TL;DR
Practical checklist and templates to hire a Growth Marketing Manager who can run experiments, analyze funnels, and drive acquisition and retention.
Role Overview
A Growth Marketing Manager designs, runs, and scales experiments across the funnel to drive sustainable user and revenue growth. They blend analytics, creative testing, product sense, and lifecycle marketing to find repeatable channels and optimize conversion. This role sits at the intersection of product, marketing, and data teams and requires both strategic thinking and hands-on execution.
What That Looks Like In Practice
Running multi-variant landing page tests that increase trial conversion, building an onboarding email/drip sequence that improves activation rates, launching paid acquisition campaigns with optimized creative and bidding rules, and partnering with product to A/B test feature flows that increase retention. A strong candidate will own a KPI (e.g., New Paying Customers / CAC / LTV) and iterate toward scale.
Core Skills
These are the technical and domain skills that enable a Growth Marketing Manager to move the needle.
- Experiment Design & A/B Testing Ability to design valid experiments, choose metrics, calculate sample sizes, and interpret results to inform next steps.
- Analytics & Data Literacy Comfort with analytics tools (Mixpanel, Amplitude, GA4) and SQL for slicing cohorts, funnel analysis, and measuring causal impact.
- Paid Acquisition Hands-on experience running campaigns on Meta, Google Ads, TikTok, LinkedIn or programmatic channels, including creative testing and bid strategy.
- Lifecycle & Email Automation Experience building onboarding, retention and win-back flows using tools like Braze, Iterable, Klaviyo, or HubSpot.
- Product Sense Ability to identify product-led growth opportunities, propose onboarding/product experiments, and align with PMs on implementation.
- Creative & Copy Collaboration Knows how to brief designers/copywriters, iterate on ad creative, and read creative performance to drive improvements.
- Technical Fluency Comfort working with engineering and analytics teams; understands tracking, event instrumentation, and data pipelines.
Prioritize candidates who demonstrate both depth in a couple of these areas and working familiarity across the rest.
Soft Skills
Growth roles are cross-functional and iterative. These behavioral attributes predict success.
- Curiosity & Hypothesis-Driven Asks good questions, forms clear hypotheses, and prioritizes experiments based on expected value and learnings.
- Bias for Action Moves quickly from idea to test, comfortable shipping imperfect experiments and learning fast.
- Communication & Stakeholder Management Can present findings, build alignment across product/engineering/design, and translate data into clear recommendations.
- Problem-Solving & Adaptability Handles ambiguity, pivots when experiments fail, and iterates based on evidence.
- Ownership & Results Orientation Owns KPIs, understands unit economics, and demonstrates persistent focus on growth outcomes.
Look for concrete examples that demonstrate these skills in prior roles or projects.
Job Description Do's and Don'ts
A clear job description attracts the right candidates and weeds out misfits. Use language that is specific and outcome-oriented.
| Do | Don't |
|---|---|
| Specify the primary growth KPI the role will own (e.g., new trial conversions, MQL-to-paid conversion). | List vague responsibilities like “help with marketing” without measurable outcomes. |
| Call out required tools and skills (e.g., SQL, Amplitude, Meta Ads) and which are nice-to-have. | Combine Growth Manager with unrelated full-stack product or design duties that dilute ownership. |
| Mention the team structure and cross-functional partners (PMs, analysts, design). | Use buzzwords without context (e.g., “growth hacker” with no clarity on expectations). |
Be explicit about seniority, ownership, tools, and the primary KPI the role will own.
Sourcing Strategy
Target candidates who’ve shipped repeatable acquisition or retention plays at similar stage businesses (startup, scale-up, enterprise). Use a mix of passive outreach, community sourcing, and job ads.
- LinkedIn & Outreach Search for titles like Growth Marketing Manager, Performance Marketing Manager, or Product Growth at similar-stage companies. Personalize outreach with a specific growth challenge you’re hiring to solve.
- Product & Analytics Communities Source from communities and meetups (GrowthHackers, ProductLed, local analytics groups) where hands-on practitioners share experiments and case studies.
- Referrals from PM/Eng/Marketing Ask your product and analytics teams for referrals—people who’ve worked cross-functionally are often the best fits.
- Portfolio & Case Study Requests In outreach, ask for a short case study or a link to a public write-up of a growth experiment to quickly assess rigor and outcomes.
- Job Boards & Ads Use targeted job ads on platforms frequented by marketers (Angellist, Indeed, LinkedIn) with clear KPIs and expected impact to improve applicant quality.
Prioritize demonstrated growth outcomes over job titles.
Screening Process
A tight screening process saves time and surfaces candidates who can both think and execute.
- Resume & Portfolio Triage Screen for relevant experiments, measurable outcomes (improved CVR, lowered CAC, increase in LTV), and tools/SQL experience. Request a 1-page case study for strong candidates.
- Recruiter Screen (30 minutes) Assess role fit, motivations, availability, compensation expectations, and high-level examples of owned growth outcomes.
- Hiring Manager Technical Screen (45–60 minutes) Dive into one or two past experiments: hypothesis, setup, sample size, metric calculations, tooling, results, and next steps. Confirm SQL or analytics chops if required.
- Skills Assignment (take-home or live) Short take-home: analyze a funnel dataset or design a growth experiment and roadmap. Limit to 3–6 hours maximum and evaluate for reasoning, prioritization, and clarity.
- Cross-Functional Interview Panel Include PM, data analyst, and designer/creative partner to assess collaboration, technical fit, and ability to translate insights into product or creative changes.
- Final Cultural & Leadership Fit Interview with a senior leader to confirm strategic alignment, ownership mentality, and compensation/expectations fit.
Keep each stage time-boxed and objective-focused to reduce bias and speed to offer.
Top Interview Questions
Q: Describe a growth experiment you led that failed. What did you learn and what did you do next?
A: Look for clear hypothesis framing, how failure was measured, lessons extracted, and subsequent experiments. Strong answers show learning loops and adaptation rather than defensiveness.
Q: Give an example of a funnel you optimized. What metrics did you choose and what tools did you use to measure impact?
A: Candidate should articulate north-star and leading metrics, analysis approach (cohorts, segmentation), tools used, and causal reasoning for observed changes.
Q: How do you decide which growth experiments to prioritize?
A: Expect a framework (ICE, RICE, expected value) and demonstration of trade-offs between learnings, impact, and cost/time to implement.
Q: Walk me through an acquisition channel you scaled. What creative and targeting changes materially moved performance?
A: Good responses include clear before/after metrics, creative iterations, audience segmentation, and how incrementality or saturation was measured.
Q: How comfortable are you with SQL/analytics? Give an example of a question you answered with SQL.
A: Strong candidates can describe a concrete query-driven analysis, why it was necessary, and how it changed the team’s decisions.
Q: How do you partner with product and design on growth experiments?
A: Look for collaborative processes: shared hypotheses, lightweight prototypes, instrumentation standards, and post-experiment retrospectives.
Top Rejection Reasons
Deciding rejection reasons ahead of interviews helps interviewers consistently screen for misalignment.
- No measurable outcomes Candidate cannot point to specific metrics improved or gives only vague, unquantified descriptions of work.
- Weak experiment rigor Unable to explain hypothesis testing, sample size considerations, or how they controlled for confounding factors.
- Insufficient analytics skills Lacks basic SQL/analytics experience when role requires it, or cannot interpret funnel/cohort analysis results.
- Lack of ownership or focus Shows a background of fragmented responsibilities without clear ownership of a growth metric or project lifecycle.
- Poor cross-functional collaboration Cannot provide examples of working with product, engineering, or design to implement experiments and follow through on results.
Use these as objective causes for filtering candidates quickly and fairly.

| Collaboration & Communication | 1–5 | Ability to work cross-functionally, present findings, and drive alignment |
| Cultural Fit & Ownership | 1–5 | Motivation for role, ownership examples, and alignment with company values |
Score each dimension 1–5 and capture evidence-based notes for calibration.
Closing & Selling The Role
To convert top candidates, highlight what matters to growth marketers: autonomy, measurable KPIs, resources, and career upside.
- Emphasize Ownership & Impact Sell the role as owning a key funnel metric with clear authority to run experiments and shape product decisions.
- Share Success Stories & Data Show recent growth wins, budgets, or examples of successful experiments to demonstrate seriousness and runway.
- Outline Tools & Support Describe analytics stack, creative resources, and engineering support available to execute experiments quickly.
- Career Path & Learning Explain progression (senior growth, head of growth, product leadership) and opportunities for cross-functional exposure.
- Competitive Compensation Framing Be clear about base, bonus, equity and how performance will influence future compensation and responsibilities.
Be transparent about expectations, growth runway, and how success will be measured.
Red Flags
Watch for signals that a candidate may struggle in a growth environment.
- Defensive About Failures Avoids discussing failed experiments or blames others instead of extracting learnings.
- Overly Specialist With No Breadth Excellent in one channel but no understanding of funnels, product, or lifecycle work when the role requires cross-functional competence.
- Data Illiteracy Cannot read basic funnels, confuse correlation with causation, or lacks familiarity with core analytics tools.
- Slow Execution Mindset Prefers long planning cycles and perfection over rapid, iterative testing and shipping.
- Poor Communication Struggles to present findings, justify decisions, or tailor messages to stakeholders.
Onboarding Recommendations
A structured first 90 days ensures early wins, alignment, and sets a cadence for growth experiments.
- Week 1–2: Ramp & Instrumentation Review Meet cross-functional partners, audit current analytics and event instrumentation, and review the backlog of previous experiments and outcomes.
- Week 3–4: Quick Wins & Hypothesis Backlog Ship 1–2 low-cost experiments (copy, targeting, onboarding tweak). Build a prioritized hypothesis backlog using an ICE/RICE framework.
- Day 30–60: Medium-Impact Experiments Execute medium-sized experiments requiring product/engineer support. Establish repeatable experiment templates and tracking dashboards.
- Day 60–90: Scale & Process Scale winning experiments, document learnings, and formalize cadences for experiment review, creative production, and reporting. Set KPI targets for the next quarter.
- Ongoing: Team & Tooling Optimization Identify tooling gaps, hiring needs, and process improvements that will compound growth outcomes.
Continue weekly check-ins and a 30/60/90 review cadence to keep momentum and adjust the plan.
