Candidate screening: filtering fairly before the interviews start

Candidate screening is the stage where most hiring decisions are actually made, and the stage that gets the least thought. A pile of applications is reduced to a shortlist in an afternoon, usually by one person forming impressions quickly — and the criteria that did the reducing are rarely written anywhere, which makes the result impossible to defend and impossible to improve.

Set the criteria before reading anything

• Three or four requirements that are genuinely essential, each one something you could verify rather than sense.
• A separate list of what is desirable, kept visibly apart so it does not quietly become essential.
• The evidence that would satisfy each requirement, decided in advance — otherwise the evidence becomes whatever the strongest-sounding applicant happened to provide.
• Nothing about tenure at previous employers without a reason you could state out loud.
• Nothing you cannot ask about directly, since screening on it indirectly is the same decision with a worse paper trail.

What a candidate screening call is for

Four things, and no more: confirming the facts you need, checking the practical constraints, answering their questions, and giving them a reason to continue. It is not a short interview, and treating it as one wastes the main advantage of the stage — fifteen minutes that prevents a wasted hour on both sides. The practical constraints are the part people skip and then discover at offer stage: availability, notice period, location, the realistic salary range. Raising money early is kinder than discovering a gap after three rounds.

Screen the application against the criteria rather than against the other applications. Comparative reading produces a shortlist relative to whoever else happened to apply that week, which is why some rounds shortlist nobody good and others reject people who would have been fine.

The shortcuts that become discrimination

Most of them are not intended as filters at all. Screening out employment gaps disadvantages carers disproportionately. Requiring a degree for work that does not need one filters by background rather than ability. Discounting overseas qualifications, or names that are hard to pronounce, happens through inattention rather than intent — and that is precisely why a written set of criteria applied consistently is the protection, for the candidates and for you. If a decision cannot be explained by reference to a criterion written down beforehand, it was made on something else.

Making it consistent

1. Use the same questions in the same order for every screening call, and write the answers down during it.
2. Score against the criteria immediately rather than at the end of the day, when impressions have blurred into a ranking.
3. Have a second person review the rejections for one round a year; the pattern is more informative than any single decision.
4. Record a one-line reason for every rejection, consistently applied — inconsistency across candidates is what gets read unfavourably later.
5. Keep the notes for the period you stated, then delete them, since screening notes are personal data like everything else in the file.

Ettex Forms is a sensible front door here: the same questions asked of everybody, the answers in fields rather than in attachments, so applications can be compared against criteria instead of read as prose. The record of who reached which stage and why belongs with the applicant tracking rather than in the mailbox where it was decided.
