You bought a ring light. You tested the connection. You positioned the camera at eye level and made the background look professional. You did everything right.
The format can still work against you.
In a randomized study of 114 participants, candidates interviewed over Skype received lower live performance ratings than candidates interviewed face to face. Differences in perceived eye contact, impression management, and social presence helped explain the gap.
Zoom is now the familiar name for this format. The experiment itself used Skype.
This was a controlled student simulation, not proof that every video applicant is penalized in every real hiring process or that better technology cannot help.
What the researchers tested
Participants were randomly assigned to a face-to-face or videoconference interview. Trained interviewers asked the same 13 structured questions in both conditions.
The candidates were university students applying in a simulated selection process. The video interviews used Skype and the participants' own internet connections.
What they found
Live interviewers rated face-to-face candidates at 3.96 on average and video candidates at 3.78. The standardized difference was d = .43, a small-to-moderate effect, and was statistically significant.
The researchers also had independent raters evaluate recordings. Their average rating was 3.86 for face-to-face interviews and 3.75 for video interviews. That smaller difference (d = .27) did not meet the conventional threshold for statistical significance (p = .06).
Across the two rating sources, the combined mode difference was d = .39.
What may explain the gap
Candidates rated the quality of eye contact much lower in video interviews, with a large standardized difference (d = 1.21). Interviewers also saw an eye-contact difference (d = .64).
Video candidates reported less effective impression management (d = .48) and lower social presence (d = .42). Statistical analyses indicated that these factors helped account for the performance-rating difference.
The design supports a problem with the interaction, not the claim that “physics makes eye contact impossible” or that better technology cannot help. Participants used the video tools and connections available in the study. The experiment did not compare modern eye-contact correction, different camera placements, or every video platform.
How to prepare for video
Practise in the actual format
Record answers through the camera and connection you plan to use. Check delay, framing, sound, and where your gaze appears on playback.
Make the first sentence easy to follow
Video adds friction. A direct opening reduces the listener's work: answer first, then explain.
Use the lens deliberately
Looking near the camera can create the appearance of eye contact, while looking at the screen helps you read reactions. You do not have to choose one permanently. Shift deliberately at important moments.
Protect conversational presence
Pause after the question, signal when you have finished, and leave room for delay. These small adjustments reduce accidental interruption and make the exchange feel less mechanical.
The bottom line
Candidates in this experiment received lower live ratings by video than face to face. Eye contact, impression management, and social presence contributed to the difference.
The format can matter. It is not destiny, and the study does not show that qualifications stopped mattering.
Put this into practice
Use AI interview practice to make your verbal answers direct and structured. Then record a second pass on camera so you can practise the visual and conversational constraints of video separately.
