Which of the following is NOT mentioned as a help in interviews?

(11) As any serious job-hunter knows, it helps to dress smartly and smile at that all-important interview. But research has revealed that a finn handshake is what really matters when it comes to impressing potential employers. Although previous studies have shown a "wet fish" handshake indicates shyness, and a firm "pump" confidence, there has been little evidence about the effect this has on an interviewer.
    (12) The U. S. research looked at 98 undergraduates taking part in mock interviews with businesses. As each was graded on their overall performance, five " handshake raters" also marked them on their grip, strength, duration, vigour and eye contact. Professor Greg Stewart, from the University of Iowa, who led the study, said those who scored highly with the handshake raters were also considered to be the most hireable by the interviewers. The study, published in the Journal of Applied Psychology, also found women with a firm handshake were likely to be evaluated more favorably than their male counterparts. Women were less likely to have a highly rated handshake, partly because traditionally they shake hands less than men. (13) But when women did possess a firm handshake, they were likely to be evaluated more favorably than their male counterparts.
