Hire a PM

Redesigned Growth PM Interview Loop

Principles: Every round tests a named criterion. Scoring happens in writing before anyone discusses. Candidate time is capped. Interviewer time is capped at two hours each.

The loop (about three weeks)

Round 1: Recruiter screen (30 min) Runs: Recruiter Tests: Evidence of shipping experiments on a weekly cadence, compensation, logistics. Explain the full loop and its time cap up front so candidates can decide early. Knockout: No recent experience running experiments with a regular cadence.

Round 2: Analytical work sample (candidate time capped at 2 hours; due within 5 days, candidate picks when) Runs: Data Analyst scores; Amara reviews. Tests: Diagnosis and experiment rigour. Brief: An anonymised trial dataset showing the 9% conversion rate. Where is the funnel leaking, what would you test first, and what would you need from Sales and Engineering? Output: A two-page memo, not a deck. One diagnosis, three ranked experiments, and one fully specified (hypothesis, primary metric, guardrail metric, sample size, engineering effort). Alternative: A 60-minute live version on a shorter dataset, for candidates who can't spare two hours. Both versions are scored on the same rubric. Interviewer time: 45 min review.

Round 3: Build session (60 min, joint) Runs: Head of Engineering and senior designer. Tests: Engineering partnership and design judgment. Can the candidate cut their top experiment to something shippable this week? Do they know what needs instrumentation and feature flags, and what the design needs to look like? Interviewer time: 60 min each.

Round 4: Influence role-play (45 min) Runs: Head of Sales. Tests: Influence without authority, and understanding of sales incentives. Scenario: Sales wants to keep manual follow-ups for trial users. The candidate needs reps to run a three-week test that changes their routine. The Head of Sales plays a realistic, sceptical rep. Interviewer time: 45 min.

Round 5: Ownership and judgment (60 min) Runs: Amara. Tests: Ownership, learning from failure, decisions on incomplete data. Format: Structured behavioural questions. Ask for three past experiments: one that failed, one where they changed a team's behaviour without authority, one decision made on incomplete data. Probe what the candidate personally did, not what the team did. Interviewer time: 60 min.

Round 6: Working norms (30 min) Runs: CEO. Tests: Candour, comfort with pace and ambiguity. This replaces "would I grab a beer with them" with defined questions: - Tell me about disagreeing with a senior leader. What happened next? - A test you championed lost. What did you do? - What pace and level of ambiguity do you need to do your best work? Interviewer time: 30 min.

Final debrief (45 min): Amara and all interviewers, using written scores.

Timeline: Days 1–2 screen and brief issued. Days 2–6 work sample. Week 2: Rounds 3–5. Week 3: Round 6, debrief within 48 hours, offer.

Interviewer load: Data Analyst about 1h; Head of Engineering and senior designer 1h each; Head of Sales 45 min; Amara about 2h 15m (Round 5 plus review and debrief; she can reduce this by handing Round 2 review to the analyst, as above); CEO 30 min plus debrief.

Scorecard

Rate each criterion 1–4. Scores of 3 or 4 are "meets bar." Criteria marked ★ are must-haves.

"Presence" and "very smart" are not criteria. Don't record them as evidence.

How we decide

1. Score before discussing. Each interviewer submits scores and written evidence before the debrief. Nobody sees others' scores first.
2. Apply the rules. Every must-have (★) needs a 3 or higher. Any 1 in any criterion is a no unless the panel explicitly discusses it. Don't average scores.
3. Debrief on evidence. Go round the table. Each person states the evidence behind their score. Discuss in depth only where scores differ by two or more points. No show of hands.
4. Amara decides. She writes a short rationale tied to the scorecard. The CEO must also score working norms at 3 or higher.
5. If still split, run one 30-minute follow-up focused on the specific gap, then decide. Don't extend the loop.
6. References. Ask referees for specific experiments the candidate ran and how they worked with Sales and Engineering.

Recommended loop

Replace the unpaid strategy deck, six-person presentation and “beer test” with structured evidence of doing this job. The previous hires’ notes cannot explain why one succeeded and one failed; cross-functional influence must be a hiring requirement, not a personality impression.

Rounds

Allow candidate questions in each assessment round. Share the format, competencies and preparation expectations beforehand; offer scheduling flexibility, breaks and reasonable accommodations. Assess reasoning and decisions, not presentation polish. The work sample is fictional, not free consulting.

Scorecard

Use 1 = clear contrary evidence, 2 = below bar, 3 = meets senior-role bar, 4 = exceptional evidence. “Not observed” is separate from a low score and must be resolved before deciding.

Interviewers record concrete actions, quotes and reasoning alongside scores. “Smart,” “great presence” and “likeable” are not evidence.

Decision, capacity and timeline

Week 1: recruiter screens and schedules two finalists. Week 2: complete assessments. Week 3: decide, close and issue the offer.

Reserve each assessor 10 minutes for calibration, five minutes per finalist for scoring, and 20 minutes for debrief. Including interviews, Engineering and the analyst each use exactly 120 minutes; Amara, Sales and Design each use 110. CEO uses at most 40 minutes. If neither finalist qualifies, reopen rather than lower the bar or silently exceed the budget.

Submit scores independently before seeing others’ notes. In debrief, review evidence competency by competency; Amara speaks last. No show-of-hands vote.

Require at least 3 on every competency, especially influence and weekly delivery. Resolve disagreements through recorded evidence, not averaging or seniority. Missing critical evidence means no offer yet. Amara owns the final decision and documents the rationale, remaining risks and onboarding support.

Growth PM interview loop

Assumptions: The two-hour cap is each person's total across all candidates, so I've designed for three finalists. Early rounds are cheap and don't use the panel's time. Only Amara's time is spent before the finalist stage.

Why the change

• The 5-day, 10-page deck cost us 14 of 40 candidates, mostly people with caregiving duties or demanding jobs. It also tests deck-making, not the job.
• The last hire failed on influencing Sales, and nothing in the old loop tested that.
• "Great presence" and "very smart" in the notes are not evidence, and a show-of-hands vote rewards the loudest voice.

The loop

Rounds 3–6 can be done in one sitting, or split across two days on video. Total candidate time is about 3 hours.

Round details - Round 1: Amara spends 5 minutes on each of about six written answers (30 min total) and picks three finalists. - Round 3: We send a one-page anonymized trial funnel 24 hours ahead, with a note to spend no more than 30 minutes on it. In the room the candidate says where they'd look first, picks two experiments, and designs one, including metric, guardrail, and what a realistic sample size allows at our volume. - Round 4: We give a half-formed experiment idea. The candidate must cut it to something shippable within a week by three engineers and a designer. The interviewers push back on scope. - Round 5: The Head of Sales plays a skeptical rep or manager who thinks trial follow-up is a distraction. The candidate has to get agreement on a small pilot. The last 5 minutes cover a real past example. - Round 6: A structured conversation covering how the candidate would think about expansion revenue for small accountancy firms, what being the first growth hire means, and a time they disagreed and then committed. This replaces "would I grab a beer."

Scorecard

Each criterion is rated 1–4, with no midpoint. Every interviewer writes specific observed behaviors, not impressions. "Presence" and "smart" don't count as evidence.

1. Influence without authority (weight 30%; Sales, plus Amara and references) - Strong: Starts from what Sales cares about (quota, time, commissions). Proposes a small, reversible pilot. Offers something in return. Has a past example where a team they didn't manage changed behavior, with details. - Weak: Says "align stakeholders." Escalates to the boss. Presents the change as a mandate. Blames other teams in past stories.

2. Conversion judgment (25%; Analyst) - Strong: Segments before theorizing. Notes that our volume limits what tests can detect. Ties each experiment to a hypothesis and a guardrail. Asks about accountancy seasonality and who actually decides to pay. - Weak: Lists generic tactics (checklists, gamification). Has no view on sample size. Doesn't ask about the data.

3. Shipping cadence (20%; Eng + Design) - Strong: Cuts scope readily to the smallest test. Gives real numbers on past experiments per week or month. Treats engineers and designers as partners and takes their objections seriously. - Weak: Proposes large projects with distant payoffs. Writes specs without hypotheses. Defends scope instead of trading it off.

4. Ownership of revenue outcomes (15%; Amara) - Strong: Gives baselines, deltas, and their specific contribution. Talks candidly about experiments that failed. - Weak: Vague credit for team results. Describes outputs (launches, decks) instead of outcomes.

5. Judgment and fit for a 60-person company (10%; CEO) - Strong: Is energized by ambiguity. Builds their own tools and doesn't wait for resources. Disagrees directly and then commits. - Weak: Needs a playbook or a team. Can't prioritize without data. Becomes defensive when challenged.

Note for the Head of Sales: Score what the candidate did in the role-play, not whether you enjoyed being challenged.

Decision process

1. Independent scoring. Each interviewer submits ratings and evidence before the debrief and can't see others' scores.
2. Debrief (20 min). Amara reads out the scores, lowest first, on each criterion. Disagreements get discussed against the evidence, not general impressions.
3. Must-haves. A score of 2 or below on influence or shipping means no offer. The last miss was an influence failure, and weak shipping defeats the weekly-experiment job.
4. Ranking. Among candidates who pass, the highest weighted score wins. Close calls go to Amara.
5. Decision owner. Amara decides, and there is no vote. The CEO can block only by citing specific observed evidence tied to the scorecard.
6. References. The recruiter checks references for the top candidate, using Amara's script. At least one reference must be a cross-functional partner such as someone from sales or marketing, asking, "Did they change how your team worked? How?"

Timeline and time budget

• Week 1: Recruiter screens and written questions. Amara picks finalists by the end of the week.
• Week 2: Amara's deep-dives, then rounds 3–6 for all three finalists.
• Week 3: Debrief on Monday, references on Tuesday and Wednesday, offer by Friday.

If more than three candidates reach round 2, Amara's time is the first limit. In that case, tighten the written screen before asking for more of her time.
