Explain important considerations to keep in mind when deciding whether to conduct an interview face-to-face or via email.

Face-to-face interviews give you the opportunity to gauge the reaction to your questions and observe the nonverbal signals that accompany the answers,but email interviews are becoming more common,partly because they give subjects a chance to think through their responses thoroughly rather than rushing to fit the time constraints of a face-to-face interview.Also,email interviews might be the only way you will be able to access some experts.
