When developing a web application, do you prioritize SEO, maintainability, UX, performance, or security?

The interviewer will always ask some version of this question to determine your core competency as a web developer. Your response will also indicate which factors you prioritize when coding. For example, if you have experience in the finance industry, you may favor security over SEO. If you have developed an online e-commerce site, performance and SEO will be more important to you. Researching the organization and understanding its business model will give you a clue about which factors are more important and enable you to structure your answer appropriately.
