The Video Interview Optimization Guide: 13 Technical Tricks to Look and Sound Perfect

Have you ever finished a video interview and cringed thinking about how you looked or sounded? That moment when you realize your lighting made you look like you were being interrogated, your audio cut out during your perfect answer, or your webcam angle gave everyone a great view of your nostrils?

You’re not alone. According to Withe, 82% of employers now use virtual interviews as part of their hiring process, and that number is only growing (source). But here’s the uncomfortable truth: those technical glitches aren’t just annoying—they’re actively hurting your chances of getting hired.

Research from Cognitive Research found that candidates with poor audio-visual quality in their video interviews received significantly lower ratings from hiring managers, even when their answers were identical to candidates with better technical setups (source). They called this the “AV quality bias,” and it affects everything from perceived competence to likability.

The good news? Most technical issues can be fixed with a few simple tweaks that don’t require expensive equipment. In this guide, you’ll discover 13 technical tricks that will dramatically improve how you look and sound in your next video interview—giving you the edge you need in today’s competitive job market.

Before the Interview: Technical Setup Essentials

Trick #1: The Perfect Camera Position

Nothing screams “unprofessional” faster than a webcam pointed up your nose or showing the top of your head. Camera positioning affects how interviewers perceive you at a psychological level.

Position your camera at or slightly above eye level. This creates a neutral, flattering angle that mimics in-person eye contact. If you’re using a laptop, place it on a stack of books or an adjustable stand to get the right height.

Your face should be centered in the frame with your eyes roughly one-third down from the top edge. Make sure there’s some space above your head and that your shoulders are visible in the shot.

Interview Guys Tip: The rule of thirds applies to video interviews! Position your eyes about one-third down from the top of the frame for the most professional and flattering composition. Research shows that proper eye contact significantly impacts how trustworthy you appear to interviewers (source).

Trick #2: Lighting Configuration That Flatters

Poor lighting can make you look tired, unprofessional, or simply hard to see. According to VidCruiter, lighting is the single most important factor that determines how good you look in a video interview (source).

The ideal setup uses three-point lighting:

1. Key light: Your main light source positioned in front and slightly to one side of your face
2. Fill light: A softer light on the opposite side to reduce shadows
3. Back light: A light behind you (pointed at your head/shoulders) to create separation from the background

Don’t have professional lighting equipment? No problem. Two desk lamps with daylight bulbs placed at 45-degree angles in front of you can work wonders. Or position yourself facing a window for natural light, with an additional lamp to fill in shadows.

Avoid backlighting (like sitting with a window behind you), overhead lighting that creates harsh shadows, and yellow-tinted bulbs that give your skin an unflattering color cast.

Trick #3: The Audio Quality Advantage

Crystal clear audio is non-negotiable in a video interview. Interviewers will forgive slightly lower video quality, but poor audio makes you sound unprofessional and creates actual comprehension issues.

Your built-in laptop microphone is rarely good enough. It picks up too much background noise and often sounds tinny or distant. Instead:

• Use an external USB microphone for the clearest sound (the Blue Snowball or Yeti are excellent affordable options)
• If you don’t have an external mic, use wired earbuds with a built-in microphone
• Position your microphone 6-8 inches from your mouth to avoid distortion
• Run a test recording before your interview to check sound quality

Interview Guys Tip: If you can’t invest in a dedicated microphone, the microphone on Apple AirPods or similar quality earbuds will sound significantly better than your laptop’s built-in mic. Just make sure to fully charge them before your interview!

Trick #4: The Stable Internet Connection Setup

Even the perfect lighting and crystal-clear audio won’t help if your connection keeps freezing. Research shows that 7 out of 10 candidates have missed job opportunities due to technical problems during video interviews (source).

To ensure a stable connection:

• Use a wired ethernet connection instead of WiFi whenever possible
• If you must use WiFi, position yourself close to your router
• Close all unnecessary applications and browser tabs to preserve bandwidth
• Ask others in your household to avoid streaming or large downloads during your interview
• Have your phone ready with a hotspot connection as backup if your primary internet fails

Test your internet speed at speedtest.net before your interview. For HD video calls, you’ll want at least 5 Mbps download and 3 Mbps upload speeds.

Environment Optimization

Trick #5: Creating the Perfect Background

Your background communicates almost as much about you as what you say. It’s an extension of your personal brand during the interview.

The best video interview backgrounds are:

• Clean and uncluttered
• Professional but with personality (a bookshelf, simple artwork, or plants work well)
• Not distracting (avoid busy patterns or movement in the background)

If your space doesn’t allow for an ideal background, use a virtual background—but choose one that looks realistic and professional. Solid neutral colors often work better than fake offices or landscapes.

Always do a test call to see exactly what will appear behind you. Remove anything inappropriate, overly personal, or distracting.

Trick #6: Room Acoustics Quick Fixes

Echoey audio makes you sound unprofessional and can make it difficult for interviewers to understand you. Hard surfaces reflect sound waves, creating that hollow, echoey quality many home video calls suffer from.

Quick fixes for better acoustics:

• Choose a carpeted room over rooms with hardwood or tile floors
• Add soft furnishings like curtains, rugs, or pillows to absorb sound
• Position yourself away from walls, especially bare ones
• Use a closet with clothes hanging as a makeshift recording booth if necessary
• If all else fails, drape a thick blanket over a standing rack behind your setup

Interview Guys Tip: Do the “clap test” in your chosen interview location. If you hear a sharp echo when you clap your hands, your audio will likely sound hollow during your interview. Add more soft materials to the room or choose a different location.

Trick #7: Distraction-Proofing Your Space

Nothing derails an interview faster than unexpected interruptions. According to the psychology of job interviews, maintaining focus is essential for demonstrating competence and interest.

To distraction-proof your space:

• Put a note on your door letting others know you’re in an interview
• Turn off all notifications on your computer and phone
• Secure pets in another room
• Choose the quietest time and location in your home
• Have water within reach but avoid other food or drinks that could spill

If you live with others, explicitly ask for uninterrupted time during your interview window. If you have children, try to schedule your interview during naptime or arrange for someone to watch them.

Trick #8: The Emergency Technical Kit

Even with perfect preparation, technical issues can still arise. Having an emergency kit ready can save your interview.

Your emergency technical kit should include:

• Backup earphones/headset
• Phone with hotspot capability (fully charged)
• Power bank for your devices
• Laptop charger plugged in, even if your battery is full
• Written connection details and interviewer contact information

If serious technical issues occur, stay calm and have a script ready: “I apologize for the technical difficulty. I’m going to reconnect using my backup solution. I’ll be back in just a moment.”

Software and Platform Mastery

Trick #9: Platform-Specific Optimizations

Each video platform has different settings and features that can dramatically improve your interview experience. Taking time to learn these before your interview gives you a significant advantage.

For the most common platforms:

Zoom:

• Enable “Touch up my appearance” in video settings
• Use “Original Sound” mode for better audio quality
• Test your audio and video through the settings menu before joining

Microsoft Teams:

• Use background blur rather than virtual backgrounds for more reliable performance
• Access advanced audio settings through the three-dot menu
• Familiarize yourself with the screen sharing options beforehand

Google Meet:

• Use the “Adjust video lighting” feature in settings
• Test your camera and microphone through the settings before joining
• Know where the noise cancellation feature is located

Practice with the specific platform at least a day before your interview. Nothing is worse than fumbling with unfamiliar controls while trying to make a good impression.

Trick #10: Video Enhancement Settings

Most people don’t realize that webcams have adjustable settings that can dramatically improve video quality. According to Tom’s Hardware, the right webcam settings can make even a basic camera look significantly better (source).

Key settings to adjust:

• Brightness and contrast: Increase slightly if your video appears dark
• Saturation: Adjust for the most natural skin tone
• Focus: Make sure auto-focus is enabled unless you’re using a high-end webcam
• Frame rate: Set to at least 30fps for smooth video
• Resolution: Use 720p minimum, 1080p if your connection supports it

Apps like Logitech Capture (for Logitech webcams) or general tools like ManyCam allow fine control over these settings. Always save your optimized settings once you’ve found the right balance.

Interview Guys Tip: Most webcams struggle with low light situations. If your video appears grainy, the simplest solution is almost always to add more light rather than adjusting camera settings. Even an additional desk lamp can make a dramatic difference in video quality.

Trick #11: Audio Processing Adjustments

Background noise can destroy an otherwise perfect interview. Modern video platforms include noise suppression features, but they need to be properly configured.

Audio enhancements to enable:

• Noise suppression: Reduces background sounds like fans or traffic
• Echo cancellation: Prevents your voice from creating feedback loops
• Auto gain control: Maintains consistent volume levels

If you’re using an external microphone, test different distance positions to find the sweet spot between clarity and natural tone. Speaking 6-8 inches away from most microphones gives the best results.

For those with more advanced setups, consider using free software like OBS Studio with plugins that can process your audio before it reaches your video platform.

Performance-Day Technical Strategies

Trick #12: The Pre-Interview Technical Checklist

The hour before your interview is crucial for technical preparation. Our interview anxiety elimination technique research shows that technical confidence significantly reduces overall interview stress.

Your 60-minute countdown should include:

1. 60 minutes before: Final equipment setup and connection test
2. 45 minutes before: Test call with a friend if possible
3. 30 minutes before: Restart your computer to clear any background processes
4. 15 minutes before: Connect to the meeting platform (but don’t join the call yet)
5. 10 minutes before: Final checks of audio, video, lighting, and background
6. 5 minutes before: Close all unnecessary applications and notifications
7. 2 minutes before: Take a deep breath, check your posture and camera framing

Having this structured countdown prevents last-minute panic and ensures you’ve covered all your technical bases before the interview begins.

Trick #13: Real-Time Technical Recovery Tactics

Even with perfect preparation, technical issues can still arise during your interview. How you handle them can actually demonstrate valuable workplace skills like problem-solving and grace under pressure.

When technical issues occur:

• Acknowledge the problem briefly and professionally: “I apologize for the technical difficulty. Let me fix that quickly.”
• Have prepared statements for common issues: “It seems my connection is unstable. I’m switching to my backup connection now.”
• Know how to quickly adjust settings without appearing flustered
• If completely disconnected, send a quick email to your interviewer while reconnecting

Always test your “plan B” options beforehand so you can switch to them smoothly if needed. This might include having your phone ready with the interview platform app installed.
