PPC Interview Questions: How to Hire for Profitable Growth

Hiring someone to manage your paid advertising means trusting them with a significant part of your growth budget.

For a scaling DTC or consumer brand, that person’s decisions can influence customer acquisition costs, cash flow, product demand and profitability.

The interview needs to explore how they make those decisions. Platform knowledge matters, but so does understanding what the business needs to achieve, which customers are worth acquiring and whether the operation can support the demand being generated.

Whether you’re hiring a PPC Executive, PPC Analyst or PPC Manager, these interview questions will help you assess technical skills, commercial judgement and the ability to work across your business.

Before the interview: define what the hire needs to deliver

A useful interview starts with a clear brief.

Do you need someone to improve an existing Google Ads account, build paid acquisition from scratch or lead a broader performance marketing strategy?

Be specific about the role’s scope. PPC commonly covers paid search and Shopping, while some employers use it more broadly to include paid social. Candidates should understand which channels they will own, what support they will have and how success will be measured.

Before meeting candidates, agree:

• The growth objective: New customer acquisition, profitable revenue, subscription growth or expansion into a new market.

• The responsibilities: Campaign execution, strategy, analysis, agency management or team leadership.

• The resources: Budget, creative support, analytics, product feeds and website development.

• The business constraints: Product margins, stock availability, fulfilment capacity and cash flow.

  
  

This gives you a consistent basis for comparing candidates and makes it easier to distinguish relevant experience from an impressive presentation.

PPC interview questions to assess commercial understanding

1. “Talk us through a campaign that delivered a meaningful business result.”

Ask the candidate to explain the objective, starting position, budget, decisions and outcome.

Then explore their individual contribution. What did they own? What support did they receive? What changed because of their work?

Listen for: Clear evidence, an understanding of the numbers and an honest explanation of what worked.

A revenue increase becomes more useful evidence when the candidate can explain the acquisition cost, customer mix and effect on profitability.

2. “How would you decide whether a campaign is profitable?”

Return on ad spend, or ROAS, measures attributed revenue against advertising spend. It doesn’t tell you everything about the economics of an order.

A commercially aware candidate should want to understand product margins, discounts, returns and fulfilment costs. For subscription brands, they should also consider retention, repeat purchases and the time needed to recover acquisition costs.

Listen for: A willingness to question the target and understand how the business makes money.

3. “Reported ROAS is improving, but new customer growth is slowing. What would you investigate?”

This question tests whether the candidate can look beyond a platform dashboard.

They might explore changes in branded search, existing customer purchases, attribution, channel overlap or the balance between acquiring customers and capturing existing demand.

Listen for: A structured investigation and an understanding that attributed conversions don’t automatically prove additional growth.

PPC manager interview questions: strategy, automation and leadership

4. “How do you decide what to automate and where to intervene?”

AI and automation are part of modern paid media management. Google’s Performance Max, for example, uses AI across bidding, audiences and creative, with conversion goals and values helping guide optimisation.

Ask how the candidate checks the inputs, evaluates the outputs and decides when a change is justified.

Listen for: Clear objectives, reliable measurement, relevant creative and a considered approach to testing. They should be able to explain where human judgement adds value.

5. “What would your first 90 days in this role look like?”

A strong answer should start with understanding the business, customers, account history and measurement setup.

From there, the candidate should explain how they would prioritise improvements, agree targets and build a testing plan.

Listen for: Sensible sequencing, realistic expectations and a clear connection between account activity and business priorities.

6. “Tell us about a time you challenged a growth target.”

Founders and leadership teams need people who can assess ambitious plans and explain what achieving them would require.

Explore how the candidate handled a target that conflicted with budget, margins, available data or operational capacity.

Listen for: Evidence, constructive challenge and practical alternatives. Strong candidates should be comfortable explaining trade-offs and taking responsibility for their recommendations.

For management roles, also ask how they developed colleagues, delegated decisions and handled underperformance.

PPC analyst interview questions: measurement and decision-making

7. “Google Ads, analytics and ecommerce reporting show different revenue figures. How would you investigate?”

Ask the candidate to describe their process before suggesting a cause.

Relevant checks might include attribution windows, conversion definitions, duplicate events, refunds, time zones and tracking changes.

Listen for: A methodical approach and the ability to explain uncertainty clearly. The goal is to establish which information supports the decision you need to make.

8. “How would you assess whether advertising generated additional sales?”

This introduces incrementality: whether sales happened because of advertising, beyond what would have happened anyway.

Depending on the business, budget and available data, a candidate might discuss controlled experiments, geographic tests or platform lift studies.

Listen for: An understanding of test design, practical limitations and the difference between measuring an outcome and claiming credit for it.

9. “What would you recommend from this dataset?”

Give candidates a short, anonymised example with enough context to make a useful judgement.

Include spend, revenue, new customers, product margins and stock availability. Ask what they would investigate, what action they would recommend and what information is missing.

Listen for: Prioritisation and a clear recommendation. Effective analysis should help the team decide what to do next.

PPC executive interview questions: execution and collaboration

10. “Performance drops unexpectedly. What do you check first?”

A capable PPC Executive should be able to work through possible causes without making several changes at once.

Their checks might cover tracking, website functionality, budgets, product availability, feed issues and recent account changes.

Listen for: A logical process, appropriate escalation and an understanding of which issues need immediate action.

11. “How have you worked with creative, ecommerce or lifecycle teams to improve performance?”

Paid media results depend on the wider customer journey.

Ask for an example of how the candidate used campaign insights to improve an advert, landing page, product page or follow-up journey.

Listen for: Clear briefs, useful feedback and shared ownership of the outcome.

Assess how the candidate works across the business

For consumer brands, paid acquisition needs to connect with Sales & Commercial and Operations & Supply Chain.

You don’t need a PPC specialist to own these functions. You do need them to recognise when campaign decisions affect other teams.

Two useful scenarios are:

“The commercial team is planning a major retail launch. How would you contribute?”

Look for questions about launch objectives, retailer availability, timing, budget and measurement. A thoughtful candidate should recognise that ecommerce revenue alone may not capture the full objective.

“Your best-performing product has three weeks of stock remaining, and the next delivery is delayed. What would you do?”

Look for collaboration with operations, an assessment of alternative products and clear communication about the effect on spend and revenue forecasts.

These questions reveal whether a candidate can connect marketing activity with what the business can sell and deliver.

Use a consistent interview scorecard

Assess every candidate against the same core criteria:

• Technical capability: Can they manage the channels and tools required?

• Commercial judgement: Do they understand customers, margins and growth economics?

• Analytical thinking: Can they investigate performance and recommend action?

• Collaboration: Can they work effectively across functions?

• Leadership: Where relevant, can they set direction and develop others?

If you include a practical exercise, keep it proportionate to the role and use anonymised or fictional information. A short discussion can reveal how someone thinks without requiring a lengthy unpaid project.
