongside the code-first and model-first styles. In this approach, you start with an existing database, and Entity Framework automatically generates the necessary model classes and the DbContext grounded on that database structure. These generated classes represent your tables and connections, allowing the operation’s controllers to interact with the database smoothly. It is truly beneficial when you are doing your work with a pre-built or legacy database. 

17. What is your understanding of the major Razor syntax rules?

These are the important guidelines to follow when writing Razor syntax

- Razor code blocks are wrapped inside @{.}.
- To use inline C# expressions, simply start with the @ symbol.
- Every C# statement should end with a semicolon.
- Every C# statement should end with a semicolon and make use of the var keyword when you have to mention the variables. 
- Each of the text values (strings) should be closed in quotation marks.
- Razor follows C# rules, so it's case-sensitive—meaning Value and value are treated differently.
- Lines that use Razor syntax generally have the .cshtml file extension.

This type of question is very much expected for the MVC interview or MVC interview questions.

18. What's the database-first approach in MVC that makes use of the Entity Framework?

The database-first approach is one of the styles handled by Entity Framework, where development starts from an existing database rather than manually creating models or writing code to define the structure. 

Entity Framework automatically generates the model classes and DbContext based on the current database schema. These generated classes act as a ground between the database and your MVC operation's controllers, allowing smooth commerce with data without writing the data structure from scratch.

19. What is your way of applying Forms authentication in MVC?

 Authentication is the way of providing access to the user for a particular service by verifying his/her identity using his/her credentials, such as username and password or dispatch and password. It makes sure that the correct user is authenticated or logged in for a specific service, and the right service has been handed to the specific user based on their part. 

This is also one of the expected MVC interview questions. 

20. How is the JSON response returned from the Action method?

To return the JSON response action method, we need to return the JsonResult object. This object calls the JSON helper method. The given example returns a response in JSON format: 

public JsonResult sample()

{

string send = "hi";

return Json(send, JsonRequestBehavior.AllowGet);

}

Now that we have an understanding of some of the commonly asked MVC interview questions, let's go through some tips to prepare efficiently for the interview process. 

Tips to prepare for MVC interview questions 

Here we have discussed some simple tips that will surely guide you to prepare efficiently for the MVC interview questions.

I. You must be ready to prepare the core concepts very clearly

II. It is also important to emphasize the practical aspects of the MVC interview questions, such as writing code, as well as working on some basic tasks, such as controller methods and developing models. 

III. Try to have a very thorough understanding of the key MVC features, such as routing and the MVC request lifecycle. 

Thus, with these tips, you are sure to prepare your MVC interview questions smoothly and pass your interview successfully.
