Job trainers say when you walk through the door for an interview, you have about seven seconds to make a good first impression.
April Garner, a Career Resources Coordinator at Horry Georgetown Technical College, says non-verbal skills are essential in getting a job.
"Eye contact is very important. Eye contact can convey whether or not you are sincere or honest about a particular answer," says Garner.
Garner says what you do with your hands can tell an employer a lot about a person.
"Do not cross your arms. Crossing your arms can convey that you are kind of standoffish and unapproachable. Twisting of the hair conveys nervousness, playing with the lips and chin. Lots of different body language cues that employers will pick up on," says Garner.
Using small gestures is okay, but she says you shouldn't overdo it.
"People talk with their hands and their arms and they are waving them around like they are bringing in airplanes," Garner adds.
Mercedes Emilia says she's practicing keeping her hands under control to get ready for interviews.
"Probably the biggest things I have to work on is my hand movements, because I do move my hands a lot when I talk," she notes.
But before you even open your mouth, an employer can judge on looks alone.
"Candidates who are not dressed appropriately are the ones that they tend to shy away from," says Garner.
So dress for success, give a firm handshake and get to your interview early so you can have time to calm any nerves.
Another tip - stay calm! Try some breathing techniques before your interview. This helps you relax and lowers your blood pressure.
