Recorded answers give a hiring panel something a phone screen never can: everyone assesses the same evidence, in the same conditions, without one person's recollection standing in for the interview.
It is remarkably easy to throw that away.
Score before you discuss
The moment someone says "I thought candidate three was great" in a shared channel, everyone else's read is contaminated. Anchoring is not a character flaw, it is how people work. The fix is procedural: everyone watches and records a score on their own, and the discussion starts only once the scores are in.
The disagreements that survive that process are the valuable ones. They usually mean two reviewers are weighting different things, which is a conversation worth having before you make an offer rather than after.
Review by question, not by candidate
Watching every answer from one person and then moving to the next builds a story about each individual. Watching how eight people answered question two builds a scale. You will calibrate faster, and you will notice when a question was badly worded because everyone struggled with it in the same way.
Write the bar down before you start
Not a rubric with weights and decimals — just a sentence per question describing what a strong answer contains. Ten minutes of work, and it converts "I liked them" into something you can defend to the next reviewer and to the candidate.
If you cannot say what a good answer would have contained, you are not screening. You are auditioning.
Stop watching when you know
This is a real advantage and people feel guilty using it. If two questions in, the answer is clearly no, you do not owe the recording the remaining six minutes. Note why and move on. The candidate is better served by a fast reply than by a thorough viewing that reaches the same conclusion a fortnight later.
