The rules you would want are the ones the product enforces.
Every one of these is written into the code, not into a prompt an intelligent system might ignore. The answer to legal, to the board and to a candidate who asks.
Unfair questions removed on save.Relocation, right to work, age, marriage, gender, nationality: stripped from an interview script, with the category named.
Accent, grammar and mood never scored.Reasoning and engagement are scored instead. Communication is judged on substance.
Nothing invented into the advert.A pay figure you never gave is stripped out. A title you typed never gains a word.
Low confidence over guessing.Anything the material does not evidence is reported as unclear, never flattered into a score.
Decisions are frozen.Requirements and the candidate's profile are recorded as they stood on the day. Changing them later never rewrites a decision about a real person.
Candidates read their own words too.A decline names the requirement in the words you set. Recording retention is stated before consent and kept.
