To crack the most challenging interviews, you should practice the following important MVC interview questions with answers.
MVC stands for Model View Controller. You can use a software architecture pattern for effective web application development. In an MVC application, the components are:
This is one of the most commonly asked MVC interview questions. You must consider the following benefits while answering this question:
The role of different MVC components is as follows:
Controllers form an integral part of MVC interview questions. The return types of controller action methods are:
You should be well aware of the limitations of the MVC model to answer such MVC interview questions. Here are some major drawbacks of the MVC model:
A web application primarily has two execution steps:
The same applies to MVC applications that have two main phases –creating the request object and sending the response to the browser. There are four basic steps to create the request object:
Step 1: Fill route
Step 2: Fetch the route
Step 3: Create a request context
Step 4: Create a controller instance.
The sessions are maintained in three possible ways:
There are three types of views in MVC:
A partial view is a portion of HTML carefully injected into an existing DOM. It is commonly implemented for componentizing Razor views. It makes them simpler to build and update. A controller method can also return the partial view directly.
This is one of the frequently asked basic MVC interview questions. There are three logical layers of MVC:
You can apply ActionFilters to a controller action or an entire controller for executing the logic while the MVC action is executed. It permits the implementation of pre and post-processing logic and action methods.
This is one of the critical MVC interview questions that checks your basic understanding of the execution steps. You must elaborate on the following steps for executing an MVC project:
Take a look at some Spring MVC Interview Questions to prepare better.
You must go through the following MVC interview questions and answers for experienced developers to nail interviews for senior MVC programmer positions.
MVC routing is a pattern-matching scheme. You can use it for incoming mapping requests of browsers to a definite MVC controller action. The three important segments for routing are as follows:
MVC routes govern which controller method will be executed for a given URL. The properties of MVC routes are:
The RouteCollection in MVC has a set of routes responsible for registering the routes in the application. The RegisterRoutes method helps record the routes in the collection. A route defines the URL pattern and a handler which checks the request matching the pattern.
The MVC routing consists of three parameters. The first parameter provides the name of the route. The second determines a specific pattern with which the URL matches and the third parameter provides default values for its placeholders.
Ajax implementation forms an integral part of MVC interview questions. Here are the following two approaches to implementing Ajax in MVC.
The following table enumerates the differences between ActionResult and ViewResult:
It is an abstract class, i.e., it has methods and variables without the implementation body of instruction.
It is derived from an abstract class.
It is best if you want to derive different types of views dynamically.
It is not so effective if you wish to derive different types of views dynamically.
It has several derived classes like JsonResult, ViewResult, and FileStreamResult.
It does not have its own derived class.
The major steps that define the page life cycle are as follows:
Spring MVC is one of the most important topics for MVC interview questions, and the interviewer might put up several questions related to Spring MVC. The sample questions section will provide some important MVC interview questions.
Spring MVC is a Java-based framework that provides a Model View Controller architecture in the application in addition to ready components implemented for developing adaptable web applications. It utilizes all the elementary traits of a core Spring Framework such as dependency injection, integration with other frameworks, lightweight, inversion of control, and more. Spring MVC uses DispatcherServlet to implement MVC in Spring Framework.
If you are preparing for senior positions, you must practice the following MVC interview questions on scaffolding, error handling, and other vital topics.
The filter order will be as follows if you implement multiple filters:
You can use exception handling to deal with MVC errors, whether it is a Windows Forms application or a web application.
The HandleError attribute helps in providing built-in exception filters and is functional over the action method and controller at its global level. You can override the "OnException" event in the controller. You can set the "Result" to the view name you want to invoke when an error occurs.
Scaffolding is an ASP.NET code-generation framework for web applications. You can use it to develop MVC applications to rapidly enhance the code that intermingles with the application's data model. It can reduce the quantity of time for developing a standard data operation in the web application.
Razor View engine is a markup syntax that helps you write HTML and server-side code in web pages using C# or VB.NET.
The file extensions for razor views are:
RenderBody is a ContentPlaceHolder of web forms available on the layout page. It is responsible for rendering the child pages/views. The layout page has a single RenderBody() method, while multiple RenderPage() can reside within the layout page.
This completes the list of important MVC interview questions that will uplevel your next tech interview prep.
Q1. What are the important skills required to ace MVC interview questions?
You should be proficient in C#, Visual Basic, .NET, ASP.NET MVC applications. Your knowledge of Entity Framework ADO.NET can also give you an upper hand in the interviews. Top tech companies seek MSSQL, MySQL, Oracle, and other RDBMS expertise. You must check out the official job description for specific skills that the position demands.
Q2. How do I prepare for MVC interview questions?
You must focus on the most important topics such as ASP.NET and Spring Framework, Razor View Engine, ViewData, ViewBag, TempData and practice answering the most anticipated MVC interview questions on them. You can also enroll in mock interviews to learn how to answer the most challenging MVC interview questions and get experts' guidance.
Q3. Which programming language is best for solving coding MVC interview questions?
The default language used in MVC is C#. However, you can use your own specific programming languages, including Ruby on Rails, .NET, Java, amongst others, for solving MVC interview questions.
Q4. Which client-side frameworks are important for MVC interviews?
You should be familiar with the popular client-side frameworks such as jQuery, Angular, and React. You must check out the official job description to check if the company has specified some framework or version in particular.
Q5. Is having a master's degree essential to crack MVC developer interviews?
You can work as an MVC developer even with a bachelor's degree and upgrade your skills. However, for better career prospects, having a master's degree may be useful.
To crack the most challenging MVC interviews, you must demonstrate your problem-solving, solution design, and high-quality coding skills. Preparing strategically for technical interviews, especially the challenging ones, steers you on the path to becoming a better software professional with improved skills.
