How long are you interviews? How long are you watching the developer before you prod them to Google search? I like to think about a problem at least a little bit before giving up and asking for help. I have to at least be able to understand the problem before I can effectively find a solution. And hell, these days it's only a 50/50 shot whether searching will actually help with my problems or I'll just end up in a rabbit hole of SEO spam.
