Biting your lip
In an article for The Huffington Post, dentist Thomas P. Connelly revealed that biting your lower lip or inner cheeks is an anxious habit. Your interviewer might read this as a possible sign of deceit.
Changing your head position quickly
Moving your head rapidly when someone asks you a question indicates that you have something to hide, FBI consultant and body language expert Dr. Lillian Glass writes in her book "The Body Language of Liars."
Covering your mouth
This could indicate you're reluctant to answer a certain question, according to a LinkedIn post by investigative services provider Empire Investigations.
Being very still
If you come across as super stiff, that might look odd to the interviewer. Liars tend to overcompensate for their discomfort by being unusually still, according to an excerpt from "Warning Signs" by Anthony DeLorenzo and Dawn Ricci posted on Today.com.
Try to loosen up, like you would in a normal conversation.
Pointing when you talk
This defensive gesture can be perceived as rude and might also make your job interviewer feel like you're trying to deflect and avert suspicion, Glass previously told Business Insider.
Covering vulnerable body parts
Do you tend to move hands to your neck, throat, or chest while talking to people? If so, cut that out. It's a defensive mechanism that indicates you're feeling vulnerable, Glass writes in her book. It also might make it look like you have something to hide in your job interview.
Making too much or not enough eye contact
Bad liars tend to avoid too much eye contact. More experienced liars might overcompensate and stare with confidence, according to The Daily Mail's article on a University of Michigan study. Try to maintain normal eye contact during your job interview.
Having microexpressions
Maria Konnikova, author of "The Confidence Game: Why We Fall for It ... Every Time," previously told Business Insider that microexpressions are slight, hard-to-catch expressions that last only a fraction of as second. If your interviewer is quick enough to catch any negative microexpressions from you, they may start to wonder.
Having a fake smile
One of my favorite literary clichés ("his smile didn't reach his eyes" and other variations of the phrase) is actually quite relevant to the issue of coming across well in job interviews. If your interviewer sees that your eye muscles don't match your smile, they might catch onto your faking, as psychologist Erin Heerey told NBC.
Take it from Tyra Banks and learn to smile with your eyes too.
Putting an actual barrier between yourself and the interviewer
You put up your menu or purse on the table, in between you and your interviewer. By building an actual physical barrier, however small, you're distancing yourself from the person you're talking to, according to TED Talk speaker and author of "Liespotting: Proven Techniques to Detect Deception" Pamela Meyer. Your interviewer might see this as somewhat sketchy.
Taking shallow breaths
Heavy, shallow breathing is a sign that someone's lying to you, Glass previously told Business Insider. You may be nervous about your interview, but try to keep your breathing calm and even.
