The Working Interview: Try Before You Hire

Why this matters

A resume tells you what someone wrote down. An interview tells you how they talk. Neither tells you whether they can actually do the work, show up on time, treat a customer's home with respect, or keep a clean truck. The only thing that tells you that is watching them do it. A working interview, a paid trial day or shift in the field, catches the mismatches that a conversation never will. It is the single highest-leverage screening step a small shop has.

What a working interview is (and is not)

A working interview is a short, paid stretch (a half day to a few days) where the candidate works alongside an experienced tech on real jobs. You watch, you do not lecture. They are there to show you who they are under normal conditions.

It is not free labor. Pay them for the time, at a fair rate, the same as any worker. Treating a trial as unpaid is both unfair and a legal risk in most places. Pay also signals that you take them seriously, which is exactly the relationship you want to start.

It is also not a hazing or a test of how much abuse they will take. It is a fair look at normal work.

Set it up so you learn something

A working interview only works if it is structured. Decide in advance what you are looking for.

• Pair them with your best, not your worst. Put them with a steady senior tech who models how you want the work done and can report back honestly.
• Pick a representative day. Not your easiest stop, not your hardest. A normal mix so you see normal behavior.
• Brief the senior tech on what to watch. Punctuality, attitude when a job goes sideways, how they handle the customer, whether they ask good questions or fake it, how they treat tools and the truck.
• Tell the candidate the plan. Where to meet, what to bring, how they will be paid, how long it runs. Watching them follow simple instructions starts the evaluation before the work does.

What to watch for

Skills can be taught. The things below are mostly who a person is, and they are exactly what a resume hides.

• Do they show up early, on time, or scrambling? Day one is their best behavior. Late on day one is a forecast.
• How do they treat the customer's space? Drop cloths, wiping feet, not leaving a mess. You cannot train someone into caring; you can only see whether they already do.
• What happens when something goes wrong? A part is missing, the diagnosis is harder than expected. Do they stay calm and problem-solve, or do they get frustrated and sloppy?
• Do they ask or do they bluff? A green tech who asks a smart question is gold. A tech who pretends to know and guesses is dangerous.
• Hands and habits. Clean work, safe work, organized tools. Speed matters less than care; speed comes with reps.

Run a fair, honest debrief

At the end, talk to two people separately.

First, the senior tech: get the unfiltered read while it is fresh. Ask specific questions, not "what did you think." Ask "would you want them on your truck next week."

Second, the candidate: ask how the day went for them, what they liked, what surprised them. You are checking fit both ways. A tech who hated the work will not stay even if you hire them.

Make the call, then close it cleanly

If it is a yes, make the offer promptly. Good candidates have other options and momentum matters.

If it is a no, be straight and kind. Pay them for the time, thank them, and tell them plainly it is not the right fit. Do not ghost them. The trades are a small world and word travels. A respectful no protects your reputation as much as a good hire does.

Stay inside the lines

Rules on paid trials, classification, and worker protections vary by state and locality. The safe default is simple: pay for the time worked, treat the person as a worker for that day, and do not have them perform unsupervised work or sign off on anything. When in doubt about pay or classification, confirm with your state labor office or an employment attorney.
