⟩ Explain me how do you take into account SEO, maintainability, UX, performance, and security when you’re building a web application?
This is a biggie. The ability to balance and understand these very different factors is a core competency for any web developer. Their response will also indicate which factors they will prioritize when coding. For example, if you are a large financial institution, you may favor security over SEO. If you are an online publication, performance and SEO will be more important for your type of work.
