What the Experts Say
“Informational interviews are essential to helping you find out more about the type of industry, company, or role you’re interested in,” says Dorie Clark, author of Stand Out Networking. “You may think you already know all about a certain position, but speaking to someone directly gives you the opportunity to test your assumptions.” John Lees, a UK-based career strategist and author of The Success Code, agrees.
