Online Interview Preparation: The A-Z Checklist
Ezlun Team4 min read
Online interviews have become the standard for recruitment since the pandemic. Over 60% of initial interview rounds now take place via video calls (Zoom, Google Meet, Microsoft Teams). However, many candidates still make basic technical and presentation errors that significantly diminish their impression. This article provides a comprehensive checklist to help you prepare for a professional online interview.
How do online interviews differ from in-person ones?
**Limited non-verbal communication:** Only your face and shoulders are visible, not your full body.
**Difficult eye contact:** You need to look at the camera, not the screen.
**Technical issues:** Internet lag, faulty microphone, non-functional camera.
**Easily distracted:** Noise, family members, pets.
**Hard to read reactions:** It's difficult to tell if the interviewer is nodding in agreement or frowning.
Equipment Checklist (check 1 hour before)
Camera
Webcam working, at eye level (not looking up from below).
Clear image quality, not blurry.
Use a laptop with a good camera or an external webcam.
Avoid using a phone unless there's no other option.
Microphone
Test your mic beforehand using a recording app.
Use headphones with a mic (AirPods, wired headphones) – sound is clearer than a laptop mic.
Turn off all notification sounds on your device.
Internet
Use a wired connection if possible (more stable than WiFi).
Minimum speed: 5Mbps upload.
Close bandwidth-intensive applications (torrent, cloud sync, streaming).
Prepare a 4G hotspot as a backup.
Software
Install Zoom/Google Meet/Teams at least one day in advance.
Update to the latest version.
Test joining a meeting with a trial link.
Log in with your real name, not a nickname.
Set Up Your Interview Space
Background
Clean, simple background: white wall, tidy bookshelf.
No clutter, clothes drying, or unmade beds.
If you don't have a suitable background, use a solid-color virtual background (avoid beach or space images).
Lighting
Light source should be IN FRONT of you (not behind you).
Natural light from a window is best.
If it's dark, use a desk lamp or ring light.
Avoid overhead lighting (creates shadows on your face).
Sound
Closed room, avoid noise.
Inform family members not to disturb you.
Turn off your doorbell if possible.
Close windows if near a busy street.
Attire
Dress **completely** as you would for an in-person interview (including pants).
Business casual or more formal: button-down shirt, collared polo shirt.
Avoid small patterns, stripes (can cause distortion on camera).
Solid colors (white, navy blue, grey) work best on camera.
Body Language on Camera
Eye Contact
**Look at the camera when speaking**, not at the interviewer's face on the screen.
Place a small note next to the camera: "Look here."
When listening, you can look at the screen (more natural).
Expressions
Nod gently when listening (shows you're paying attention).
Smile naturally.
Avoid a poker face – it can appear colder on camera than in reality.
Posture
Sit up straight, shoulders relaxed.
Hands on the table, within the camera frame.
Do not cross your arms or lean back.
Handling Technical Issues
Internet Lag
"I apologize, my connection seems unstable. I'll turn off my camera to improve the audio."
If severe: "Please give me a minute to switch to my 4G hotspot."
Cannot Hear Clearly
"Excuse me, I didn't quite catch the last part. Could you please repeat that?"
Stay calm, don't panic.
Software Crash
Have the HR's phone number ready to text them.
Rejoin immediately.
Keep it brief: "Apologies for the technical issue. I'm ready to continue."
After the Interview
Send a **thank you email** within 24 hours.
Content: express gratitude + reiterate 1-2 impressive points from the interview + reaffirm your interest.
