While this appears to be a technical question on the surface, it is actually more of a cultural question. The difference is that technical questions address specific technologies used in website development, while cultural questions address general behaviors, beliefs, or methodologies developers use when creating their websites. You can expect both types of questions during the interview for this job.

"When developing back ends for websites, there are some informal guidelines most developers follow. DRY and DIE are two of these. DRY stands for Don't Repeat Yourself, and DIE means Duplication is Evil. While repeating or duplicating information on a website will not affect the website's functionality, doing this will impact the user experience. This may be fatal to the website's effectiveness if users decide not to visit it due to redundancy on the site. I try to follow these guidelines whenever I'm developing a back end for a website."
