When hiring new talent, a well-structured reference check can be the final, decisive signal that confirms your hiring decision—or reveals a critical gap that interviews failed to surface. Yet, many HR professionals default to generic questions that produce unrevealing answers: "Yes, they were a hard worker." With the right reference check questions template, you can conduct calls that consistently surface specific, actionable information about a candidate’s true performance, work style, and professional impact.

Legal Prerequisite

Always obtain written consent from the candidate before contacting any reference. In the US, most employers limit reference responses to confirming dates of employment and job title to reduce defamation risk. Your goal is to ask questions that make it easy for the reference to share positive specifics, while reading carefully for hesitation, vagueness, or conspicuous omissions.

How to Conduct Reference Checks Effectively

Before reviewing the questions, understand the structural best practices that make reference calls productive:

  • Call, don’t email: Written references are universally positive and provide no signal. Phone calls allow you to hear tone, pace, and enthusiasm—and to follow up on hesitation with probing questions.
  • Set context up front: Tell the reference the role, the responsibilities, and what you are specifically trying to validate. This focuses their answers and signals what matters.
  • Ask for specific examples, not opinions: "Would you say they were a good communicator?" produces a yes. "Can you describe a situation where their communication made a measurable difference to a project outcome?" produces evidence.
  • Listen for what isn’t said: Long pauses before "yes" answers, unusually short answers, and pivots to unrelated positives are all signals worth probing.
  • Aim for 20–25 minutes per reference: Anything shorter limits depth; anything longer exhausts the reference’s goodwill.

1. Professional Achievements and Performance (Questions 1–5)

These questions establish the candidate’s track record of delivering results and taking initiative.

  • "What were the candidate’s two or three most significant accomplishments during their time working with you?" — Look for specificity and scale. Generic praise suggests the reference doesn’t have strong recall.
  • "Did they consistently meet or exceed their performance goals or KPIs?" — Ask for examples if the answer is positive; probe what fell short if the answer is mixed.
  • "Can you describe a specific challenge they faced and how they handled it?" — Reveals problem-solving approach and resilience under pressure.
  • "Did they take initiative on projects or responsibilities beyond their defined role?" — Identifies self-starters vs. those who require direction.
  • "How would you rate their overall performance compared to others you’ve managed at the same level, on a scale of 1–10?" — The number matters less than the explanation. Anything below 7 warrants a follow-up probe.

2. Work Ethic, Reliability, and Attitude (Questions 6–10)

These questions assess the behaviors that define a candidate’s day-to-day reliability and professional attitude.

  • "How would you describe their work ethic and reliability? Could you give me an example?" — Look for concrete evidence of dependability, not a generic "very hardworking."
  • "Did they meet deadlines consistently? What happened when they faced competing priorities?" — Reveals time management and prioritization habits.
  • "How did they respond to feedback and criticism from you or other leaders?" — One of the most revealing questions. Look for evidence of growth mindset and psychological safety.
  • "Were there any patterns of behavior—positive or negative—that stood out over time?" — Open-ended and invites candor. References often use this to raise concerns they wouldn’t volunteer otherwise.
  • "What was their attendance and punctuality like?" — Simple but useful, especially for roles where reliability is operationally critical.

3. Leadership and Collaboration (Questions 11–15)

These questions assess how the candidate works with others and whether they elevate the people around them.

  • "How did they work within a team? Can you give an example of a successful collaboration?" — Assesses whether they are a team enabler or a solo contributor.
  • "Did they ever lead people—formally or informally? How did the team respond to their leadership?" — Particularly important for roles with management scope or potential.
  • "How did they handle disagreements or conflict with colleagues or stakeholders?" — Conflict management style is hard to assess in interviews; references often have direct observations.
  • "Did they contribute to a positive team culture or work environment? How?" — Identifies culture carriers vs. those who are neutral or draining on team morale.
  • "How did they handle high-pressure situations or periods of uncertainty?" — Reveals stress management and emotional regulation under pressure.

Reading Between the Lines

In the US, many employers have legal counsel advising them to only confirm employment dates and titles. If a reference gives you unusually brief or formulaic answers across multiple questions, this itself may be a signal. Ask directly: "Is there anything about this candidate’s performance or work style that would be important for me to know as a future employer?" The response—or lack of one—is informative.

4. Technical Skills and Role Suitability (Questions 16–18)

Customize these questions with the specific skills and competencies your role requires.

  • "How proficient were they in [specific skill, tool, or domain your role requires]? Can you give an example?" — Always name the specific skill. "Were they technically strong?" is too vague to be useful.
  • "How did they adapt to new tools, processes, or organizational changes?" — Critical signal for roles in fast-changing environments or organizations undergoing transformation.
  • "Do you feel their experience and skills would translate well to [brief description of your role]?" — Give enough context about the role so the reference can make a meaningful comparison.

5. The Two Most Important Questions (Questions 19–20)

These two questions—asked at the end when the reference has fully engaged—often yield the most candid and valuable responses.

  • "Would you rehire this person if you had the opportunity?" — This single question has the highest predictive validity of any reference question. A qualified "yes, but…" or a hesitation reveals more than three minutes of earlier conversation. Follow up with: "What would be the conditions or context where you’d rehire them?"
  • "Is there anything else you’d want me to know about this candidate—either as a strength or as something to be aware of—that we haven’t covered?" — Open-ended and explicit permission to share anything. Many references wait for this invitation to volunteer their most important observations.

Log Reference Check Notes in Treegarden

After each reference call, log structured notes against the candidate profile in Treegarden. Capture specific quotes, flag any concerns, and share the summary with the hiring manager before the final decision is made. Having documented reference notes creates a transparent, consistent decision-making record and protects against post-hire disputes about due diligence.

Red Flags to Watch For

Beyond the answers themselves, the following patterns in a reference call warrant careful consideration before extending an offer:

  • The reference cannot recall specific examples for any question—suggests limited direct exposure or deliberate vagueness.
  • The reference explicitly declines to answer whether they would rehire the candidate.
  • Consistently short, careful, lawyer-like answers that add nothing beyond employment confirmation.
  • Strong praise for technical skills paired with conspicuous silence on interpersonal or leadership questions.
  • A candidate who cannot provide references from direct managers—only peers or skip-level managers—for recent roles.

Using a structured reference check questions template with these 20 questions and the guidance above ensures your reference calls consistently surface real, actionable intelligence. The investment in a 25-minute call is small relative to the cost of a mis-hire—which research estimates at 30–200% of annual salary depending on seniority. With notes logged in Treegarden, your entire hiring team has visibility into what the references revealed before making the final decision.

Customize for Each Role

Build role-specific reference check templates in Treegarden for your most common hire types—manager, IC, technical, sales—and save them for reuse. Consistent templates across hiring managers ensure every reference call covers the competencies that matter most for each role type.
