What are some of the biggest challenges you face as a web designer and how do you resolve them?
Software engineers can have a lot of job responsibilities. What do you focus on in addition to web development and design?
I think this answer varies a lot depending on how the structure of your team works. In some cases, the web developer might have large amounts of say in how the interface works, so they'll focus a lot of their attention and resources on figuring out the user. In others, a web developer might just be transforming a mock delivered by a designer who had already done all the prior research, so that developer might focus entirely on replicating that design with code. In any case, I'm sure someone in web development/design is always thinking of both the code design and the interface design. Where the focus lies depends on the context.
