Just completed a not-IATF re-certification audit and I second doing a dry run with the auditor to ensure that any technical snafus are addressed ahead of the audit. We had issues with incompatible file formats and Web conference volume that made things awfully inconvenient. If there's a facility tour via Zoom or Facetime or whatever, then also a floor plan with clear, simple, and logically-labeled waypoints provided to the auditor so that it is clear to everyone where in the facility you are at any given point (e.g., "Waypoint A" vs. "Flux Transmogrifyer 5000 number 5" - it's easier to quickly find on floor plan). On the whole though, it went pretty well and wasn't too different from the in-person audit.
