Phone Interview vs Video Interview: How to Prepare for Each

Key Differences: What Each Format Tests

Phone and video interviews are not simply the same conversation conducted through different technology. They emphasize different communication skills and create different assessment conditions.

How to Prepare for a Phone Interview

Environment and Setup

Choose a location where you can guarantee quiet for the full duration of the call. This sounds obvious but is consistently underestimated. Background noise — traffic, children, coffee shop ambient sound — creates a negative impression immediately and distracts both you and the interviewer. Find a private space, close the door, and do a test call to check your signal strength at least the day before.

Use a headset or earbuds rather than speakerphone. The audio quality is consistently better, your voice sounds more present and confident, and you free up both hands to reference notes if needed.

Using Notes Effectively

The invisible format of a phone interview means you can have your materials in front of you — but this only helps if you use them correctly. Print or display your top 3–4 bullet points for your Tell me about yourself answer, your key STAR stories, and the most important things you want to communicate about your fit for the role.

Do not read from your notes. Candidates who read from scripts sound robotic and unnatural, which creates a worse impression than a slightly imperfect but genuine answer. Notes should be prompts — reminders of your key points — not scripts. If you need to read something, you have not prepared enough.

Voice Projection and Pacing

On phone, your voice is your entire first impression. Slow down by about 10–15% from your normal conversational pace — people naturally speak too fast when nervous, and the phone format amplifies pace more than video does. Use pauses deliberately: a brief pause before answering a question signals that you are thinking, not scrambling. Smile while you speak — it physically changes your vocal tone in a way the interviewer can hear, even if they cannot see you.

Common Phone Interview Mistakes

• Answering too quickly. There is no visual cue that you have finished thinking. Take a moment before answering. A three-second pause feels longer to you than to the interviewer.
• Walking around while talking. Movement affects your breathing and vocal consistency. Sit still.
• Multitasking. The interviewer can often tell if you are doing something else. Give the call your full, undivided attention.
• Forgetting to confirm follow-up logistics. At the end of the call, confirm the next steps — timeline, format of the next round, who you will hear from.

How to Prepare for a Video Interview

Technical Setup: Do This the Day Before

Never leave technical setup for the day of the interview. Murphy's Law is most reliably violated in the thirty minutes before you need your camera to work. Run through the full setup at least 24 hours in advance:

• Camera: Position it at or slightly above eye level. A camera below eye level creates an unflattering up-the-nose angle. Stack books under your laptop if needed.
• Lighting: Position a light source in front of you, not behind you. A window with natural light is ideal; a simple ring light or desk lamp aimed at your face works equally well. A light behind you creates a silhouette effect.
• Background: Clean and neutral. A plain wall, a tidy bookshelf, or a professional virtual background are all acceptable. A cluttered background — unmade bed, piles of laundry, kitchen mess — is a distraction and a negative signal.
• Audio: Test your microphone. Built-in laptop microphones are often acceptable, but a headset or USB microphone significantly improves audio quality. Test the room for echo — bare walls and floors echo more than rooms with soft furnishings.
• Internet: If possible, use a wired connection rather than wifi during the interview. Close other bandwidth-intensive applications — streaming, large downloads — before the call starts.

Eye Contact on Camera

The most common and most damaging mistake in video interviews is looking at the interviewer's face on your screen rather than at your camera. When you look at the screen, you appear to be looking slightly downward from the interviewer's perspective — which reads as lack of eye contact and disengagement.

Train yourself to look at the camera lens, not at the face on screen. This is uncomfortable at first because you cannot see the other person's reactions, but it is what creates the impression of direct eye contact on the other end. Practice this in video calls with friends before your interview.

Non-Verbal Communication on Video

Video interviews compress your body language into a head-and-shoulders frame. This means facial expression and posture carry more weight than they do in person. Sit upright — not rigid, but engaged. Nod occasionally to signal that you are following. Avoid touching your face, which reads as nervousness on screen. Lean in slightly when making an important point; it creates a sense of engagement.

Be aware of your default facial expression when listening. Many people have a neutral expression that reads as stern or skeptical. Practice in front of a mirror or on camera to understand what your listening face looks like and adjust if needed.

Common Video Interview Mistakes

• Joining the call late. Log in 3–5 minutes early. Technical issues happen and a late join creates a poor first impression that you spend the rest of the interview overcoming.
• Wearing casual clothing because it is remote. Dress as you would for an in-person interview. The camera does not make clothing irrelevant — what you wear visually communicates how seriously you are taking the opportunity.
• Not having a backup plan for technical failures. Have the interviewer's phone number available before the call starts. If the video connection fails, you can immediately switch to phone rather than scrambling to find their contact details.
• Checking notifications during the call. Turn off notifications on all your devices before you join. A notification sound mid-answer is distracting to both parties and signals that your attention is divided.

Universal Tips for Both Formats

Regardless of format, the fundamentals of interview performance remain the same: know your STAR stories, research the company and role thoroughly, have thoughtful questions ready, and practice answering common questions aloud before the interview. Neither format will compensate for inadequate content preparation — and neither will punish strong content delivered clearly.

Tools like InterviewAce work across both phone and video formats because they listen to the audio of your interview in real time and surface relevant answer suggestions from your background. For phone interviews, you can use it as an additional resource alongside your printed notes. For video interviews, position it on a secondary screen or in a corner of your primary screen where you can glance at it without obviously looking away from the camera.

Both phone and video interviews are screen tests for your actual interview performance — they are designed to filter candidates before the more time-intensive in-person or final rounds. Treat them with the same seriousness as the final round. Many candidates lose opportunities they should have won because they treated a phone screen as too casual to warrant full preparation.

The candidates who consistently advance through screening rounds are those who take the format seriously and prepare for its specific demands. You now know exactly what those demands are — for both.
