Service Technicians interview scorecard

Evaluate Service Technicians candidates across 4 weighted areas: hands-on competence, safety discipline, fault finding, and reliability and conduct. Hands-on competence leads at 35%, so check which equipment lines they service unsupervised: pumps, compressors, HVAC units, CNC drives or forklifts, plus hands-on work with multimeters, torque wrenches, alignment tools and OEM service manuals. Use the rubric to compare role-specific evidence consistently.

TL;DR
For hands-on competence, look for evidence the candidate names specific makes and models serviced, describes overhaul and calibration steps in sequence, and cites first-time-fix rates or callback numbers. For safety discipline, look for evidence the candidate treats LOTO and permit steps as non-negotiable, recalls a job they stopped, and holds current certifications with documented refresher training. Apply the written 1–5 anchors to every answer, record the evidence behind each rating, and use the factor weights to reach a consistent overall assessment.

What to assess and how to score it

Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.

01
Evaluation factor

Hands-on competence

35% weight

Check which equipment lines they service unsupervised: pumps, compressors, HVAC units, CNC drives or forklifts, plus hands-on work with multimeters, torque wrenches, alignment tools and OEM service manuals.

Evidence to listen for

  • Names the equipment, materials, and tolerances they work to
  • Can describe a job start to finish without hand-waving the hard parts
  • Holds the tickets, licences, or certifications the work requires, and they are current
  • Knows what they are not qualified to touch

Five-point scoring guide

1
Poor

Cannot describe the work concretely; lacks required tickets or licences.

2
Needs Improvement

Basic familiarity; needs supervision on routine tasks.

3
Satisfactory

Competent on standard work; slower or unsure on unfamiliar jobs.

4
Very Good

Skilled and independent across the normal range of the role.

5
Excellent

Names specific makes and models serviced, describes overhaul and calibration steps in sequence, and cites first-time-fix rates or callback numbers.

02
Evaluation factor

Safety discipline

30% weight

Probe lockout/tagout practice, PPE discipline, arc flash or confined space training, refrigerant handling (EPA 608) and how they handle a customer pushing them to skip a step.

Evidence to listen for

  • Treats procedure as protection rather than paperwork
  • Can describe a time they stopped work and why
  • Knows the specific hazards of this trade and the controls for each
  • Reports near misses instead of hiding them

Five-point scoring guide

1
Poor

Casual about safety; describes shortcuts with pride.

2
Needs Improvement

Follows procedure when watched; cannot name the hazards that matter.

3
Satisfactory

Sound safety habits; less certain on unfamiliar hazards.

4
Very Good

Safety is instinctive; can describe stopping work over a real concern.

5
Excellent

Treats LOTO and permit steps as non-negotiable, recalls a job they stopped, and holds current certifications with documented refresher training.

03
Evaluation factor

Fault finding

20% weight

Test diagnostic method on intermittent faults: reading error codes, tracing hydraulic or electrical schematics, vibration or thermal readings, and deciding repair versus replace on aging assets.

Evidence to listen for

  • Has a method for narrowing a fault rather than swapping parts
  • Reads schematics, manuals, or error codes and acts on them
  • Knows when to escalate rather than guess
  • Can describe a fault that took real work to find

Five-point scoring guide

1
Poor

Parts-swapper; no diagnostic method.

2
Needs Improvement

Fixes symptoms; cannot explain how they found the cause.

3
Satisfactory

Solid on familiar faults; less structured on new ones.

4
Very Good

Clear systematic method with a real hard-fault story.

5
Excellent

Walks a fault from symptom to root cause with instrument readings, and explains what they ruled out before swapping any part.

04
Evaluation factor

Reliability and conduct

15% weight

Assess service record habits: work order completion in the CMMS or field app, parts van inventory, response times on emergency calls, and conduct on customer sites.

Evidence to listen for

  • Turns up, on time, prepared
  • Handles shift work, callouts, or travel as the role requires
  • Documents work so the next person can pick it up
  • Deals with customers or site staff professionally

Five-point scoring guide

1
Poor
