Tell the interviewer immediately that the video appears frozen while confirming that you can still hear them. Do not spend several minutes pretending the connection is normal.

If audio is stable, they may choose to continue while you reconnect video. If the platform is failing more broadly, follow their direction on whether to pause or rejoin.

Keep a backup device or phone available if the interview instructions allow it, and close unnecessary applications before the call to reduce avoidable technical issues.

Afterward, only follow up with recruiting if the disruption materially affected the interview or the interviewer asks you to. A brief technical interruption is not automatically a problem. Test camera permissions and platform settings beforehand too, since a frozen image can come from software configuration rather than the internet connection itself.

Say something right away. Sitting there frozen while pretending it's fine would be awkward.
