Technology at home
Check your setup before an important video call
Technical trouble is harder to handle on an important call. Checking audio, video, connection, and background ahead of time catches most problems while there is still room to fix them.
What to check in the answer
Zoom's audio and video tests live in its settings, so the checklist should use those and not an outside website. Check that it covers every item you asked for: microphone, camera, background, lighting, closing unneeded apps, and your display name. Lighting advice should be easy to verify, such as facing a window instead of sitting with one behind you. If the checklist mentions a feature you do not recognize, look it up in Zoom's help pages before relying on it.
What to do next
Run the full check the evening before as well as the morning of. A hardware problem found early leaves time to borrow a microphone or switch to a wired connection. Save the meeting link and your interviewer's contact details somewhere other than a browser tab you might close by accident.
