CFO: job description, interview questions, and screening workflow

The instinct is to hire the most credentialed finance person you can afford. That's the wrong first filter. A CPA license or a big-name finance background tells you someone can do the technical work. It doesn't tell you whether they'll tell you, clearly and early, that the numbers say something you don't want to hear, or whether they'll soften it until it's too late to act on. At a small business, the CFO is often the only person with full visibility into the financial reality, reporting to an owner or a board who can't independently check the work. This guide is built to screen for the judgment and the spine that role actually requires, not just the credentials.

What a CFO actually does at a small business

At a large company, a CFO sits atop a finance organization: a controller runs the close, a treasury team manages cash, an FP&A team builds the models, and the CFO synthesizes and presents. At a small business, there's rarely a team underneath. The CFO (often part-time or fractional at first) is doing strategic work personally: building the cash forecast, running the board deck, deciding what the numbers actually mean for a pricing decision or a hire, and telling the owner when a growth plan doesn't survive contact with the balance sheet.

The core responsibilities, in practice:

• Owning the cash forecast and flagging a runway problem while there's still time to act on it, not after
• Translating financial statements into decisions: whether a hire is affordable, whether a price increase is overdue, whether a big customer concentration is a real risk
• Building and defending a board or investor deck, including the numbers that don't make the story look as good
• Overseeing the accountant or bookkeeper's work without redoing it, which means knowing what a clean close actually looks like
• Setting up the financial controls a growing company needs before it's forced to by an audit or a fraud scare
• Leading fundraising, banking relationships, or a sale process when the business gets there
• Being the person in the room willing to say a plan the owner likes doesn't work, with the numbers to back it up

The technical accounting is usually not where a CFO hire goes wrong at a small business. It's the judgment layer on top: knowing which number matters this quarter, and having the standing and the nerve to put it in front of the owner even when the owner doesn't want to hear it.

CFO
[Company name] is looking for a CFO to own our financial strategy and reporting as we grow. You'll be the person who turns our numbers into decisions, and who tells us the truth about our financial position even when it's not what we want to hear.

What you'll do
Own the cash forecast and flag risk to runway with enough lead time to act. Translate financial statements into real business decisions on hiring, pricing, and growth. Build and present board or investor materials, including the numbers that complicate the story. Oversee our accounting function without duplicating the work. Put financial controls in place before we need them. Lead banking and fundraising relationships as they come up.

What we're looking for
Real experience owning financial strategy at a company our size or close to it, not just a finance title at a much larger organization. A track record of delivering hard news to an owner or a board and being right about it. Comfort working with a lean or nonexistent finance team, doing hands-on work when there's no one else to do it. Clear, plain-language communication with people who aren't finance professionals.

Schedule
[Insert full-time, fractional, or part-time cadence, and any board-meeting or close-week commitments]

[Insert pay or fractional rate, per your company's policy and any applicable state salary transparency requirements]

10 interview questions, and what a good answer sounds like

1. Tell me about a time you told an owner or a board something they didn't want to hear. What happened?

This is the single most important question on this list. A strong answer names a specific, real moment: what the numbers showed, how they delivered it, and what happened after, including any pushback. A candidate who can't produce a real example, or who describes softening bad news until it landed easier, hasn't been tested on the part of this job that matters most at a small company with no layer of protection between the CFO and the decision-maker.

2. Walk me through how you'd build a 13-week cash forecast for a business you just joined.

Listen for a real method: starting cash, expected receipts by source and timing, expected disbursements, and a clear line for what's confirmed versus assumed. A strong answer names how they'd stress-test it (a slow month, a late payment from a big customer) rather than presenting one static number. A candidate who can't describe the mechanics, only the output, may not have built one from scratch themselves.

3. A growth plan the owner is excited about doesn't pencil out on the numbers. Walk me through that conversation.

Strong answers show the candidate doing the math transparently, showing their work, and offering an alternative path rather than just a no. A candidate who says they'd "find a way to make it work" without addressing whether the underlying plan is sound is telling you they'll bend the numbers to match what's wanted, which is the opposite of what this hire is for.

4. Tell me about a control gap or a fraud risk you found and fixed at a company with a lean team.

Good answers name a specific, realistic gap (one person able to create a vendor and approve their own payment, for example) and a fix sized for a small team, not a textbook policy that assumes a large finance department. A candidate who can't name a real example may not have actually built controls under real constraints before.

5. How do you decide what to report to the owner or the board weekly, versus monthly, versus not at all?

Listen for a real prioritization framework tied to what actually drives decisions: cash position and runway probably weekly, full financials monthly, a deep variance analysis quarterly. A candidate who reports everything, all the time, hasn't thought about what the reader actually needs to act on.

6. Walk me through how you'd evaluate whether the company can afford a specific new hire.

Strong answers go beyond salary: fully loaded cost, the effect on runway, what has to be true (revenue, margin, timing) for the hire to pay for itself, and by when. A candidate who answers only with "check if there's budget" is treating this as a bookkeeping question instead of the strategic one it actually is.

7. Tell me about a time you had to work with a messy or incomplete set of books. What did you do first?

You're checking for a real triage instinct: what they'd verify first, how they'd flag what's unreliable before using it for a decision, and how they'd communicate the uncertainty rather than presenting shaky numbers with false confidence. A candidate who describes just diving in and reporting whatever the system says is a risk at a small business where clean books aren't guaranteed.

8. How would you evaluate whether our current accountant or bookkeeper's work is trustworthy, without redoing it yourself?

Listen for specific review habits: spot-checking reconciliations, reviewing the trial balance for anomalies, asking pointed questions about judgment calls rather than re-deriving every number. A candidate who says they'd "just redo it to be safe" doesn't actually scale as the company grows and isn't oversight, it's duplicated work.

9. Tell me about a fundraising, banking, or sale conversation you led. What was your role versus the owner's or CEO's?

Good answers are honest about the division of labor: the CFO usually builds the model, defends the numbers under questioning, and manages the process, while the owner or CEO leads the relationship and the pitch. A candidate who claims to have run the entire process solo, with no mention of the owner's role, may be overstating their scope on a past deal.

10. Why a small business instead of a larger finance organization with more structure and support?

This surfaces whether they understand the trade-off: more scope and influence, but also more hands-on work and less backup. A candidate who can't articulate a real reason beyond "it was the opportunity available" may be underprepared for how much of this job is personally hands-on at a company this size, not delegated to a team.

A scorecard you can score candidates against

Ten questions only help if everyone involved in the hire is listening for the same signals. Score every candidate on the same six dimensions, so you're comparing evidence instead of comparing how confident someone sounded. Copy this into a doc and fill in a row per candidate.

How to screen CFO candidates without losing a month to it

Truffle is a candidate screening platform that combines resume screening, one-way video interviews, and talent assessments, so you can build a screening workflow around what actually matters for a hire where the cost of a wrong call compounds every quarter you don't catch it.

A CFO search tends to be lower volume than most roles on this site, often a handful of serious candidates instead of hundreds of applicants, sourced through a network or a fractional CFO firm rather than a job board. That changes the shape of the workflow: less about cutting a flood down to size, more about getting deep, comparable evidence on a small number of finalists before you commit.

• Resume and reference screening first. Confirm the scope of past roles (fractional vs full-time, company size, what they actually owned) since finance titles are inconsistent across companies. Our resume screening tool flags gaps and inconsistencies worth asking about directly.
• A one-way video interview for the hard-news and judgment questions. Ask 2-3 of the scenario questions above, especially the hard-news question and the growth-plan question, so you hear how someone actually reasons and communicates before you spend a live interview on them. Our one-way video interview tool lets you compare finalists side by side on the same prompts.
• A technical fluency check as a floor, not the whole picture. Truffle's skill-based accounting test covers close-cycle scenarios, control gaps in a lean team, and an ethics-under-pressure prompt (a leader asking to move an expense to hit a target), which is a real, useful proxy for the integrity question at the center of this hire. It won't test board-level strategic judgment, which is what the interview and reference checks are for.
• Multiple, weighted reference checks. For a hire this consequential, don't skip references, and don't accept only the ones the candidate hand-picked. Ask specifically about a time this person delivered unwelcome news and how it landed.

AI surfaces the evidence and helps you compare finalists consistently. It doesn't decide who to hire. That call, more than almost any other on this site, is yours to make carefully.

Common hiring mistakes for this role

Hiring for credentials instead of demonstrated judgment. A CPA license or a big-name background is checkable and reassuring, but it doesn't test whether someone will tell you the truth when it's inconvenient. Weight the hard-news question and real references above the resume.

Waiting too long to bring on financial leadership because "we're still small." The pattern that shows up across small-business hiring generally, and finance roles specifically, is that owners hold out for a "perfect" hire or a bigger budget while decisions keep getting made on incomplete numbers. A fractional CFO a few days a month is a real, affordable first step; it doesn't have to be full-time to be worth doing now.

Letting a senior candidate skip the technical check because they "seem experienced." Seniority and confidence aren't the same as current technical fluency. A brief skills check protects you from a candidate who's coasted on strategy conversations without staying close to the mechanics.

Not testing how this person will interact with the rest of a small, thin team. A CFO who's used to a large finance department underneath them may struggle, or may quietly try to build a bigger team than you need, when the reality is hands-on work with a bookkeeper and not much else. Ask directly about their comfort with that gap.

Skipping structured references on the assumption that a strong interview is enough. This is one hire where a bad reference conversation you skipped is a mistake you'll feel for years, not months. Run them, and ask pointed questions instead of accepting a generic recommendation.
