A recruiting company approached me after obtaining my résumé online. I went through an initial interview with them, at which point they passed my information on to the company.

The company conducted a phone interview, and afterward I was asked to fill out some information (background check, drug screening, etc.) and fax or deliver them to the recruiting company.

After those cleared, I was asked to come in for an in-person interview. I worked through a technical discussion, with a current developer there, about the projects I would be undertaking. He asked me detail-oriented questions about procedures, code, and practices. After that, I was asked about my expectations for the position, and then asked what I thought was expected of me. We then discussed details, and I was told I could take a tour of the facilities before leaving.

I was almost certain that I wasn't going to get the position, as it was very competitive. However, I received the official job offer later that afternoon via phone call, and reported the following week for work.

Could you please describe the full MVC architecture and how you would go about making a change within the structure of a website?
