Reference Check Questions: 40+ Examples

Reference check questions are the specific questions you ask a candidate's former managers, colleagues, or supervisors to verify their work history, skills, and character before making a hiring decision. Done well, they separate a great hire from a costly mistake.

According to SHRM's talent acquisition research, the average cost of a bad hire ranges from 50% to 200% of that employee's annual salary. For a small team where every person carries outsized impact, one wrong hire can derail projects, tank morale, and drain your runway.

This guide gives you 40+ ready-to-use reference check questions organized by category — plus a step-by-step process and a free template you can use on your next call.

Why Reference Checks Matter (Especially for Small Teams)

A 15-person startup in Portland learned this the hard way. They hired a senior developer who interviewed brilliantly — confident, articulate, technically sharp. Three months in, they discovered he couldn't work independently, missed deadlines consistently, and created tension with the engineering team. A single call to his previous manager would have revealed a pattern of the same behavior.

Big companies can absorb a bad hire. Small teams can't. When your team is 10 people, one underperformer affects 10% of your output. When it's 50 people, you still feel the ripple across an entire department.

Reference checks do three things that interviews alone cannot:

The U.S. Equal Employment Opportunity Commission notes that reference checks — when conducted properly — are a legitimate and recommended part of the pre-employment screening process. They're not just a formality. They're a safeguard.

When to Conduct Reference Checks

Timing matters. Check references too early and you waste time on candidates you haven't vetted. Too late and you've already emotionally committed to an offer.

The sweet spot: after the final interview round but before extending a formal offer. You've narrowed your list to one or two finalists. You're 90% sure. Reference checks are that final 10%.

Here's a practical timeline within your hiring process:

1. Initial screen → Phone or video intro
2. Interviews → Skills assessment, culture interviews, scorecard evaluation
3. Reference checks → 2–3 calls per finalist (you are here)
4. Offer → Extend with confidence

Most reference calls take 10–15 minutes. Budget 2–5 business days for scheduling and follow-up, since former managers aren't always easy to reach.

General Reference Check Questions

Start every call with these foundational questions. They verify facts, build rapport with the reference, and set up deeper follow-up questions.

1. What was your working relationship with [candidate]?
2. How long did you work together, and in what capacity?
3. What were their primary responsibilities in their role?
4. How would you describe their overall performance?
5. What are their greatest professional strengths?
6. Can you describe an area where they could improve?
7. Why did they leave your organization?
8. Would you rehire them? Why or why not?
9. How did they handle feedback — both giving and receiving it?
10. Is there anything else you think I should know about working with them?

The "Would you rehire?" question is particularly telling. A confident "Absolutely" is a green light. A pause followed by qualifiers ("Well, it depends on the role...") tells you everything you need to know.

Pro tip: Ask the candidate to give their references a heads-up that you'll be calling. References are significantly more candid when they're expecting the call and feel they're helping their former colleague.

Performance-Focused Reference Check Questions

These questions dig into how the candidate actually delivered results — not just whether they showed up.

11. Can you describe a major project or accomplishment they led?
12. How did their performance compare to others in a similar role?
13. Did they consistently meet deadlines? Can you give an example?
14. How did they handle a situation where they missed a target or fell short?
15. On a scale of 1 to 10, how would you rate their [specific skill relevant to your role]?
16. Were they more effective working independently or as part of a team?
17. How did they prioritize when managing multiple competing deadlines?
18. Did they take initiative beyond their defined responsibilities?

When asking about specific skills, tailor question 15 to your actual needs. If you're hiring a marketing manager, ask about campaign management. If it's a support role, ask about customer communication. Generic questions get generic answers.

A useful follow-up after any rating question: "Can you give me a specific example?" Numbers without context are meaningless.

Culture Fit Reference Check Questions

Skills get people hired. Culture misalignment gets them fired. These questions help you understand how someone operates within a team dynamic.

19. How would you describe their communication style?
20. How did they handle disagreements or conflict with colleagues?
21. What type of work environment did they thrive in most?
22. How did they respond to changes in priorities or company direction?
23. Did they contribute to team culture? In what way?
24. How would their closest colleagues describe them in three words?

A Harvard Business Review study found that unstructured impressions during interviews are poor predictors of job performance. Culture fit questions during reference checks provide a more reliable signal because you're hearing from someone who worked alongside the candidate for months or years — not someone who met them for an hour.

Question 24 is especially powerful. It forces the reference to think beyond their own relationship and consider the candidate's broader reputation.

Management and Leadership Questions

Use these when hiring for roles that involve leading others — managers, team leads, department heads.

25. How many people did they manage directly?
26. How would their direct reports describe their management style?
27. Can you share an example of how they developed or mentored a team member?
28. How did they handle underperformance on their team?
29. Were they effective at delegating, or did they tend to micromanage?
30. How did they communicate team goals and priorities?

For small teams, leadership doesn't always mean a formal "manager" title. You might be hiring your first team lead or a senior IC who'll mentor junior hires. Adjust these questions to fit the actual scope of the role.

One question that reveals management maturity: "How did they handle underperformance?" Great managers address it directly with coaching and clear expectations. Weak managers either ignore it or escalate too harshly. The answer tells you which type you're getting.

Questions to Avoid (Legal Risks)

Not all reference check questions are legal. Asking the wrong ones can expose your company to discrimination claims under federal and state employment law.

Never ask about:

Stick to job-related questions about performance, skills, and work habits. If a reference volunteers personal information, don't record it or factor it into your decision.

When in doubt, ask yourself: "Does this question directly relate to the candidate's ability to do this job?" If not, skip it.

Reference Check Template

Copy this template and use it on your next reference call. It covers all the essential categories in a 10–15 minute conversation.

Before the call:

• Confirm the reference's name, title, and relationship to the candidate
• Review the candidate's resume and interview notes
• Prepare 8–10 questions tailored to the role

Opening (1 minute):

• Introduce yourself and your company
• Confirm it's a good time to talk
• Assure them the conversation is confidential

Verification questions (2 minutes):

• What was your working relationship?
• What were their dates of employment and role?
• What were their main responsibilities?

Performance questions (4 minutes):

• How would you rate their overall performance?
• Can you describe a major accomplishment?
• How did they handle setbacks or missed targets?

Culture and teamwork (3 minutes):

• How did they work with colleagues?
• What type of environment did they thrive in?
• How did they handle feedback?

Closing (2 minutes):

• Would you rehire this person?
• Is there anything else I should know?
• Thank them for their time

After the call:

• Document responses immediately (don't rely on memory)
• Compare notes across multiple references
• Flag any inconsistencies with the candidate's own statements

If you're using an applicant tracking system, attach your reference check notes directly to the candidate's profile so your entire hiring team can review them.

How to Conduct a Reference Check: Step-by-Step

Running an effective reference check is about more than reading questions off a list. Here's the complete process.

Step 1: Request the right references. Ask candidates for 2–3 former direct managers — not peers, friends, or family. Former managers give the most objective, detailed feedback.

Step 2: Do your homework first. Review the candidate's resume, interview scorecard, and any notes from your hiring team before picking up the phone. This lets you ask targeted follow-up questions instead of generic ones.

Step 3: Set the tone. Start by assuring the reference that the conversation is confidential. People are far more candid when they feel safe being honest.

Step 4: Listen more than you talk. Ask your question, then wait. Resist the urge to fill silences. Some of the most revealing information comes after a pause.

Step 5: Ask follow-up questions. If a reference says "They were great," push further: "Can you give me a specific example?" If they say "They struggled with deadlines," ask: "How often, and in what context?"

Step 6: Document everything. Write down responses during or immediately after the call. Your memory of tone and nuance fades fast.

Step 7: Compare and decide. Look for patterns across multiple references. One mention of a weakness might be situational. The same weakness mentioned by two or three references is a pattern.

Red Flags to Watch For

Not every reference check goes smoothly. Here are warning signs that deserve your attention:

• The reference can't name a single accomplishment. Either the candidate didn't make an impact, or the reference barely worked with them.
• Hesitation on the rehire question. A confident "yes" is easy. Silence or qualifiers ("In the right role, maybe...") signal reservations.
• Inconsistencies with the candidate's story. If the candidate said they led a project but the reference says they were a contributor, dig deeper.
• Vague or overly positive answers to every question. References who only say "great" without specifics may be doing a favor rather than giving an honest assessment.
• The reference redirects you to HR. While some companies have strict policies, a manager who genuinely valued an employee usually finds a way to share something positive.
• The candidate can only provide peer references, not managers. This could indicate they don't have strong relationships with former supervisors.

None of these are automatic disqualifiers. But each one warrants a follow-up conversation with the candidate before you move forward.

When you track candidates through a structured hiring process, red flags from reference checks become part of the bigger picture rather than isolated data points. Tools like Tiny Team's hiring pipeline let you centralize interview notes, reference feedback, and team evaluations in one place — so nothing falls through the cracks.

Frequently Asked Questions

How many references should I check?

Two to three references per finalist is the standard. Focus on former direct managers rather than peers or personal contacts. If a candidate can't provide at least two professional references, that itself may be a concern worth addressing.

What if a reference refuses to answer questions?

Some companies have strict policies limiting references to confirming dates of employment and job title. If you hit this wall, ask the candidate for an alternative reference — ideally another former manager or senior colleague who can speak more freely.

Can I contact references the candidate didn't list?

Technically yes, but proceed carefully. Contacting a candidate's current employer without permission could jeopardize their existing job. Always ask the candidate before reaching out to anyone not on their reference list.

Should I check references for internal candidates?

Yes — even for promotions and lateral moves. Speak with their current manager and cross-functional colleagues. Internal reference checks often reveal how someone handles growth, new responsibilities, and team dynamics in ways that performance reviews alone don't capture. Your employee onboarding process should account for transitions within the company too.

Are phone or email reference checks better?

Phone calls are significantly more effective. References are more candid in conversation, and you can pick up on tone, pauses, and hesitation that written responses don't convey. Reserve email for situations where a phone call genuinely isn't possible — like international references in difficult time zones.

How long should a reference check call last?

Plan for 10–15 minutes. That's enough time to cover 8–10 questions with follow-ups. Going longer risks losing the reference's attention. Going shorter means you're probably not asking enough follow-up questions.
