Ask questions that force proof: show me a result with its baseline, tell me about a failure, diagnose our business out loud, explain how you will work with sales and our agencies, name the number I should judge you on, and describe how this ends. Then call references with a script. The 15 questions below cover each area.
This post is the question bank. For the full search process, see how to hire a fractional CMO. New to the role? Start with what a fractional CMO is.
Key facts
- 69% of CEOs and CFOs say failure to deliver the promised results from marketing strategy is the top reason they would remove a CMO (Gartner, February 2025). Your interview should test the promises before you hire.
- Just 22% of CEOs and CFOs say they received significant clarity from their CMO about marketing accountabilities, and only 54% feel confident in their CMO’s ability to prove marketing’s value (Gartner, February 2025).
- 90% of marketing and sales executives report that their functional priorities conflict, and the two teams typically collaborate on only three of 15 commercial activities (Gartner, June 2024).
- 59% of CMOs say they have insufficient budget to execute their strategy in 2025 (Gartner 2025 CMO Spend Survey). A candidate should be able to tell you what they would cut, not only what they would add.
- Peter Geisheker and Michael Pecora have led 300+ strategy sessions with CEOs. The questions below are the ones we would want a CEO to ask us.
Track record and proof
Most candidates will say they “drove growth.” These questions make them show the math.
1. “Walk me through one engagement where the numbers moved. What was the baseline, what did you change, and what happened?”
Why ask it: A result without a starting point is a claim, not proof.
A strong answer sounds like: A specific before and after (“cost per qualified opportunity went from X to Y over two quarters”), the two or three decisions that caused it, and what they would do differently. They can protect client names and still give real numbers. Peter’s career results include 6X inbound lead growth and a 77% reduction in paid acquisition costs, and he explains the changes behind each without naming companies.
2. “Tell me about an engagement that did not work. What did you get wrong?”
Why ask it: Everyone senior has had one. How they talk about it tells you how they will act when your plan stalls.
A strong answer sounds like: A real miss, owned in the first person, with the lesson they now apply. “The client wasn’t ready” with nothing else is not an answer.
3. “In the result you just described, what was already in motion before you arrived?”
Why ask it: It tests attribution honesty. A new product release, a price change, or a big new sales hire can make any marketer look good.
A strong answer sounds like: They separate their impact from the tailwinds without being asked twice, and they say how they measured the difference.

How they diagnose your business
You want someone who asks before they prescribe. These questions show whether a plan comes from your data or from their last client.
4. “What do you need to see in the first 30 days, and what will you refuse to recommend until you have it?”
Why ask it: It shows whether they have a real diagnostic process or a template.
A strong answer sounds like: A specific list: closed-won and closed-lost deals by source, CRM stage history, win rates, sales cycle length, current spend by channel, and a few customer conversations. Then a clear line: “I won’t recommend new channels until I know where your best customers actually came from.”
5. “Based on this conversation, what is your working hypothesis about our biggest constraint, and what would prove you wrong?”
Why ask it: A senior operator forms hypotheses fast and holds them loosely.
A strong answer sounds like: One focused hypothesis (for example, “your problem is conversion from meeting to opportunity, not lead volume”) plus the exact data that would kill it.
6. “Which marketing would you stop funding first, and how would you decide?”
Why ask it: Budgets are tight, so subtraction often matters more than addition.
A strong answer sounds like: A rule tied to revenue, such as cutting any channel that cannot be traced to pipeline after a fair test window. Every program should carry a response mechanism so it can be measured.
How they work with your team, sales, and agencies
Most fractional CMO engagements fail at the seams between people, not in the strategy deck.
7. “Our head of sales says marketing leads are junk. What do you do in the first month?”
Why ask it: Sales and marketing conflict is the norm, not the exception, per the Gartner data above.
A strong answer sounds like: They sit with sales, listen to calls, agree on a written definition of a qualified lead, and set up a shared weekly review of what happened to every lead. They side with the data, not with either team.
8. “How would you evaluate our current agency, and what would make you recommend replacing them?”
Why ask it: You need someone who will hold vendors accountable, not protect them or replace them by reflex.
A strong answer sounds like: Judge the agency on business results tied to pipeline, check whether the agency reports on the numbers that matter, and give them a clear brief and a fair window before deciding.
9. “Do you receive referral fees, markups, or commissions from any agency, software, or vendor you might recommend?”
Why ask it: A hidden incentive changes every recommendation that follows.
A strong answer sounds like: A plain “no,” or full disclosure in writing with the client’s right to choose another option.
10. “Who would you lead directly, and which decisions do you need authority over to do this job?”
Why ask it: A fractional CMO with no authority becomes an expensive advisor.
A strong answer sounds like: A clear list: the marketing budget, agency direction, the marketing team’s priorities, and a seat in the leadership meeting. They also say what stays with you.
Measurement and accountability
11. “What numbers will you report to me every month, and which single number should I judge you on?”
Why ask it: Only 22% of CEOs and CFOs say their CMO gave them significant clarity on marketing accountabilities (Gartner). Get that clarity before you sign.
A strong answer sounds like: A short report built on pipeline, cost per qualified opportunity, and revenue sourced or influenced, with one primary number agreed in writing.
12. “Our deals take six months or more to close. How will we know marketing is working before revenue shows up?”
Why ask it: Long B2B cycles are where weak marketers hide.
A strong answer sounds like: Leading indicators that are proven to predict revenue in your funnel (qualified meetings held, opportunities created, stage conversion rates), checked against closed revenue as it arrives.
13. “What will be different at day 90, specifically, and how will I know earlier if it is not working?”
Why ask it: It turns a vague promise into a commitment you can check.
A strong answer sounds like: Named deliverables and target metrics for day 90, plus early warning signs at 30 and 60 days. Our own engagements start with a 90-day sprint for exactly this reason.
Fit and exit
14. “What kind of company or CEO is a bad fit for you?”
Why ask it: A candidate who says everyone is a fit has not thought hard about where they win.
A strong answer sounds like: A specific answer: company size, stage, sales motion, or a CEO behavior (for example, a CEO who wants to approve every ad).
15. “How does this engagement end, and what will we own when you leave?”
Why ask it: The best fractional CMOs plan their exit from day one.
A strong answer sounds like: You own every account, dashboard, piece of content, and playbook. They describe the handoff: hiring or training a full-time leader, or a documented system your team can run. For how the role compares with a permanent hire, see fractional vs full-time CMO vs agency.

Reference-check script
Ask the candidate for two references from CEOs and, if possible, one from a head of sales who worked alongside them. Then use this script on each call.
- “What was the business problem when they started, and what were the numbers then?”
- “What were the numbers when they finished, and how much of that change would you credit to them?”
- “What did they get wrong, and how did they handle it?”
- “How did your sales team feel about them after the first 90 days?”
- “Did they hold your agencies and vendors accountable, or defer to them?”
- “Were their monthly reports useful to you, or did you have to ask for what you needed?”
- “Would you hire them again for the same problem? For a different one?”
- “Who else at your company worked with them that I should talk to?”
Listen for hesitation on questions 2 and 7. A reference who cannot name a number is telling you something.
Frequently asked questions
How many of these questions should I ask in a first interview?
Pick six to eight across all five groups and save the rest for a second meeting. Always include questions 1, 5, and 11. Proof, diagnosis, and accountability separate senior operators from good talkers fastest.
Should I share company data with a candidate before hiring them?
Share enough for question 5 to be meaningful: a summary of pipeline by source, win rates, and spend by channel. Use an NDA if you need one. A candidate who gives you a sharp hypothesis from a light data set is showing you how they will work.
How do I verify results when a fractional CMO cannot name past clients?
Ask for the baseline, the change, and the time frame, then confirm the story on reference calls. Confidentiality is normal. Refusing to share any numbers at all is not.
Who from my team should join the interview?
Bring your head of sales for questions 7 and 12, and your CFO or finance lead for questions 11 and 13. Their reactions to the answers matter as much as yours, because they will work with this person every week.
Should cost come up in the interview?
Yes, but after you have tested competence, so price does not color how you hear the answers. For how fees are structured, see how fractional CMOs charge for their services.
