Something as simple as glancing at your watch or holding eye contact for too long can throw off your interviewer and hurt your chances of landing the job.
Same goes for gesturing wildly or fiddling with your keys in your pocket. Depending on what you do with your hands, you can give the impression of confidence, nervousness, or even dishonesty.
In their book "Crazy Good Interviewing," John B. Molidor, Ph.D., and Barbara Parus outline what different hand motions might convey. We combined Molidor and Parus's ideas with research from other experts to give you a handy (pardon the pun) breakdown to consult before your next interview.
