I expect my interviewees to use Google and am disappointed if they don't. It's more important to me that they know how to find the right answer than it is that they just know it off the top of their head. 90% of their time is going to be spent figuring out how to solve all the known-unknowns they're going to come across.
Yup! If I see them struggling to answer a question or admit to not knowing something I will ask them "well, how would you find the answer?", to which they always half-jokingly answer "I'd Google it". That's when I'll let them know that I want to see some of that too!
Because people administering tests always have weird or arbitrary assumptions and restrictions. Part of getting through school is jumping through all the contrived hoops they place before you, even when it'd be much easier to just walk around the hoops. Job interviews are no different; different interviewers have different expectations, and many don't want you consulting outside information sources.
Ditto, 20 years on and I research and read articles when I start any new project because in one year there can be entire paradigm shifts in tooling and best practices.
