15 Reference Check Questions for Recruiters to Verify Top Talent

Reference checks are one of the most valuable—and most underused—tools in a recruiter’s process. A well-conducted reference check does more than confirm employment dates and job titles. It validates a candidate’s claims, reveals how they actually perform in a working environment, surfaces strengths and growth areas that interviews alone cannot uncover, and helps recruiters make confident, informed hiring decisions.

Yet many recruiters treat reference checks as a formality: a quick call, a few generic yes-or-no questions, and a checkbox ticked. The result is a missed opportunity to gather the kind of nuanced, behavioral insight that separates a good hire from a great one—and that prevents costly hiring mistakes.

This guide provides 15 strategic reference check questions designed to give recruiters a complete, honest picture of a candidate’s performance, character, and potential. It also covers best practices for conducting reference checks in a way that is consistent, fair, and supportive of diversity hiring best practices—ensuring that your verification process strengthens rather than undermines your commitment to equitable, skills-based hiring.

Why Reference Checks Matter More Than Ever

In 2026’s hiring environment, reference checks serve several critical functions:

• Verification in the age of AI resumes: AI-generated resumes and cover letters have made it harder to distinguish genuine qualifications from polished fictions. Reference checks provide a human-verified layer of validation that no algorithm can replicate.
• Insight into soft skills: Employers increasingly value collaboration, adaptability, communication, and problem-solving—skills that are difficult to assess in a 45-minute interview but readily apparent to someone who worked alongside the candidate for years.
• Red flag detection: Patterns of behavior—missed deadlines, interpersonal conflicts, inconsistent performance—often only emerge through conversations with people who observed the candidate over an extended period.
• Reducing bad hires: A single bad hire can cost $17,000 to $240,000 depending on the role. Reference checks are a low-cost, high-impact safeguard that significantly reduce this risk.
• Supporting fair hiring: When conducted consistently using standardized, job-related questions, reference checks support equitable evaluation and reduce the influence of unconscious bias in hiring decisions—a core component of effective DEI hiring practices.

15 Reference Check Questions Every Recruiter Should Ask

Verification and Context (Questions 1–3)

Start every reference check by establishing the relationship and verifying basic facts. This sets the tone and gives you context for interpreting everything that follows.

1. “What was your working relationship with [candidate], and how long did you work together?”

This question establishes the reference’s perspective—whether they were a direct manager, peer, or cross-functional collaborator—and how well-positioned they are to evaluate the candidate. A direct manager who worked with the candidate for two years will provide different (and generally more reliable) insight than a colleague who overlapped for three months.

2. “Can you describe [candidate]’s primary responsibilities in their role?”

This verifies the accuracy of what the candidate told you during interviews and on their resume. You are listening for consistency—not word-for-word alignment, but a matching picture of scope, seniority, and impact. Significant discrepancies between the candidate’s description and the reference’s are a red flag worth exploring.

3. “What was one of [candidate]’s biggest accomplishments while you worked together?”

This is an early signal question. A reference who can immediately cite a specific, impactful accomplishment is giving you a strong positive signal. Vague or hesitant responses (“They were generally good”) may indicate a candidate who did not leave a strong impression.

Performance and Work Quality (Questions 4–7)

These questions dig into how the candidate actually performed day-to-day—not just what they achieved, but how they achieved it.

4. “How would you describe the quality and consistency of [candidate]’s work?”

This open-ended question invites the reference to characterize the candidate’s overall work quality. Listen for specific descriptors: reliable, thorough, detail-oriented, deadline-driven. Also listen for qualifiers like “usually” or “when motivated”—these often signal inconsistency.

5. “Can you describe a situation where [candidate] had to manage competing priorities or work under pressure? How did they handle it?”

This behavioral question reveals how the candidate performs when things get difficult—which is when performance differences become most visible. You are looking for evidence of composure, problem-solving, communication under stress, and the ability to deliver when it matters most.

6. “What would you say are [candidate]’s greatest professional strengths?”

Let the reference articulate strengths in their own words. Compare their answer to what the candidate highlighted in interviews. Strong alignment between the candidate’s self-assessment and the reference’s perspective is a positive indicator of self-awareness.

7. “What areas would [candidate] need to develop or improve?”

This is the growth area question, and how the reference answers it is as important as what they say. A thoughtful, specific answer (“They could improve at delegating—they tended to take on too much themselves”) is far more useful than “I can’t think of anything.” If a reference truly cannot identify a single area for development, the feedback may not be fully candid.

Collaboration and Communication (Questions 8–10)

These questions assess the interpersonal skills that determine whether a candidate will thrive on your team. They are also important for diversity recruiting best practices—understanding how a candidate works with diverse colleagues, handles differing perspectives, and contributes to an inclusive team environment.

8. “How would you describe [candidate]’s communication style? Were they effective at communicating with people across different levels and functions?”

This evaluates whether the candidate can communicate clearly with executives, peers, direct reports, and cross-functional partners. The ability to adapt communication to different audiences is a critical skill in nearly every role.

9. “How did [candidate] handle disagreements or conflicts with colleagues?”

Conflict resolution ability is one of the hardest skills to assess in interviews and one of the most important in practice. Listen for evidence that the candidate addressed issues directly, respectfully, and constructively—rather than avoiding conflict or escalating unnecessarily.

10. “Did [candidate] contribute to a positive, inclusive team environment? Can you give an example?”

This question directly addresses how the candidate interacts in a team setting and whether they contribute to an environment where diverse perspectives are valued. It is a question that aligns with DEI hiring practices by helping recruiters evaluate not just whether a candidate can do the job, but whether they will strengthen the team’s culture of respect and inclusion.

Growth, Motivation, and Potential (Questions 11–13)

11. “How did [candidate] respond to feedback? Can you share an example of how they applied feedback to improve?”

Coachability is one of the strongest predictors of long-term success. A candidate who receives feedback well and acts on it will continue to grow. A candidate who becomes defensive or dismissive of feedback is a retention and performance risk.

12. “How did [candidate] grow or develop during the time you worked together?”

This question reveals learning agility and professional trajectory. A strong answer describes specific skills developed, responsibilities expanded, or challenges overcome. It helps you assess whether the candidate has an upward trajectory or has plateaued.

13. “On a scale of 1 to 10, how would you rate [candidate]’s overall performance? And what would it have taken for them to be a 10?”

This two-part question is exceptionally effective. The numerical rating forces the reference to commit to an overall assessment (anything below an 8 is worth probing—references tend to be generous). The follow-up about what it would take to reach a 10 reveals specific development areas in a non-threatening way.

The Deciding Questions (Questions 14–15)

14. “If you had the opportunity, would you hire or work with [candidate] again?”

This is the most important single question in a reference check. Hesitation, qualifications, or a flat “no” are significant signals. A strong, immediate “Absolutely” is the best endorsement a candidate can receive. If the reference qualifies their answer (“Yes, but in a different type of role”), dig deeper to understand the context.

15. “Is there anything else you think would be important for us to know as we consider [candidate] for this role?”

This open-ended closing question gives the reference space to share anything you did not ask about. It often surfaces the most candid and valuable information of the entire conversation—references sometimes save their most honest observations for the end, when the structured questions are behind them.

Reference Check Best Practices for Recruiters

The questions you ask are only as effective as the process you build around them. Here are the best practices that ensure your reference checks are thorough, fair, and compliant:

Use Standardized Questions for Every Candidate

Ask the same core set of reference check questions for every candidate applying to the same role. Consistency is essential for fair comparison and is a foundational element of best practices for diversity hiring. Standardized questions reduce the risk of unconscious bias influencing which questions get asked of which candidates.

Stick to Job-Related Questions Only

Never ask about a candidate’s age, marital status, religion, race, sexual orientation, disability, or any other protected characteristic. Focus exclusively on the candidate’s ability to perform the job, their work behaviors, and their professional character. This is both a legal requirement and a core principle of equitable hiring.

Get Consent Before Contacting References

Always confirm with the candidate that you have permission to contact their references. This protects the candidate’s privacy, maintains trust in your hiring process, and ensures compliance with applicable regulations.

Prioritize Direct Managers

Former direct supervisors provide the most reliable and comprehensive feedback. Peer references and client references are useful supplements, but the manager’s perspective on performance, growth, and reliability carries the most weight. Request two to three references, prioritizing people who managed the candidate directly.

Listen for Patterns, Not Isolated Comments

A single negative comment does not necessarily disqualify a candidate. Look for patterns across multiple references. If two or three references independently mention the same development area or concern, it is likely a genuine pattern worth factoring into your decision.

Document Everything

Take structured notes during every reference call and store them alongside the candidate’s file in your ATS or recruiting platform. This creates a defensible record of your process and ensures that reference insights are shared with hiring managers and accessible for future reference.

How Reference Checks Support Diversity Hiring Best Practices

When done well, reference checks are an important tool in diversity sourcing best practices and equitable hiring. Here is how:

• Consistency reduces bias: Using the same questions and evaluation criteria for every candidate ensures that all individuals are assessed on the same terms, regardless of background. This is one of the simplest and most effective DEI hiring practices available.
• Skills-based evaluation: Reference check questions focused on behaviors, accomplishments, and competencies evaluate candidates on what they can do—not on where they went to school, who they know, or how polished their interview presence is.
• Reduced reliance on gut instinct: Adding third-party validation to the hiring process counterbalances the subjective impressions that can be influenced by affinity bias, halo effects, and other unconscious patterns.
• Inclusive team assessment: Questions like #10 (“Did the candidate contribute to a positive, inclusive team environment?”) directly evaluate whether a candidate will support and strengthen a diverse team.

Of course, equitable hiring starts long before the reference check. Building diverse candidate pipelines requires proactive, multi-channel sourcing that reaches qualified candidates from all backgrounds—not just those who happen to apply through a single job board. AI-powered recruiting platforms like GoPerfect help recruiters build broader, more diverse pipelines by automating candidate sourcing across large talent databases and using AI matching that evaluates skills and qualifications objectively—reducing the sourcing-stage bias that can narrow the pipeline before reference checks even begin.

Common Reference Check Mistakes to Avoid

• Asking only yes/no questions: Binary questions (“Was the candidate good at their job?”) generate surface-level responses. Use open-ended and behavioral questions that invite specific examples and nuanced feedback.
• Skipping reference checks for “obvious” hires: Even candidates who perform brilliantly in interviews can have patterns that only emerge through reference conversations. Never skip this step, regardless of how confident you are.
• Relying only on candidate-provided references: Candidates naturally choose references who will speak positively about them. Where appropriate and with consent, seek additional perspectives such as former managers from earlier roles.
• Conducting references after the decision is already made: If you treat reference checks as a formality after you have already mentally committed to a candidate, you are unlikely to weigh the information objectively. Conduct references before making your final decision.
• Inconsistent process across candidates: Varying your approach—asking more questions for some candidates, skipping references for others—introduces bias and creates legal risk. Standardize your process and apply it uniformly.

Frequently Asked Questions

What are reference check questions?

Reference check questions are the questions a recruiter or hiring manager asks a candidate’s former employers, managers, or colleagues to verify the candidate’s qualifications, assess their past performance, and gather insight into their work style, strengths, and areas for development. Effective reference check questions are open-ended, behavioral, job-related, and standardized across all candidates for the same role.

When should recruiters conduct reference checks?

Reference checks are typically conducted after the interview stage and before the final hiring decision. Some recruiters run them in parallel with the offer stage to save time, but the information should be reviewed and factored into the decision before the offer is finalized.

How many references should I check?

Two to three references is the standard range. Prioritize former direct managers, as they can provide the most complete and reliable assessment. One reference may not give you enough perspective, while more than three typically produces diminishing returns.

How do reference checks support diversity hiring best practices?

Standardized, job-related reference checks support diversity hiring best practices by ensuring every candidate is evaluated on the same criteria. Consistent processes reduce unconscious bias, skills-based questions focus evaluation on competencies rather than background, and inclusive team culture questions help assess whether a candidate will contribute to a respectful, diverse work environment.
