When a shortlist comes back wrong, the diagnosis is almost always the same from the hiring manager’s side: the recruiter did not understand the role. It is occasionally true. Far more often, the brief was thin, and the recruiter filled the gaps with reasonable assumptions that happened not to match yours.

A good brief takes about forty minutes. It is the highest-leverage forty minutes in the entire hiring process, and it is routinely replaced by a forwarded job description and a phone call.

Describe the work, not the person

Most briefs start with a person specification: five years’ experience, strong communicator, team player, attention to detail. Almost none of that is discriminating. Nobody advertises for a weak communicator.

Start instead with what the person will actually do in their first ninety days. Not the job description, which is usually a list of responsibilities written for a different purpose, but the real work.

What does a Tuesday look like? What equipment do they touch? Who do they report to and how often? What is the first task they will be given? What does the site look like at 6am in July?

A recruiter who knows the work can assess a candidate against it. A recruiter working from adjectives can only screen for keywords.

Separate the must-haves from the preferences

This is the single most useful thing you can do, and the most frequently skipped.

Write two lists. The first is the things without which a candidate cannot do the job on day one: the licence class, the ticket, the physical requirement, the right to work, the ability to be on site at a specific time. Keep this list short and be ruthless about it. Every item you add narrows the pool, and some of them narrow it dramatically.

The second list is everything else. Preferred experience, sector background, systems familiarity, qualifications you like but do not need.

Then interrogate the first list. Is five years’ experience actually a must, or is it a proxy for competence you could assess directly? Is a specific sector background required, or does it just make the induction shorter? In a market where Canterbury unemployment sits under 4 percent, every unnecessary must-have costs you real candidates.

Be specific about the non-negotiables that are not skills

The requirements that most often break placements are not technical.

Start time and location. “Christchurch” covers a lot of ground and a 6am start in Rolleston is a different proposition from an 8am start in Sydenham. Say which.

Shift pattern and expected hours, including whether overtime is occasional or routine.

Physical demands, stated plainly. Lifting, standing, working at height, working in cold or wet conditions.

Site requirements. Drug and alcohol testing, inductions, PPE, any client-specific compliance.

Duration and what happens at the end. Is this a fixed term, an ongoing role, or a temporary placement with a realistic prospect of going permanent?

Rate, including whether it is negotiable and what the range actually is. Recruiters who do not know the range cannot manage candidate expectations, and candidates who discover the rate at offer stage decline at offer stage.

Give them the honest version of the role

Every job has something about it that is hard. Long hours in the peak. A difficult client. A commute. A supervisor with a direct manner. Physical work in bad weather.

Briefs that omit this produce shortlists that look good and placements that end in week three. Tell the recruiter what the hard part is and let them screen for people who can handle it. Candidates who are told upfront and take the job anyway are the ones who stay.

The same applies to why the role is open. A vacancy created by growth, by a resignation, or by a dismissal are three different conversations, and a recruiter who knows which one it is will ask better questions.

Agree the process before it starts

Decide, in the brief, how the process will run: how many candidates you want to see, how quickly you will give feedback, who is involved in the decision, and how fast you can move to offer.

Two commitments matter more than the rest. Feedback within 48 hours of receiving a CV, and a decision-maker who is actually available in the week the shortlist lands. Most lost candidates in tight markets are lost to delay, not to a competitor’s better offer.

Agree what feedback looks like too. “Not quite right” tells a recruiter nothing. “Good technically, but he needs a 7am start and we begin at 6” recalibrates the entire search.

Setting these expectations early is also how you tell the difference between recruitment agencies christchurch businesses keep going back to and ones that simply forward applications, because the good ones will push back on a brief that does not hold together.

Treat the first shortlist as calibration

Even a strong brief will not produce a perfect first shortlist, and it does not need to. Treat it as a calibration exercise.

Go through each candidate and say specifically what was right and what was wrong. Two rounds of that will get most searches on target. Silence, or a blanket rejection with no detail, guarantees the second shortlist looks like the first.

The recruiter is working from your model of the role. The only way they get a better model is if you keep giving them one.
