A startup head of product interview works best in four stages: a CEO screen, a product deep dive with the CTO, a strategy memo review, and a disagreement session with the CEO before references. The last stage tests whether real decisions can move from founder to hire.
Our rule is to interview the handover as well as the candidate. In the final stage, the CEO and candidate argue about a real roadmap decision from the past. You learn whether the candidate holds a position under pressure, and whether the CEO can stand to give the call away.
Our illustrative example: a carbon accounting software startup selling to manufacturers, moving from Seed to Series A. The founder-CEO, who has owned product since day one, is interviewing Daniel, a group PM from a larger B2B company.
| Stage | Who | Length | What it tests |
|---|---|---|---|
| 1. CEO screen | CEO | 45 min | Motivation, stage fit, which decisions they expect to own |
| 2. Product deep dive | CTO plus a senior engineer or PM | 60 min | Past product calls, technical depth, working with engineering |
| 3. Strategy memo review | CEO, CTO and a board member or advisor | 75 min | Written strategy, prioritisation, handling sceptics |
| 4. Disagreement session and references | CEO, then reference calls | 60 min plus calls | Decision rights, holding a position, founder partnership |
Put stage 4 in the diary before stage 1 starts. Founders who leave it to the end tend to shorten it when they like the candidate.
Strong answer: A strategy sentence that rules things out, and at least one thing in your product they would stop.
Red flags: A strategy that is a list of features, or no view on what to stop.
Asked question 1, Daniel said the strategy was "win mid-size manufacturers who must report emissions to their customers, and ignore those reporting voluntarily", and the roadmap was "supplier data import first, because those buyers can't report without it". That scores 4 on roadmap and strategy, because the strategy excludes a segment and the roadmap follows from it. A 2 describes the roadmap twice.
Strong answer: A specific overrule they accepted, and decisions they would leave with you without being asked.
Red flags: Every past CEO was the problem, or they want full control before meeting customers.
Strong answer: A hiring scorecard they wrote, and a managing-out story that admits the cost to the team.
Red flags: Hiring by gut feel.
Strong answer: One or two numbers linked to revenue, a pricing story with the result, and a fix for the sales process rather than a lecture.
Red flags: Vanity metrics, or treating sales as the enemy.
Share a short pack: anonymised top customer requests, this year's goals and one constraint, such as engineering capacity. Ask for where to focus for 12 months, three things to stop, the first roadmap quarter and one decision they want from the CEO. Cap it at 3 hours.
Look for choices that exclude customers and a roadmap that follows from them. Daniel asked for the final say on which integrations get built, which told the CEO exactly where the friction would be.
The memo then feeds the stage 4 disagreement session.
| Outcome | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| Decision rights | Wants all or nothing | Accepts whatever is given | Proposes a clear split | Proposes a split and an escalation rule |
| Roadmap and strategy | Feature list | Strategy and roadmap unconnected | Roadmap follows strategy | Strategy rules out real options |
| PM team | Never hired PMs | Hired with help | Hired and developed PMs | Built a team that runs without them |
| Product results | Measures shipping | Measures usage | Measures customer results | Killed features on evidence |
| Board and investors | No board exposure | Supported the CEO | Presented to a board | Changed a board's mind |

Yes. Only the CEO can test whether they will hand decisions over.
Ask a former CEO which decisions they stopped making after the candidate joined. Vague answers are a warning.
