⟩ Tell me how comfortable are you with writing HTML entirely by hand?
Although their resume may state that they're an HTML expert, often times many developers can't actually write an HTML document from top to bottom. They rely on an external publisher or have to constantly flip back to a reference manual. Any developer worth a damn should at least be able to write a simple HTML document without relying on external resources. A possible exercise is to draw up a fake website and ask them to write the HTML for it. Keep it simple and just make sure they have the basics down - watch for mistakes like forgetting the <head> </head> tags or serious misuse of certain elements. If they write something like: <image src="/some/image.gif">, it might be a good hint to wrap things up and call the next interviewee.
