Model: Represents the data and business logic of the application
View: Displays the data to the user and handles user input
Controller: Acts as an intermediary between the Model and View, handling user input and updating the Model and View accordingly

The interviewer was really cool. He realized that I mostly work on java applications so he chose to ask me stuff related to that.
