I've never googled something in an interview (typically for the face-to-face part I'm not at a computer so that would be difficult, and googling under pressure seems like a bad idea).

But I have told interviews that I don't know, but I'd google it if I needed to in a work situation, and that's always been received positively. I guess it depends on what they're asking about though. Some stuff you should know off the top of your head...
