A fractional CFO interview isn't about grilling candidates on technical accounting knowledge. It's about understanding whether this person can help you make better decisions, communicate effectively with your team and investors, and actually solve the problems you're facing.

These 15 questions are designed to reveal the things that matter most: relevant experience, communication style, strategic thinking, and cultural fit. Use them as a framework, not a rigid script—the best interviews feel like conversations.

Before You Start

Make sure you've clearly defined what you need before interviewing. Review our guide on How to Hire a Fractional CFO for the full hiring framework.

Experience & Background Questions

1. "Tell me about your experience with companies at our stage and in our industry."

This is your most important question. A fractional CFO who's worked with similar businesses will ramp up faster and provide more relevant advice.

Look for: Specific examples with company names (with permission), revenue ranges, and challenges faced. Vague answers like "I've worked with lots of similar companies" are a yellow flag.

2. "What does your typical client engagement look like?"

Understand their working style and what you're actually getting. Some fractional CFOs are hands-on; others are advisory only.

Look for: Clear description of regular activities, meeting cadence, deliverables, and communication patterns. The answer should match what you need.

3. "How many clients do you currently work with, and how do you manage your time?"

This reveals whether they have adequate bandwidth for you. Overextended fractional CFOs are a common source of disappointment.

Look for: Most fractional CFOs work with 3-6 clients. More than that should raise questions. They should also explain how they prioritize when multiple clients need attention.

4. "Can you share an example of a difficult financial situation you helped a client navigate?"

Real experience shows through specific stories. This also reveals how they handle pressure and complexity.

Look for: A specific, detailed story with a clear problem, their role in solving it, and the outcome. Bonus points if they acknowledge what they learned or would do differently.

Approach & Problem-Solving Questions

5. "What would your first 30 days look like working with us?"

A structured onboarding approach indicates experience. They should have a process for getting up to speed efficiently.

Look for: A clear plan involving financial assessment, stakeholder meetings, system review, and quick win identification. Generic "I'll learn your business" answers aren't good enough.

6. "Here's a challenge we're facing: [describe real problem]. How would you approach it?"

This is the most revealing question. Present a real challenge—pricing decision, cash flow concern, or strategic choice—and see how they think.

Look for: They should ask clarifying questions before jumping to solutions. Their approach should be structured and logical. Beware of candidates who immediately claim to have the answer.

7. "What financial tools and systems do you typically recommend or use?"

This reveals their technical comfort and whether they stay current. It also helps you understand implementation expectations.

Look for: Familiarity with modern tools (QuickBooks, Xero, financial modeling tools) but also flexibility. They shouldn't insist you switch everything to their preferred stack.

8. "How do you approach situations where you disagree with the CEO or leadership team?"

A good fractional CFO should push back when needed, not just tell you what you want to hear. This question reveals their advisory style.

Look for: Evidence they'll be direct and honest while remaining respectful. They should be able to give an example of a time they disagreed and how they handled it.

Communication & Working Style Questions

9. "How do you typically communicate with clients? What's your response time?"

Misaligned communication expectations cause major friction. Establish this upfront.

Look for: Clear, specific expectations. "I respond to emails within 24 hours and am available for urgent calls" is better than vague promises of availability. Their preference should match yours.

10. "How do you explain complex financial concepts to non-finance people?"

Your fractional CFO needs to communicate with your whole team, not just other finance people. Jargon-heavy communication is a problem.

Look for: Ask them to explain something during the interview—like how to think about pricing or unit economics—and see if they can do it clearly. The interview itself is a test of their communication skills.

11. "What do you need from me to be successful in this role?"

This flips the interview and reveals their self-awareness and working style. It also sets expectations for your responsibilities.

Look for: Specific, reasonable requests: access to systems, regular meeting time, responsiveness to questions, support for implementing changes. Vague answers suggest lack of experience.

Practical & Logistics Questions

12. "Walk me through your pricing and what's included vs. additional."

Understand exactly what you're paying for. Hidden costs or unclear scope create problems later.

Look for: Transparent pricing with clear scope. They should be able to explain what's included in the base retainer and what would be additional. Red flag: reluctance to discuss pricing directly.

13. "What happens if we need to scale up or down the engagement?"

Your needs will change. Understand the flexibility of the arrangement.

Look for: Reasonable flexibility. Most good fractional CFOs work month-to-month with 30-day notice. Be wary of those pushing for long-term commitments upfront.

14. "Can you provide references from current or recent clients?"

References are essential. Speaking to other clients gives you unfiltered insight.

Look for: Willingness to provide 2-3 references from relevant clients (similar stage/industry). Hesitation or excuses about confidentiality are concerning—any professional should have clients willing to speak on their behalf.

15. "What questions do you have for me?"

This is as important as any other question. A good fractional CFO should be evaluating you as much as you're evaluating them.

Look for: Thoughtful questions about your business, goals, challenges, and what you're hoping to achieve. If they don't have questions, they're either not engaged or not thorough—both are problems.

What to Listen For Throughout the Interview

Beyond specific answers, pay attention to these patterns:

Positive Signs

They ask clarifying questions before answering
They give specific examples, not generalizations
They acknowledge what they don't know
They push back thoughtfully on your assumptions
They seem genuinely curious about your business
They explain things without excessive jargon

Warning Signs

They talk more than they listen
Every answer sounds rehearsed or generic
They promise results without understanding your situation
They avoid direct answers to direct questions
They seem unfamiliar with your industry or stage
They don't have questions for you

Trust Your Instincts

You'll work closely with this person on important decisions. If something feels off—even if you can't articulate what—pay attention. Chemistry and trust matter as much as credentials.

Bonus: Questions for Reference Checks

When you speak with their references, ask these questions:

"How would you describe their communication style?"
"What was the most valuable thing they did for you?"
"Were there any areas where they fell short of expectations?"
"How did they handle disagreements or pushback?"
"Would you hire them again? Why or why not?"
"Is there anything I should know that I haven't asked about?"

Listen not just to what they say but how they say it. Enthusiastic recommendations are very different from lukewarm ones, even if the words are similar.

Frequently Asked Questions

How many questions should I ask in a fractional CFO interview?

Plan for 8-12 questions in a 60-minute deep-dive interview. This allows enough time for follow-up questions and conversation. Don't rush through a checklist—the discussion around each question often reveals more than the initial answer.

Should I share my financials before the interview?

Share a high-level summary (revenue range, team size, industry) but save detailed financials for after you've decided to work together. Good fractional CFO candidates will ask smart questions without needing to see your books first. Sharing too much too early also creates confidentiality concerns.

What if a candidate can't answer a question?

How they handle questions they can't immediately answer is revealing. A good response: 'I haven't encountered that specific situation, but here's how I'd approach it...' A bad response: dismissing the question or pretending to know something they don't. Intellectual honesty matters.
