Step 3 · Interview How to interview for each commercial flooring role.
Everyone who applies will claim the experience. These are the questions that test it, the signals that separate a strong candidate from a plausible one, and the mistake each seat invites.
Commercial Carpet Installer
My Trade Talent band Installs commercial broadloom and carpet tile: subfloor preparation and moisture testing, layout and seam planning, direct glue-down and double-stick, pattern match, and transitions to other surfaces. Most commercial carpet failures start under the carpet.
Questions that find out
- How do you test a slab for moisture and what reading stops the installation?
- How do you lay out seams in a corridor with windows down one side?
- What goes wrong with quarter-turn carpet tile installation and how do you avoid it?
What a strong candidate shows
- Tests and documents subfloor moisture rather than assuming the slab is ready
- Plans seams against the light and the traffic pattern, not just the roll width
- Has installed carpet tile in occupied space in phases
The mistake this seat invites. Hiring on square footage installed and skipping the subfloor questions. The moisture test is the part that decides whether the job comes back.
LVT / Hard Surface Installer
My Trade Talent band Installs luxury vinyl tile and plank, sheet vinyl, rubber and other resilient hard surfaces: substrate preparation and levelling, moisture mitigation, adhesive selection, layout, welding on sheet goods, and base and transition work.
Questions that find out
- The slab is out of flat by a quarter inch over ten feet. What do you do before you install?
- How do you choose between a pressure-sensitive and a hard-set adhesive?
- Walk me through heat-welding a sheet vinyl seam in a patient room.
What a strong candidate shows
- Treats substrate flatness as the controlling variable, because LVT telegraphs everything under it
- Knows which adhesive goes with which product and moisture condition
- Has heat-welded sheet vinyl seams in healthcare or similar environments
The mistake this seat invites. Assuming carpet installers convert directly. Resilient work is less forgiving of the substrate and the adhesive choice, and the failures are visible.
Polished Concrete Installer
My Trade Talent band Grinds, densifies and polishes concrete slabs to a specified finish: progressive diamond grit sequence, densifier application and cure, aggregate exposure class, joint filling, and the gloss or clarity level the specification names. The slab that exists sets the ceiling on the result.
Questions that find out
- The owner wants Class C aggregate exposure on a slab that was finished hard. What do you tell them?
- Walk me through your grit sequence to an 800 finish.
- When do you apply densifier and what goes wrong if you apply it too early?
What a strong candidate shows
- Speaks in grit sequence and exposure class rather than "polished"
- Assesses the slab before committing to a finish level
- Understands densifier timing and what happens when it is rushed
The mistake this seat invites. Selling or hiring against a photograph. The finish achievable depends on the existing slab, and the expectation conversation is part of the skill.
Commercial Flooring PM
My Trade Talent band Manages commercial flooring projects: takeoff and buyout, material lead times and dye lots, moisture testing and mitigation decisions, phasing in occupied buildings, installer scheduling across jobs, and the attic stock and closeout the owner expects.
Questions that find out
- Moisture testing comes back high two days before installation. What happens?
- How do you phase a floor replacement in an occupied office?
- A dye lot shortage leaves you short on a corridor. What are your options?
What a strong candidate shows
- Manages dye lot and lead time as a scheduling constraint from the start
- Has made the moisture mitigation call and can explain who paid for it
- Phases occupied-building work around the tenant, not around the crew
The mistake this seat invites. Treating flooring as a commodity buy. The moisture decision and the phasing plan are where the margin and the disputes live.
Every role in every trade is in the interview question bank.
