Technical Preparation: Eliminate All "Unexpected" Factors

Equipment Checklist

Camera

• Resolution at least 720p, 1080p recommended
• Test performance under different lighting
• Ensure camera position is at eye level (avoid looking down or up)

Microphone

• Built-in microphone works in quiet environments
• External microphone or noise-canceling headphones recommended
• Test audio quality in advance, ensure no echo or static

Network

• Wired network beats WiFi
• WiFi signal strength at least -50dBm
• Prepare mobile hotspot as backup
• Close other devices' network usage (downloads, streaming, etc.)

Software

• Install and test interview platform in advance (Zoom, Google Meet, etc.)
• Familiarize yourself with screen sharing, whiteboard features
• Prepare backup device (phone with same apps installed)

30-Minute Pre-Interview Check

1. Restart computer, close unnecessary apps
2. Test camera and microphone
3. Check network speed (recommend 20Mbps+ both ways)
4. Open interview link, confirm you can enter normally

Environment Setup: Create a Professional "Interview Room"

Background Selection

Best choices: Solid color wall or clean bookshelf

• White, beige, or light gray are safest
• Bookshelf can show professional image, but must be tidy and organized

Avoid:

• Cluttered rooms
• Strong light sources behind you (like windows)
• People walking in background
• Mirrors (cause reflections and visual distraction)

Lighting Setup

Ideal setup: Soft frontal light

• Natural light best: sit facing a window
• No natural light: use ring light or desk lamp, light source directly behind camera

Avoid:

• Backlight (makes face dark)
• Overhead light (creates shadows under eyes)
• Side light (makes half the face too bright)

Sound Control

• Close windows to reduce external noise
• Inform family/roommates not to disturb
• Turn off phone notifications or set to silent
• If environment is noisy, use noise-canceling headphones

On-Camera Presence: Show Professionalism and Confidence

Eye Contact

Key technique: Look at the camera, not the screen

Many people habitually look at the person on screen while talking, making you appear to be "looking down" or "looking elsewhere" to the other party.

Practice method:

• Place a small marker near the camera to remind yourself to look there
• Record yourself speaking, check if eye contact looks natural

Body Language

Posture

• Sit straight, but not rigid
• Maintain 50-70cm distance from camera
• Show upper body on screen (above chest)

Gestures

• Use gestures moderately to add expressiveness
• Avoid excessive small movements (pen clicking, face touching)
• Keep gestures within camera view

Attire Recommendations

Principle: Take it as seriously as an in-person interview

• Top: Dress shirt or business casual
• Bottom: Though rarely shown, wearing formal helps maintain your state
• Color: Avoid pure white (too bright) or fine stripes (causes moiré pattern)
• Avoid: Too casual T-shirts, hoodies

Handling Unexpected Issues: Turn Crisis into Opportunity

Common Problems and Solutions

Network Lag

• Immediately inform interviewer: "Sorry, the network seems unstable"
• Turn off camera (keep audio), reduce bandwidth usage
• If lag persists, request switching to phone interview

Equipment Failure

• Stay calm, don't panic
• Quickly switch to backup device (phone)
• If can't resolve quickly, request rescheduling

Unexpected Interruptions

• Family member walks in: Stay professional, briefly apologize and continue
• External noise: Pause speaking, wait for noise to pass
• Emergency: Be honest, request brief pause

Proactive Communication

When problems arise, proactively informing is better than waiting:

"Sorry, I'm experiencing a technical issue. May I have a minute to resolve it?"

Most interviewers will understand and give you time.

Unique Advantages of Remote Interviews

While remote interviews have challenges, they also offer unique benefits:

Auxiliary Tools You Can Use

• Notes and prepared question lists
• Code snippet references (if open-book interview)
• Company materials and interviewer background info

More Comfortable Environment

• Easier to relax in familiar surroundings
• Can use your own equipment (keyboard, mouse)
• No commute, maintain peak condition
