Every board asks CFO candidates about strategy, investor relations, and team building. Almost none ask about the auditor. That is a mistake.
How a CFO has handled the audit relationship at their previous business is the single fastest read on their operational maturity. Here is why, and the specific questions worth asking.
Why the audit relationship is so diagnostic
Three specific reasons.
It is a relationship the CFO fully owns. Unlike investor relationships (shared with the CEO) or team building (shared with HR), the audit relationship sits with the CFO. Nothing else in the CFO's remit is as purely theirs.
It has genuine friction. Audit is one of the few CFO relationships with structural adversarial elements. The auditor's job is to find issues; the CFO's job is to represent the business's position. How the CFO handles that specific tension reveals how they handle other adversarial dynamics.
Its state at CFO exit is the residue of years of accumulated small choices. A well-run audit relationship reflects three years of good judgement calls. A strained one reflects three years of shortcuts. It is very hard to fake or catch up on.
The three questions to ask
Three questions, in order.
"Who was your audit partner at your most recent business, and how did the relationship evolve over your tenure?"
Strong CFOs name the partner, describe the initial state of the relationship, and explain how it changed. Weaker CFOs either cannot name the partner (a signal in itself) or describe the relationship in generic terms.
The specific pattern to look for: a CFO who describes deepening trust with the audit partner over three years, backed by specific examples, is a CFO who has done the relational work.
"Walk me through the most difficult audit adjustment you were pushed on. How was it resolved?"
Every CFO who has been in seat for two years has had at least one difficult audit adjustment. Strong CFOs describe it specifically: the position, the auditor's counter-position, the negotiation, the eventual resolution.
The tell is in how they describe the auditor's view. CFOs who describe it fairly (acknowledging the technical merit of the auditor's position, even where they disagreed with it) usually have healthy audit relationships. CFOs who describe the auditor as unreasonable usually have strained ones.
"If we called your audit partner tomorrow, what would they say about you?"
The killer question. Strong CFOs answer confidently and often with mild self-deprecation. "She would say I push back too hard on materiality thresholds but that we always land in a place we both accept." Weak CFOs hedge or deflect.
Then, if you can, actually call the audit partner. Auditors are usually willing to have an informal conversation with the chair of a potential next employer. The specific things to ask: was the CFO commercially minded but principled, or the reverse. Did they invest in the audit team's understanding of the business, or minimise auditor time. Would you welcome them at another engagement.
What good answers look like
The strongest audit-relationship answer we have heard in the last two years came from a CFO who is now placed at a listed business. He described the audit partner by name, described a specific technical disagreement over revenue recognition on a multi-year contract, described the auditor's position with genuine respect ("she was technically right, we disagreed on the practical judgement"), and described the resolution: a materiality adjustment both sides accepted plus a written note in the file.
He then added, unprompted: "She would tell you I push hard but I never lie."
Reference call to the audit partner confirmed the whole story, including the "never lie" framing verbatim.
What weak answers look like
Two failure modes.
The CFO cannot name the audit partner. Usually indicates the CFO delegated the relationship down (to the Financial Controller) rather than owning it. In a business where audit-committee expectations are rising (see our recent piece on audit committee chairs in 2026), this is a real gap.
The CFO frames every audit adjustment as unreasonable. Suggests the CFO treats the audit relationship as adversarial by default rather than as a partnership with genuine friction. In a listed or IPO-track environment, this pattern of thinking is expensive.
When to ask the question
Not first round. In first round the candidate is still in general-pitch mode. In second or third round, when they are more relaxed, the question elicits authentic answers.
Set it up briefly: "One thing I always ask senior finance candidates: talk me through your audit relationship." Then let them run.
