Most bad hires look great on paper.
They’ve got the certifications. They’ve run campaigns. They know what ROAS means.
Then you give them access to your ad account and six weeks later you’ve burned through budget with nothing to show for it.
The problem usually isn’t dishonesty. It’s that most interview processes for PPC roles are just bad at surfacing real skill.
Here’s how to fix that.

Get StartedWhy Most PPC Interview Questions Fail to Reveal Real Skill
The standard approach goes something like this: ask about their background, get a few Google Ads buzzwords back, look at their portfolio, make a gut call.
But PPC is one of those skills where knowing the vocabulary tells you almost nothing. Someone can explain Quality Score perfectly and still be terrible at managing real budgets under real pressure.
The questions that actually reveal skill are the ones that force candidates to show how they think, not what they know.
Skip “tell me about yourself.” You want diagnostic questions, organized by what you’re actually trying to find out.
Questions About PPC Campaign Strategy and Structure
These questions test whether someone builds campaigns around business goals or around platform mechanics.
“Walk me through how you’d structure a campaign from scratch for a business you’ve never worked with before.”
Listen for how they handle ambiguity. Do they ask about goals and budget before talking ad groups? Or do they jump straight into keyword research?
Good specialists know that structure follows strategy. They’ll ask what you’re trying to achieve before they touch anything in the platform. If someone starts with keywords before asking what you’re selling or who you’re selling to, that’s a flag.
“How do you decide between broad match, phrase match, and exact match for a new campaign?”
The wrong answer is a blanket rule. The right answer depends on budget, how much data you have, and how well you understand the search landscape. A specialist who says “I always start with exact match” hasn’t thought hard enough about when broad match with strong negatives is actually faster to learn from.
“What does your campaign structure look like for a product with multiple audience segments?”
This surfaces whether they think in terms of ad relevance and landing page alignment, or just traffic volume. Segmenting by audience isn’t just about targeting, it’s about message match. A strong candidate talks about both.
Questions About PPC Performance and Optimization
These questions reveal how someone diagnoses and fixes problems. Anyone can manage a campaign that’s working. You want to know what they do when it isn’t.
“Tell me about a campaign where you had strong click-through rates but weak conversions. What did you do?”
The surface answer: “I ran A/B tests and improved the landing page.” Fine, but vague.
A real answer shows diagnosis. They’ll tell you how they figured out where the breakdown was: traffic quality, landing page mismatch, offer friction, or something else entirely. They’ll tell you what they tested first and why. They’ll give you numbers.
“A campaign’s CPC has been climbing for three weeks with no obvious changes on your end. Walk me through how you’d investigate.”
This is a better CPC question than “how do you reduce CPC?” because it’s specific. Costs can climb for a dozen reasons: competitor activity, auction changes, seasonality, Quality Score decay, match type creep. Someone who immediately goes to bid cuts without auditing the full picture is optimizing for the metric instead of the outcome.
“What’s the first thing you look at when a campaign’s performance drops suddenly?”
Watch for structure in the answer. A good specialist has a diagnostic sequence: they check for account-level changes, then campaign-level, then external factors. Someone who says “I’d check the ads” and stops there hasn’t built a real troubleshooting process.
“Tell me about a campaign where you improved ROAS significantly. What changed, and what did you rule out before making that change?”
The second part of this question is the important one. Anyone can claim a ROAS win. Fewer people can tell you what they tested and eliminated before arriving at the fix. That’s the difference between someone who got lucky and someone who knows why something worked.
Questions About Budget Management and Bidding Strategy
“How do you approach budget allocation across multiple campaigns with different goals?”
This tests whether they understand that not all budget decisions are equal. Brand campaigns protect existing demand. Prospecting campaigns create new demand. Someone who allocates budget based on performance alone, without thinking about the role each campaign plays, will starve the campaigns that take longer to show results.
“You’re halfway through the month and you’ve spent 80% of the budget. What do you do?”
There’s no single right answer here, which is why it’s useful. Do they pause low performers? Reduce bids across the board? Ask you what the priority is? A candidate who immediately starts cutting without asking about your business situation is making decisions they shouldn’t be making alone.
“How do you handle a campaign where hitting the ROAS target would require cutting spend that’s driving volume for a long sales cycle?”
This is the kind of real tension that comes up in B2B and high-ticket products. A specialist who can’t navigate it will either blow the budget chasing leads that won’t close, or cut the campaigns that are actually feeding your pipeline.
Questions About Google Ads Knowledge and Tools
“How do you use auction insights, and when does it actually change what you do?”
A lot of people say they use auction insights. Fewer have a clear answer for when it meaningfully changes their strategy. The honest answer is that it’s directional data, not prescriptive. A specialist who treats it as gospel probably leans too hard on platform-reported data in general.
“What’s your process for building a negative keyword list for a new account?”
This is detail work that separates sloppy campaign managers from precise ones. A strong answer covers: starting with obvious irrelevant terms, running search term reports early and often, and building negatives at both campaign and ad group level depending on the match type structure. Someone who adds negatives reactively, only after wasted spend, is always going to be behind.
“What third-party tools do you use alongside Google Ads, and what specific problem does each one solve for you?”
This isn’t about listing tools. It’s about whether they can articulate why they use them. SEMrush for competitor gap analysis is a different use case than using it for keyword research. Someone who lists five tools but can’t explain the specific problem each one solves is probably using them superficially.
Questions That Reveal Accountability and Self-Awareness
These are the questions most interviewers skip. They shouldn’t.
“Tell me about a campaign you managed that went badly. What happened, and what did you take from it?”
Most candidates prep their wins. Almost nobody preps their losses. If they can’t answer this, one of two things is true: they haven’t done enough real PPC work to fail yet, or they’re not self-aware enough to have learned from it. Neither is good.
“Have you ever pushed back on a client or manager about a campaign decision? What happened?”
You want someone who can manage up, not just manage down. A PPC specialist who executes every instruction without flagging problems isn’t protecting your budget. They’re just processing tasks.
“How do you stay current with platform changes? Give me a recent example of something that changed how you work.”
Google Ads changes constantly. Broad match behavior, Performance Max, smart bidding defaults, all of it shifts. A specialist who can’t point to a specific recent change that affected their approach is probably running the same playbook they learned two years ago.
How to Use a Trial Task to Test a PPC Specialist Before Hiring
No question reveals more than a live test.
Give them a an account export to audit, a budget forecast scenario, or a campaign structure for your actual business.
Give them 20-30 minutes and ask them to come back with what’s wrong, what they’d fix first, and what they’d leave alone.
That last part trips up a lot of people. Not everything needs to be fixed. Over-optimizing a campaign that’s quietly working is a real mistake.
If they hand you a five-point plan with no caveats and no questions, be careful.
What to Really Look for When Hiring a Remote PPC Specialist
You’re not hiring a Google Ads operator. You’re hiring someone who can make decisions with your money when you’re not watching.
Business judgment matters as much as platform fluency. Someone who asks about your margins before setting a target CPA, who flags when a campaign goal doesn’t match the offer, who knows when not to spend, that’s the hire that compounds.
The interview is just how you find them.
US and UK companies hiring Filipino PPC specialists remotely typically see 70-90% in labor cost savings compared to local hires, with solid mid-level talent at around $1,000-1,100 per month.
That’s not a reason to rush the vetting. It’s a reason to vet well and commit to the right person.
The savings only matter if the hire works.
