Job Description Do's and Don'ts
Write a clear job description that attracts senior-level digital marketers by focusing on impact, autonomy, and tools.
| Do | Don't |
|---|---|
| Specify primary channels, KPIs, and ownership (e.g., paid search, 40% of time; CRO, owner of A/B testing). | Use ambiguous phrases like "digital marketing experience" without indicating channels, metrics, or level of responsibility. |
| List the tech stack and tools the role will use and what access will be granted (e.g., GA4, GTM, HubSpot). | Demand unrealistic breadth without stating which areas are highest priority or offering support/resources. |
| Highlight impact and career growth: projects they will own and how success is measured. | Overemphasize admin tasks or make the role sound like a generalist assistant rather than a senior contributor. |
Avoid vague language and unrealistic expectations that deter strong candidates.
Sourcing Strategy
Target places where senior digital marketers congregate and showcase the role with clear impact and metrics.
- LinkedIn target outreach Use headline and experience filters for titles like Senior Digital Marketing Specialist, Performance Marketing Manager, or Paid Media Lead; personalize outreach with a recent campaign reference or KPI challenge.
- Referrals from current marketing and analytics teams Ask current team members for introductions to peers they've worked with; referrals often yield better cultural fit and clearer performance history.
- Niche job boards and communities Post to marketing-specific boards (GrowthHackers, Inbound.org alternatives), Slack communities, and forums where marketers share case studies.
- Talent bench via agencies and contractors Screen high-performing contractors or agency leads who may be open to full-time roles, especially for immediate execution needs.
- Content-driven sourcing Identify authors of high-quality marketing case studies, blog posts, or LinkedIn threads that demonstrate analytical rigor and experimentation.
Prioritize passive sourcing and referrals for senior hires—they often respond best to a compelling mission and clear growth path.
Screening Process
A structured process reduces bias and identifies candidates who demonstrate both strategy and execution skills.
- Resume Screen Look for channel ownership, measurable outcomes (ROAS, CPA, conversion rate improvements), and tenure on key projects.
- Recruiter Phone Screen (20–30 min) Confirm role fit, compensation expectations, notice period, and ask for a quick campaign example with metrics.
- Hiring Manager Technical Screen (30–45 min) Discuss recent campaigns, optimization frameworks, attribution understanding, and expectations for the role; probe on tools and technical tagging knowledge.
- Practical Skills Assessment Short take-home task or live case (e.g., audit a campaign, recommend optimizations, or sketch an A/B test plan) to verify hands-on skills.
- Cross-functional Interview Interview with analytics/product/creative partners to evaluate collaboration style and ability to integrate with existing workflows.
- Final Leadership Interview & Compensation Discussion Confirm strategic alignment, career aspirations, and negotiate offer with clarity on role expectations and success metrics.
- Reference Checks Validate campaign outcomes, work ethic, stakeholder management, and reliability.
Include a practical assessment early enough to validate hands-on capability before scheduling many interviews.
Top Interview Questions
Q: Describe a high-impact campaign you managed from strategy to results. What was your role and the outcome?
A: Look for a clear problem statement, the candidate's specific responsibilities, the tactics used, metrics tracked (e.g., CPA, ROAS, LTV), and a concise result with numbers. Strong answers include how learnings were scaled or rolled into other channels.
Q: How do you decide between investing in paid acquisition versus retention/CRM?
A: Good responses reference unit economics like CAC and LTV, marginal return on ad spend, cohort analysis, and experiments to quantify retention impact. Expect a framework that balances short-term growth and long-term value.
Q: Walk me through how you set up tracking and attribution for a new campaign.
A: Candidates should mention UTMs, goals/events in GA4, pixels and server-side tagging where applicable, validating events, and a plan for multi-touch attribution or rules used for reporting.
Q: Give an example of an A/B test you ran. How did you design it and interpret the results?
A: Assess experimental design (hypothesis, sample size, statistical significance), guardrails against bias, and how results informed rollout or next steps. Strong candidates discuss unexpected results and follow-up tests.
Q: Which marketing tools and platforms have you used, and which do you prefer for measurement?
A: Expect names of platforms (e.g., GA4, Looker/BigQuery, GTM, Meta Ads, Google Ads, HubSpot/Klaviyo) with reasons for preferences—speed, attribution capabilities, integrations, or automation features.
Q: Describe a time you disagreed with product or engineering on tracking or prioritization. How did you resolve it?
A: Look for constructive conflict resolution: data-driven arguments, presenting tradeoffs, proposing compromises, and aligning on minimum instrumentation to move forward.
Top Rejection Reasons
Deciding rejection reasons ahead of interviews helps you screen more consistently and avoid sunk-cost decisions.
- No measurable results Candidate cannot provide concrete metrics or outcomes from past campaigns (ROAS, CPA, conversion lift), only vague statements.
- Weak analytics skills Unable to interpret basic funnel metrics, set up conversion tracking, or explain an experiment's statistical significance.
- Limited hands-on experience with primary channels Claims seniority but lacks recent, practical experience in the channels you prioritize (e.g., paid search, paid social, or email automation).
- Poor collaboration or communication Struggles to explain cross-functional work, uses blaming language about prior teams, or cannot clearly articulate strategy to non-marketers.
- Unrealistic expectations Salary, role scope, or required resources are misaligned with what the company can offer and there is no willingness to negotiate on scope or timeline.
Use these reasons to calibrate expectations and communicate rejection feedback quickly and professionally.

Closing & Selling The Role
Senior candidates evaluate roles on impact, autonomy, and career trajectory. Sell the opportunity honestly and succinctly.

- Team & Culture Share examples of collaboration, cross-functional partnerships, and how marketing decisions are made to demonstrate an environment they can thrive in.
Be ready to negotiate and provide specifics about budget, headcount, and the first projects they'll own.
Red Flags
Watch for these signs during interviews and take-home assessments; they often predict future performance issues.
- Cannot cite concrete metrics Avoid candidates who talk in absolutes without numbers or context for success.
- Tool-only focus If a candidate emphasizes only tools rather than strategy or outcomes, they may lack higher-level judgment.
- Vague answers about failures Senior hires should be able to analyze failed experiments and explain lessons learned; vague responses indicate lack of reflection.
- Blame-oriented storytelling Consistent negative framing of past teams or leaders suggests poor collaboration or accountability.
- Resistance to hands-on work A senior specialist must be willing to execute; reluctance to engage in campaign setup, testing, or analysis is concerning.
Onboarding Recommendations
A structured onboarding accelerates impact. Provide access, context, and a clear 30/60/90 plan.
- Preboarding (Before Day 1) Grant access to analytics, ad accounts, CRM, and relevant dashboards; share product briefs, recent performance reports, and org chart.
- Week 1: Orientation & Immersion Introduce team and cross-functional partners, review product and customer personas, and walk through current campaigns and KPIs.
- Week 2–4: Audit & Quick Wins Have the new hire run a channel and tracking audit, identify 2–3 quick optimization opportunities, and own a small experiment to deliver an early win.
- 30/60/90 Plan Agree on measurable objectives for the first 30/60/90 days with clear success metrics, reporting cadence, and expected deliverables.
- Set Up Communication & Reporting Establish a regular reporting template, meeting rhythm with stakeholders, and a single source of truth for campaign performance.
- Ongoing Development Provide training resources, conference budget, and mentorship; schedule a 1:1 with the manager weekly for the first three months.
Set measurable goals and early wins to build momentum and demonstrate value.
