Employers are risk averse with their hiring and so, in the absence of compelling evidence, they will choose to not hire a candidate. Pasting in an answer from somewhere else turns the question (and possibly the whole interview) into a no-op waste of everybody's time. It just doesn't provide the interviewer with good data to make a decision. My word of advice to you is this: study harder next time, be honest when they hit a gap in your knowledge (maybe they will offer to fill in that gap!), and don't Google on the phone. Interviews are like tests at school - closed book, unless stated otherwise.
