When the interviewer is listening to you intently — and seems genuinely interested in what you have to say — that's a good indication you're on the right track.
To figure out whether they're enjoying the conversation, pay careful attention to the interviewer's body language.
"Actions speak louder than words," says Debra DelBelso, director of the Career Center at Siena College. It's always a good sign when the interviewer smiles, maintains eye contact, and leans in toward you while you speak, she explains.
Matthew Randall, executive director of the Center for Professional Excellence at York College of Pennsylvania, says one good way to decide if the interviewer is being genuine or just polite is to pay close attention to their grin.
"Any professional will likely conduct him or herself with good decorum regardless of what they think of you," he says. "To try to determine if the smile is authentic, 'Duchenne' smiles include the narrowing or partial closure of the eyes and accentuated crows feet around the eyes."
