Direct Answer

The 15 interview questions that actually separate a strong fractional CRO from a weak one are: (1) "Walk me through your forecast accuracy at your last engagement — how did you measure it and what was the variance?", (2) "Show me the last 90-day plan you delivered to a CEO — what artifacts came out of Days 1-30, 31-60, 61-90?", (3) "What is your engagement load right now — how many clients, how many days per week, and how do you handle conflicts?", (4) "Describe the last engagement that failed and what you would do differently", (5) "What is your qualification framework — MEDDPICC, Command of the Message, Sandler, BANT, or your own — and why?", (6) "Walk me through a comp plan you rebuilt — base/variable split, accelerators, decelerators, and the CFO conversation", (7) "How do you handle a VP of Sales who resists your changes?", (8) "What is your board-meeting cadence — how often, what artifacts, and what tone with the directors?", (9) "How do you hire the VP of Sales who eventually replaces you?", (10) "What GTM stack do you typically install or rely on — CRM, forecasting, enablement, conversation intel, intent data?", (11) "Describe how you align marketing and CS with sales — specific mechanism, not theory", (12) "What is your success metric for this engagement and how would we measure it together?", (13) "How do you handle a missed quarter — what is your first move with the team and the board?", (14) "Show me a board deck revenue slide you have built", (15) "What is your exit criteria — when do you tell the CEO it's time to transition you out?" These questions probe operating depth (1, 2, 6, 11, 13), scope and seniority (8, 14), realism and humility (3, 4, 7, 15), methodology (5, 10), and alignment with the company's stage (9, 12).

Use them as a rubric — strong operators answer specifically with examples from named companies; weak ones give frameworks without artifacts.

1. Questions that probe operating depth

The biggest separator is whether the operator can show real artifacts vs. Talking in frameworks and theory.

1.1 Forecast accuracy

Q1: "Walk me through your forecast accuracy at your last engagement — how did you measure it and what was the variance?"

Strong answer: Names a specific company, specific tool (Clari, Gong Forecast, BoostUp, or Salesforce native), specific cadence (Monday/Wednesday/Friday), and specific variance numbers ("we landed within 4% of commit for 5 of 6 quarters"). Weak answer: vague — "we focused on forecast discipline."

1.2 The 90-day plan artifact

Q2: "Show me the last 90-day plan you delivered to a CEO — what artifacts came out of Days 1-30, 31-60, 61-90?"

Strong answer: Pulls up the actual plan (redacted) and walks you through specific deliverables — GTM assessment, qualification scorecard rollout, comp plan rebuild, ICP refresh, VP Sales job spec. Weak answer: describes the framework but cannot produce an artifact.

1.3 Comp plan rebuild

Q6: "Walk me through a comp plan you rebuilt — base/variable split, accelerators, decelerators, and the CFO conversation."

Strong answer: Names the base/variable split (e.g., 50/50, 60/40), the accelerator curve ("2x above 100% attainment, 3x above 130%"), the decelerator ("0.5x below 70%"), the kicker (President's Club at 120%+), and which tool ran it (CaptivateIQ, Performio, Spiff, Xactly).

Crucially, names the CFO conversation — the negotiation about the cost-of-plan ratio (typically 8-12% of bookings).

1.4 Cross-functional alignment

Q11: "Describe how you align marketing and CS with sales — specific mechanism, not theory."

Strong answer: Names a specific mechanism — joint ICP scorecard, weekly MQL-to-SQL conversion review, monthly revenue council with VP Sales/VP Marketing/CS lead, shared net revenue retention KPI, etc. Weak answer: "we made sure they were aligned."

1.5 Handling missed quarters

Q13: "How do you handle a missed quarter — what is your first move with the team and the board?"

Strong answer: Specific sequence — (1) honest board update with named gap drivers, (2) win/loss readout on slipped deals from Gong call data, (3) rep-by-rep pipeline rebuild for the next quarter, (4) named action plan with owners and dates. Weak answer: "we focused on accountability."

2. Questions that probe scope and seniority

2.1 Board cadence

Q8: "What is your board-meeting cadence — how often, what artifacts, and what tone with the directors?"

Strong answer: Monthly board update memos plus quarterly board meeting deck, with named artifacts — revenue slide, pipeline coverage chart, comp plan attainment distribution, retention waterfall. Names the tone — "I write the slide myself; the CEO presents it; I take 3-4 questions."

2.2 The board deck artifact

Q14: "Show me a board deck revenue slide you have built."

Strong answer: Has one ready (redacted) and walks through the 6-8 KPIs they put on it — ARR, net new ARR, NRR, GRR, pipeline coverage, CAC payback, win rate, rep ramp time. Weak answer: never built one personally.

3. Questions that probe realism and humility

3.1 Engagement load

Q3: "What is your engagement load right now — how many clients, how many days per week, and how do you handle conflicts?"

Strong answer: Specific — "3 clients, 12 days/month allocated, hard cap at 5 concurrent." Names conflict handling ("I disclose competitive overlap up front; I will not take two companies in the same ICP"). Weak answer: vague or claims unlimited capacity.

3.2 Failed engagement

Q4: "Describe the last engagement that failed and what you would do differently."

Strong answer: Names a real failure — "the CEO was not willing to replace the VP Sales who was the actual problem; I should have walked at Day 60 instead of staying 9 months." Weak answer: "I have never had one fail" (red flag) or blames the client without self-reflection.

3.3 Resistant VP of Sales

Q7: "How do you handle a VP of Sales who resists your changes?"

Strong answer: Specific sequence — shadow + joint customer calls for 30 days, name the resistance to the CEO at Day 45, give the VP one explicit chance to come along, recommend replacement at Day 60 if needed. Weak answer: "build trust" with no concrete steps.

3.4 Exit criteria

Q15: "What is your exit criteria — when do you tell the CEO it's time to transition you out?"

Strong answer: Names the trigger — typically "when the full-time VP Sales is hired and ramped, or when ARR crosses $X." Mentions the handoff plan (90 days of part-time mentoring of the new hire). Weak answer: "as long as you need me" (red flag — operator wants permanent retainer).

4. Questions that probe methodology

4.1 Qualification framework

Q5: "What is your qualification framework — MEDDPICC, Command of the Message, Sandler, BANT, or your own — and why?"

Strong answer: Names a specific framework, explains where they have rolled it out, and acknowledges trade-offs (MEDDPICC is heavy for SMB, BANT is too thin for enterprise, etc.). Weak answer: claims to be "framework-agnostic" or "uses a custom approach."

4.2 GTM stack

Q10: "What GTM stack do you typically install or rely on — CRM, forecasting, enablement, conversation intel, intent data?"

Strong answer: Named tools — Salesforce or HubSpot (CRM), Clari/Gong Forecast/BoostUp (forecasting), Gong/Chorus (conversation intel), 6sense/Demandbase/Bombora (intent), Outreach/Salesloft/Apollo (engagement), CaptivateIQ/Performio (comp), Mindtickle/Spekit (enablement).

Names what they would replace if the current stack is wrong.

5. Questions that probe stage alignment

5.1 Hiring the VP Sales replacement

Q9: "How do you hire the VP of Sales who eventually replaces you?"

Strong answer: Walks through the JD writeup, recruiter selection (often TrueBridge, Daversa, Heidrick & Struggles, Russell Reynolds, or Korn Ferry for senior; Better.com or SaaS Sales Hires for VP-level), interview loop design, and the 30/60/90 ramp plan. Names typical search time (4-6 months) and budget.

5.2 Engagement success metric

Q12: "What is your success metric for this engagement and how would we measure it together?"

Strong answer: Co-designs the metric with you — typically forecast accuracy within 5%, pipeline coverage at 3x sustained, VP Sales hired and ramped by month 9, founder out of every deal by month 6. Names how it gets measured monthly with the CEO. Weak answer: vague — "we will know it when we see it."

FAQ

Q: How long should the fractional CRO interview loop be? 3-4 conversations over 2 weeks. (1) CEO intro call (60 min), (2) deep working session (90 min, walks through 90-day plan), (3) team meet (VP Sales, VP Marketing, CFO — 30 min each), (4) reference calls (3 prior CEO clients).

Q: Should I ask for references? Yes — 3 prior CEO references, ideally companies in the same stage and ARR band. Ask the references: "Would you hire them again? What did they get wrong? Who replaced them?"

Q: What's the single biggest red flag? Claims of never having had a failed engagement. Every senior operator has had at least one engagement that did not work. Inability to name one signals either inexperience or lack of self-awareness.

Q: Should I ask about firm affiliation? Yes. Operators at firms like CRO Syndicate, Sales Xceleration, or Chief Outsiders often have bench coverage if they become unavailable. Independents do not. This matters for risk mitigation.

Q: Can I negotiate the retainer? Yes — typical levers are day commitment (3 days instead of 4 drops retainer 20-25%), multi-quarter commitment (6-12 month commitment earns 10-15% off), and equity swap (0.1%-0.25% advisory equity in exchange for $2K-$5K of monthly cash).

Bottom Line

Use the 15 questions as a rubric to separate strong fractional CROs (specific answers with named artifacts and named companies) from weak ones (frameworks without examples, vague metrics, no failures). The five highest-signal questions: Q1 (forecast accuracy with numbers), Q2 (the actual 90-day plan artifact), Q4 (a real failure), Q14 (a real board deck slide), Q15 (genuine exit criteria).

Source candidates through CRO Syndicate, Sales Xceleration, Chief Outsiders, Pavilion Helm, Winning by Design, or Force Management Consulting, or via the Pavilion member directory for independents. Run a 3-4 conversation loop over 2 weeks with 3 CEO references — and walk away from anyone who cannot show their work.
