Vetting and the paid trial

Interviews are performances and everyone knows their lines. The candidate who charms you at the kitchen table can be a different person at seven in the morning on a job that went sideways. The craft of vetting is stacking weak predictors until they are strong: structured questions, references, and above all, watching the work happen.

The structured interview

Same questions, every candidate, written down before the first one walks in. Unstructured conversations feel revealing and predict almost nothing, because you end up hiring the person you enjoyed talking to.

Half your questions are scenarios drawn from the actual job, and you already own them, because the job just happened to you last month. "A client says at the walkthrough that the job isn't right. Walk me through exactly what you do." "Two jobs are booked back to back and the first runs long. What happens next?" "You're alone on a job and something breaks, something of the client's. What do you do in the next ten minutes?" There are no correct answers on a card; you are listening for ownership, sequence, and whether their instinct protects the client relationship or themselves.

The other half are evidence questions, the kind a cleaning operator's interview script in my research nailed: not "are you detailed" but "how long does a standard clean of a two-bedroom take you, and what do you do in the last fifteen minutes." Not "are you reliable" but "tell me about the last job you left, and the one before that." Dates and numbers are hard to fake smoothly; adjectives are easy.

Also say the hard parts out loud one more time, in person, and watch the face. The physical reality, the schedule, the pay, the standard. Consent to the real job, not the imagined one.

References: before the offer, not after

Call two past supervisors or clients before any offer, not as a formality after you have already decided emotionally. One question matters more than all the others: would you hire this person again? Everything else can be dressed up; that pause before the answer cannot.

Ask one more: what job were they best at, and what job were they wrong for? You are not just validating the person; you are checking that the job you have is the job they are good at. A great worker mismatched to your role is a mis-hire with great references.

The paid trial

Here is the strongest predictor available to a small business: one to two weeks of real work, real conditions, real pay, defined scope, and a decision date named on day one.

The trial is not a formality and it is not cheap labor. It is the working interview that operators across the trades converge on, for a blunt reason found in thread after thread: the hardest part of the job is showing up. Operators describe candidates who interviewed beautifully, accepted the job with visible joy, and then simply never appeared on the first morning. The trial deletes that entire class of surprise before you have ordered a payroll account, told your customers, or rearranged your routes.

Run it like this.

Real work, not invented tasks. The trial does the actual job on the actual schedule. If the job is Thursday and Friday routes, the trial is Thursday and Friday routes.

Watch three things. Pace: are they within a reasonable distance of the standard by day three, improving, not perfect? Questions: do they ask good ones early, or go silent and guess? Care at the end: the last hour of a shift, the last corner of the job site, the end of the edit, is where character shows. Skills can be trained. Care at the end has to arrive with the person.

Correct them once, deliberately, on something small, early. You are not testing whether they make no mistakes. You are testing what happens after a correction: defensiveness, invisibility, or adjustment. You will be correcting this person for years; find out now what it costs.

Name the decision date before the trial starts. "This is two weeks. On Friday the fifteenth I'll tell you yes or no, either way, directly." Then keep that promise on the day. A trial with no named ending is just a job with lower pay and higher stress.

Background checks where the work demands them, entering homes, driving, caring for people, handling money, are their own subject and the trade courses cover what their lane requires. For the decision itself, the trial and the reference calls are your evidence.

And hold the discipline at the finish. The candidate who was fine. The one you feel a little sorry for. The one your spouse liked. If the evidence says no, the answer is no, today, kindly, in a sentence. Slow yes, fast no, is the whole temperament of good hiring. What a real yes costs you in money and paperwork, and what to do in the first week after you say it, is next.
