Before you hire
What should I ask a fractional CMO in an interview?
Skip the resume questions. Every question that matters tests one thing: does this person diagnose before they prescribe? I'm Daniel Fox, a fractional B2C CMO. Anyone who tells you the first thing they would do, before they have seen your creative, your analytics, and your positioning, is selling a playbook. Ask the questions that surface judgment, not a rehearsed plan.
The tell: a plan offered before anyone has looked
The worst answer a candidate can give is the confident one. Anyone who walks in already knowing the first thing to do, when that first thing is not learning your creative, your analytics, and your current positioning, is selling a playbook. From outside your company, the data and the customer understanding are opaque. Nobody without access to what is currently being done, in extreme detail, can responsibly prescribe anything. So the prescription is not yours. It is the one they hand to everyone.
The right first move is research, research, research. Not only the company's own prior work and how it performed, but the entire market it competes in. An honest CMO will describe a real onboarding period, an incubation where they absorb what has been tried before they commit to a single change.
Anybody that would say they know what to do prior to looking is not somebody that I would trust with my company.
Ask what happens in month one
This is the question that separates a leader from a vendor. The wrong answer is a week-one action list. The right answer is a baseline and a round of conversations. In the first month a real CMO documents what is happening before touching it: every campaign and who it targets, your cost to acquire a customer, your traffic sources, how each campaign performs on its own, returns, time to purchase, and your search performance across SEO and the newer AI and generative answer surfaces.
That baseline is not busywork. It is the fence that later lets you tell which results came from the new work and which came from referrals or seasonality. A candidate who skips it cannot answer the only question that matters at the end: was it worth it.
Ask what they refuse to do
A good fractional CMO can name the work they will not take on, in three kinds. Some work genuinely needs execution investment to move a number: media production, PR, press releases. Those channels are not always optimizable on a budget of zero, so an honest CMO will not promise results on them without the spend behind them. Some refusals are ethical. I will not misrepresent a product or a brand promise, because that is bad for everyone, the brand included. And some work is simply a misuse of the seat. It should be delegated, not done by the person you are paying to decide.
Then listen for the flip. A candidate who refuses nothing is the red flag, not the green one. It usually means one of two things: they do not know the edges of their own capabilities, or they are over-promising to win a job that is not a good fit. The CMO who names exclusions is showing you self-knowledge. The one who says yes to everything will answer for nothing.
Ask what they actually believe
A CMO with no positions you could disagree with has no positions at all. So ask one directly: which of your beliefs has cost you a deal? If the answer is smooth and agreeable, you are talking to someone who will agree with you straight into the plateau you are already on.
Here is mine, the one that costs me work. I am a first-principles thinker, and the deals I lose are to founders who want to borrow a competitor's strategy. Borrowing a strategy is borrowing legitimacy. It feels safe because someone else is already doing it, but it skips the only question that matters, whether that strategy fits this company, this customer, and this market, right now. I will always invite a founder into that conversation, but if they are committed to copying rather than testing, I will walk away. You can read the rest of what I hold to be true on my beliefs page, and a candidate worth hiring should be able to hand you their own version without flinching.
