MVC Interview Questions: Before We Start
The Model-View-Controller (MVC) is a framework – a software architectural pattern commonly used to separate an application into three main logical and interconnected components which are Model, View, and Controller.
This is done to separate internal representations of information from the ways information is presented to and accepted by the user. Each component is built to handle specific development aspects of an application.
The MVC separates the business logic and presentation layer from each other. Nowadays, MVC architecture in web technology has become popular for designing web applications as well as mobile apps.
Applying for a web development position, need a refresher on MVC and tips to answer MVC interview questions? You are at the right place.
Most Common MVC Interview Questions & Answers
1. Explain MVC’s Features in a Simple Way
MVC interview questions usually start off simple, and here’s how to answer the question:
“MVC provides easy and frictionless testability. This framework is highly testable, extensible, and pluggable. It also offers full control of our HTML and URLs for better configuration.
Other features include leveraging existing features provided by ASP.NET, JSP, Django, etc, having a clear separation of logic: Model, View, Controller and application tasks via business logic, Ul logic, and input logic.
Not to forget, it offers URL Routing for SEO Friendly URLs, powerful URL mapping for comprehensible and searchable URLs, and it supports Test Driven Development (TDD). In my previous companies, we take pride in utilising this framework as best as we could.
2. What are the advantages of MVC? Why is it crucial?
As the interview progresses, MVC interview questions tend to move in the direction of “why”. Here’s a simple sample answer for you to refresh and refer to:
“It’s simple. MVC segregate projects into different segments, making it easy, organised and systematic for developers to work on because we are able to edit parts of the project separately, benefitting the team from lesser development and maintenance cost.
Since MVC has a clear separation between business logic and presentation logic, each MVC object has different responsibilities – i.e. all classes and objects are independent of one another so development progress can be done in parallel.”
Try to provide examples of MVC benefits in your previous projects. Giving specific examples would make you even more credible in the employers’ eyes.
3. What are the differences between View and Partial View in MVC?
Interviewers may want to test the extent of your technical knowledge, so we’ve prepared this summary for you:
- View contains the layout page; Partial View does not
- View is not as lightweight as Partial View
- View may contain markup tags; Partial View does not because it was designed to render within the view
- The Viewstart page is rendered before any View is rendered; Partial View does not very for a Viewstart
- And more of your own understanding
4. We Use PHP MVC Frameworks. What Do You Think About It?
It’s time for you to prove your expertise and match your profile closer to what the company is looking for. Sample answer:
“PHP MVC Framework is awesome because it simplifies working with complex technologies by hiding all the complex implementation details while providing all the standard professional coding methods that we can use to build our applications.
As a result, PHP MVC frameworks increase my team’s productivity because the base activities such as connecting to the database and sanitising user input are already partially implemented.”
Try to be objective and critical when answering MVC interview questions by weighing the pros & cons, as well as providing relevant examples.
5. Any Important Things to Note When Creating an MVC App?
When answering MVC interview questions, try making your points relevant by relating them to your previous/current work experience to showcase your expertise.
Sample answer:
“Throughout my years of experience developing web applications, there are some important learnings that I have remembered while creating an MVC application these days.
In the beginning, I quickly learned that ASP.net MVC should not be a replacement for ASP.Net web forms-based applications. Also, the way we approach any MVC app development should be decided based on the application requirements and features provided by ASP.net MVC to suit the specific development needs.
Next, most if not all of the time, the application development process with ASP.NET MVC is usually more complex compared to web forms-based applications. Last but not least, application maintainability is always higher with the separation of the application tasks.
Learning never stops, so I’m always curious to pick up new points when using MVC for web development and I will share my knowledge with all my team members so we can all be better together.”
Final Remarks
Answering such technical interview questions is not easy, but definitely necessary if you are answering MVC interview questions as a web developer. That said, we hope that we have refreshed your memories about MVC and provided useful advice for you to ace the MVC interview questions.
