You can teach the skill. You cannot teach the character.

Every owner who has hired badly says a version of the same sentence afterwards: "he could run the machine, but..." The machine was never the problem.

Skill is the part you can fix — a competent hand learns your way of doing a thing in a few weeks, and you have been teaching people on jobsites your whole working life.

What you cannot fix is whether he tells you about the gouge in the driveway or hopes you do not notice.

So the interview is not an exam on the trade. You can measure the trade in an afternoon, which is what the trial day is for. The interview is for the part that takes a year to find out the hard way.

In a trades business, four things carry almost all of it. Does he show up, on the day, at the time, without a story? Does he tell the truth when the news is bad and it is his fault?

Does he treat the customer's property like it belongs to someone he respects? And does he do the last ten percent of a job — the broom, the gate latched, the cutoffs out of the flower bed — when nobody is watching and he could leave?

A worked example of the difference. Two hands both tell you they ran a skid steer for three years. The first one, asked about a time he damaged something, says he never has.

The second says he clipped a downspout backing out of a tight side yard, told the homeowner before he told his boss, and it came out of the job's margin instead of becoming a dispute.

The second answer is worth more than the three years. The first is a man who either has not worked enough to break anything, or will not tell you when he does.

None of this is about being a nice person. Plenty of good hands are blunt, quiet, or hard work to manage.

Character here means specific, observable, boring reliability — the things that decide whether sending him alone to a customer's house costs you a callback or wins you a referral.

WORKSHEET 1. Write down the last three times a job went wrong because of a person rather than a price. Name what the person actually did, or failed to do. 2. Turn each one into a question about a stranger's own past — "tell me about a time", never "what would you do if". 3. Keep those questions. They came out of your own scar tissue, which is why they will beat any list you download.
