If you're looking for a new job, here's a tip: have a firm handshake.
In a new study, scientists put 98 students through mock job interviews with businesspeople. The students also met with trained handshake raters who, unbeknownst to the students, rated their grips. Separately, the businesspeople graded each student's overall performance and hireability. The two group's scores were then compared.
Students who got high handshake marks were also rated most hireable.
"We've always heard that interviewers make up their mind about a person in the first two or three minutes of an interview, no matter how long the interview lasts," said study leader Greg Stewart, associate professor of management and organizations at the University of Iowa. "We found that the first impression begins with a handshake that sets the tone for the rest of the interview."
