The MVC typically helps you to organize web application into a well-structured pattern. This makes it a lot easier to maintain code and is well-known by developers.

Popular MVCs are as follows:

☛ AngularJS

☛ Backbone.js

For this question, what you’re really trying to find out has nothing to do with whether they have used an MVC, but rather their preference and level of experience with it. If the candidate is able to articulate why they prefer one over the other, you’ll know that they’re engaged in what they do and care about the tools that they use.

Why is this important?

It’s important as you have to be able to trust your front-end developer to keep up to date with new and relevant technologies. They should also have a clear idea about what should be used and when it should be used.
