Advice about interview body language often tips into vague pseudo-science — precise claims about exactly how many seconds of eye contact convey confidence, or what a specific hand gesture supposedly reveals. Most of that is overstated. What's genuinely true, and useful, is simpler: nervous body language is common, some of it is distracting enough to compete with your actual answers for attention, and a handful of specific, practical adjustments help more than trying to consciously control every movement.

The goal isn't to perform confidence — it's to remove distractions

Trying to actively project confidence through posture and gesture usually reads as stiff or performative, especially on video. A more reliable goal: reduce the specific habits that pull attention away from what you're saying, so your actual answer is what the interviewer remembers, not a distracting tic.

On video calls specifically

Look at the camera, not the screen, when delivering a key point. Looking at the person's face on screen feels natural but reads as slightly off-camera to them; looking directly at the camera lens during your most important sentences approximates eye contact much more closely, even though it feels unnatural to you while doing it.

Frame yourself so your hands are visible if you gesture naturally. A frame that's too tight, showing only your face, can make natural gestures look like off-screen fidgeting. This is a small technical fix — sit back slightly — that removes a distraction you might not even know you're creating.

Check your lighting and background once, not every time. A cluttered or poorly lit background pulls attention in the first thirty seconds, then usually fades — but a distraction that repeats (a device or notification visible behind you, a light causing glare) keeps pulling focus throughout.

In person

Sit back, not rigidly upright. Leaning slightly forward when actively listening or making a key point, then returning to a relaxed, upright posture, reads as more natural than holding one stiff position for the entire interview.

Keep your hands visible and let them move naturally when you talk. Hiding your hands (crossed arms, hands under the table) can read as closed off, even unintentionally; forcing exaggerated gestures reads as performed. The natural middle ground — hands visible, moving normally as you'd gesture in any comfortable conversation — usually happens on its own once you stop actively thinking about it.

Match the room's energy, not a fixed script. A relaxed, conversational interviewer usually responds better to a genuinely relaxed match in tone; a more formal, fast-paced interviewer usually responds better to a slightly more measured, direct style. Rigidly performing "confident body language" regardless of the room's actual tone can read as tone-deaf.

The single most common distracting habit

Filler words and verbal pacing matter as much as physical body language, and they're often the actual source of a "nervous" impression more than posture is. Speaking slightly slower than feels natural, and allowing a short pause before answering instead of filling every silence with "um" or an immediate half-formed answer, does more for a composed impression than any specific posture adjustment.

Practice reduces this more than technique does

Most nervous body language fades on its own once the content of your answer is well-rehearsed enough that you're not simultaneously composing the answer and worrying about how you look. Practicing your answers out loud — ideally recording yourself once, even though it's uncomfortable to watch back — surfaces your own specific habits far more effectively than generic advice about posture ever will. Our Interview Prep Generator and guide on preparing for behavioral interview questions both help you get to that level of rehearsed comfort with the content, which does more for your presence than posture coaching alone.

The honest bottom line

Body language matters at the margins — it can add or subtract polish — but it rarely overrides the substance of your answers. Spending most of your preparation time on content, with a smaller amount on removing your own specific distracting habits, is a better use of limited prep time than memorizing generic gesture advice.
