"Asking questions during a job interview is a way of showing engagement in the conversation and telegraphing your interest in the position," said Dorie Clark, author of "Entrepreneurial You." The key to asking questions that will impress is doing your research and listening. And don't ask questions that you can easily find online or to try and show off your knowledge. "I've had so many candidates ask questions trying to impress me with their smartness...they aren't listening. Ask questions to something you need to know to make a decision."
