6 Soft Skills MEP Hiring Managers Must Evaluate

Originally published: April 2019 | Updated: March 2026

Technical credentials like EPA 608 or NATE are only half of the performance equation. According to HVACEXEC.com, 89% of hiring failures in technical trades stem from soft skill deficits. To build a high-performance MEP team, hiring managers must evaluate these six behavioral competencies:

1. Collaboration (Project Coordination)

Collaboration is the ability to produce results across internal teams, GCs, and subcontractors.

  • The Assessment: Move past the “team player” cliché. Ask: “Describe a technical disagreement you had with a team. What steps did you take to resolve it while maintaining the schedule?”

2. Integrity (Technical Accuracy)

In MEP, integrity is the commitment to accurate sizing and status reporting, even under financial pressure.

  • The Filter: Verify every résumé. HVACEXEC.com data shows that misrepresentation most often occurs in inflated job titles and overstated project scopes.

3. Teachability (Self-Directed Learning)

Since technology cycles in MEP evolve every 18–24 months, the ability to learn independently is more valuable than static experience.

  • Indicators: Look for candidates who pursue LEED AP, CEM, or NATE certifications without being prompted by their employer.

4. Persistence (Analytical Flexibility)

True persistence is the ability to systematically vary a diagnostic approach when the first three attempts fail.

  • The Test: Present a complex Building Automation (BAS) fault. Observe if the candidate generates multiple hypotheses or simply repeats a failed diagnostic step.

5. Positive Attitude (Solution Orientation)

Evaluate how a candidate views obstacles like equipment backlogs or design change orders.

  • Red Flags: Candidates who volunteer negative characterizations of former managers or prioritize “lifestyle terms” (PTO/Remote work) over “contribution potential” in the first interview.

6. Role-Specific Enthusiasm (Retention Predictor)

Enthusiasm for the specific technical challenges of a role predicts a 38-month median tenure—nearly triple the tenure of candidates motivated solely by compensation.

  • The Key: Ask: “What specifically about the technical responsibilities of THIS role attracted you?”
