You know Google Ads.
You've managed campaigns, worked with budgets, analysed performance, and spent more time looking at search terms than you'd probably like to admit.
Now you need to explain all of that in a PPC job interview.
That's where even experienced candidates can struggle.
A good PPC interview isn't simply a test of how many Google Ads features you can name. Employers want to understand how you think, how you approach problems, whether you understand the commercial purpose behind campaigns, and what you actually contributed to the accounts you've worked on.
They're not only asking:
"Do you know PPC?"
They're trying to answer:
"Would we trust this person to manage our clients, campaigns, or advertising budget?"
Here's how to prepare.
Know the Role You're Interviewing For
Start with the job description.
Not five minutes before the interview.
Properly read it.
Look at the platforms, responsibilities, clients, budgets, and skills mentioned.
Does the role focus on:
- Google Ads?
- Microsoft Advertising?
- Search?
- Shopping?
- Performance Max?
- Lead generation?
- Ecommerce?
- GA4 and tracking?
- Client management?
- Strategy?
- Team management?
Then compare those requirements with your own experience.
Identify where you have strong examples and where you might need to prepare for questions.
If Shopping appears five times in the job description, there's a good chance somebody is going to ask about Shopping.
Research the Company
You don't need to memorise the company's entire history.
But you should understand where you're interviewing.
If it's an agency, look at:
- The types of clients they work with
- Industries they specialise in
- Other marketing services they provide
- Their size
- Their positioning
- Their case studies
If it's an in-house role, understand:
- What the company sells
- Who its customers are
- How people might search for its products or services
- Its competitors
- Its customer journey
This preparation helps you ask better questions and gives you useful context if you're presented with a hypothetical PPC scenario.
Be Ready to Explain What You Actually Manage
One of the first things an interviewer may want to understand is the scale and complexity of your current experience.
Be prepared to talk about:
- Number of accounts
- Monthly budgets
- Campaign types
- Industries
- Markets
- Platforms
- KPIs
- Your level of responsibility
You don't need to reveal confidential information.
But there is a significant difference between assisting with a £2,000-per-month account and independently managing £100,000 in monthly spend.
Neither experience is automatically better or worse for every role.
Employers simply need to understand what you've actually done.
Prepare Your Best Campaign Examples
Don't rely on remembering good examples while you're sitting in the interview.
Prepare them beforehand.
Choose three or four campaigns or situations that demonstrate different skills.
For example:
- A campaign you improved
- A difficult problem you solved
- A successful test
- A campaign that didn't work initially
- An account you scaled
- A tracking issue you identified
For each one, be ready to explain:
What was happening?
What was the objective?
What did you identify?
What did you personally do?
Why did you make that decision?
What happened afterwards?
Specific examples are much more convincing than general statements.
Know Your Numbers
"I improved performance."
How?
"Quite significantly."
By how much?
This is where interviews can become uncomfortable if you haven't prepared.
Try to know the key numbers behind your strongest examples.
You might say:
"CPA had increased to approximately £65. After restructuring the campaigns and tightening our search-term strategy, we reduced it to around £48 over the following two months while maintaining conversion volume."
That gives the interviewer something concrete.
Useful numbers might include:
- Budget
- CPA
- ROAS
- Revenue
- Conversion volume
- Conversion rate
- CPC
- Percentage improvements
You don't need to memorise every metric from every account.
Know the numbers behind the examples you're planning to discuss.
Expect to Be Asked Why
A PPC interview shouldn't only test what you did.
It should test why you did it.
Imagine you say:
"I changed the bidding strategy."
A good interviewer might ask:
Why?
Then:
What data supported that decision?
Then:
What happened afterwards?
Then:
What would you have done if performance hadn't improved?
This is where employers start seeing how you actually think.
Don't prepare a list of impressive-sounding actions.
Prepare the reasoning behind them.
Understand the Fundamentals
Automation has changed PPC significantly.
But fundamentals still matter.
You should be comfortable discussing areas such as:
- Search intent
- Keyword strategy
- Match types
- Negative keywords
- Quality Score
- Ad Rank
- Bidding
- Budgets
- Conversion tracking
- Search terms
- Landing pages
- Attribution
- Auction competition
You don't need to recite textbook definitions.
In fact, practical explanations are usually stronger.
If somebody asks about match types, for example, they probably aren't testing whether you've memorised Google's definition.
They may want to understand how you'd actually use them.
Be Ready to Talk About Performance Max
If you're interviewing for a Google Ads role, there's a reasonable chance Performance Max will come up.
Be prepared to discuss:
- When you might use it
- How you evaluate performance
- Asset groups
- Audience signals
- Search themes
- Product feeds
- Brand controls
- Creative assets
- Conversion goals
Avoid treating Performance Max as either magic or something that should never be used.
Employers generally want to see that you understand how to work with automation while still applying human judgement.
Understand Smart Bidding
The same applies to bidding.
You may be asked when you would consider strategies such as:
- Maximise Conversions
- Target CPA
- Maximise Conversion Value
- Target ROAS
The strongest answer isn't simply:
"I use Target CPA for lead generation."
Explain what you'd consider.
Do you have reliable conversion tracking?
Is there enough conversion volume?
Are all conversions equally valuable?
Is the target realistic?
How much historical data exists?
Good PPC decisions depend on context.
Your interview answers should demonstrate that.
Prepare for Scenario Questions
Some of the best PPC interview questions don't have one correct answer.
For example:
"CPA has increased by 40% this month. What would you check?"
Don't immediately answer:
"I'd lower the bids."
Start investigating.
You might look at:
- Whether tracking is working
- When performance changed
- CPC trends
- Conversion rates
- Search-term quality
- Budget limitations
- Auction insights
- Device performance
- Location performance
- Landing-page changes
- Seasonality
- Competitor activity
The interviewer is often more interested in your diagnostic process than whether you guess the correct cause immediately.
Prepare for a PPC Task
Some employers include a practical task as part of the hiring process.
You might be given:
- An account audit
- Campaign data
- A strategy brief
- Keyword research
- A reporting exercise
- A hypothetical budget
- A presentation
Don't try to identify 50 tiny optimisations to prove how thorough you are.
Prioritise.
If tracking is broken, that's probably more important than changing a headline.
If one campaign accounts for 70% of spend and is performing poorly, that may deserve more attention than a campaign spending £10 per day.
Show that you understand impact.
Don't Just Point Out Problems in an Audit
If you're asked to audit an account, identifying problems is only half the task.
For every major issue, try to explain:
What's happening?
Why does it matter?
What would you change?
What impact would you expect?
For example:
"A significant proportion of non-brand spend is going towards low-intent search terms. I'd review the search-term report, introduce additional negatives, and assess whether the current match-type strategy is giving Google too much flexibility given the available conversion data."
That's considerably stronger than:
"Needs more negative keywords."
Be Comfortable Talking About Tracking
You don't need to be a Google Tag Manager developer.
But PPC professionals should understand where their conversion data comes from.
Prepare to discuss:
- GA4
- Google Tag Manager
- Google Ads conversion tracking
- Enhanced conversions
- Consent Mode
- UTMs
- Attribution
- Offline conversion imports
- CRM data
A particularly useful question to prepare for is:
"What would you do if Google Ads suddenly reported 50% fewer conversions?"
The answer shouldn't automatically be:
"Optimise the campaigns."
First, determine whether the decline is real.
Show Commercial Awareness
This is particularly important for more senior positions.
Imagine two campaigns:
Campaign A: £30 CPA
Campaign B: £55 CPA
Which one is better?
You don't know yet.
Perhaps Campaign B generates customers worth five times as much.
Perhaps Campaign A's leads rarely convert into sales.
Perhaps Campaign B sells a product with significantly better margins.
Employers want PPC professionals who understand that platform metrics aren't the business objective.
Be prepared to talk about:
- Profitability
- Lead quality
- Revenue
- Margins
- Customer lifetime value
- Sales conversion rates
- Business growth
Show That You Can Communicate
Technical ability matters.
But many PPC roles involve communicating with people who aren't PPC specialists.
You may need to explain performance to:
- Clients
- Marketing Managers
- Directors
- Sales teams
- Finance teams
- Junior colleagues
Try not to answer every interview question with layers of Google Ads terminology.
Being able to simplify something complicated without making it inaccurate is a valuable skill.
Prepare for Client Questions
If you're applying to an agency, expect questions about clients.
For example:
"How would you handle a client who wants to double conversions without increasing budget?"
or:
"What would you do if a client disagreed with your recommendation?"
The interviewer is looking for more than technical knowledge.
They want to see whether you can manage expectations, communicate trade-offs, and maintain a professional relationship.
A strong PPC Manager needs people skills as well as platform skills.
Talk About Failed Tests
You don't need to pretend everything you've ever done worked.
In fact, saying every campaign was successful can make your experience sound less credible.
Be prepared to discuss something that didn't work.
Explain:
- What you expected
- What you tested
- What happened
- What the data showed
- What you changed afterwards
- What you learned
Paid media involves experimentation.
Employers want people who can learn from unsuccessful tests rather than hide them.
Don't Blame the Algorithm for Everything
Sometimes Google does something frustrating.
Anyone who has worked in PPC knows that.
But repeatedly blaming Google, Performance Max, Smart Bidding, or "the algorithm" for poor results isn't particularly convincing in an interview.
Explain what you can control.
Perhaps you:
- Improved conversion signals
- Changed campaign structure
- Adjusted targets
- Improved creative assets
- Fixed tracking
- Changed budget allocation
- Refined the product feed
Great PPC professionals understand the limitations of automation without using those limitations as an excuse for every performance problem.
Be Honest About What You Don't Know
You will eventually get a question you can't answer.
That's fine.
Don't invent an answer.
A better response might be:
"I haven't personally implemented that before, but I've worked with our analytics team on similar tracking setups. My first step would be to confirm how the conversion is currently being recorded and then work through the implementation requirements."
That shows honesty and problem-solving.
Nobody knows everything in paid media.
Knowing how to find an answer matters too.
Prepare Questions for the Employer
An interview works both ways.
You need to understand whether the role is actually right for you.
Useful questions might include:
- What types of accounts would I manage?
- What is the typical monthly spend?
- How is the PPC team structured?
- How much client contact would I have?
- What would success look like in the first six months?
- How are accounts allocated?
- What reporting tools do you use?
- How much responsibility would I have for strategy?
- What progression opportunities exist?
These questions also demonstrate that you're thinking seriously about the role rather than simply trying to get any PPC job available.
If You're Applying for Your First PPC Role
You won't have years of campaign examples.
Employers know that.
Focus instead on demonstrating:
- Understanding of PPC fundamentals
- Curiosity
- Analytical ability
- Commercial awareness
- Relevant certifications
- Personal projects
- Practice account audits
- Transferable skills
- Willingness to learn
If you've built a practice campaign strategy, include it.
If you've analysed a company's search advertising and identified opportunities, talk about it.
You don't need to pretend to have experience you don't have.
Show that you've made an effort to develop practical knowledge.
If You're Applying for a PPC Manager Role
The expectations change.
Employers are likely to care less about whether you know how to add a negative keyword.
They'll expect that already.
Instead, prepare examples demonstrating:
- Account ownership
- Strategy
- Budget management
- Forecasting
- Client communication
- Commercial thinking
- Problem-solving
- Prioritisation
- Mentoring
- Leadership
The more senior the role, the more your interview should demonstrate judgement rather than simply execution.
What Employers Really Want to See
Different employers prioritise different skills.
But strong PPC candidates usually demonstrate a combination of:
Technical knowledge
You understand how paid search works.
Analytical ability
You can interpret performance rather than simply report it.
Problem-solving
You investigate before making random changes.
Commercial awareness
You understand that PPC exists to generate business results.
Communication
You can explain complicated ideas clearly.
Curiosity
You want to understand why things happen.
Ownership
You take responsibility for outcomes.
Adaptability
You can work with changing platforms, clients, and priorities.
Google Ads knowledge gets you into the conversation.
These skills can help get you hired.
The Bottom Line
Preparing for a PPC interview isn't about memorising every possible Google Ads question the night before.
It's about preparing evidence.
Know your campaigns.
Know your numbers.
Know why you made your decisions.
Prepare examples of successes, problems, tests, and lessons.
Understand the company.
Understand the role.
And be ready to demonstrate that you can think beyond the advertising platform.
Because ultimately, employers aren't hiring someone simply to operate Google Ads.
They're hiring someone they can trust with budgets, campaigns, clients, data, and business objectives.
Show them that person in the interview.
