Interview Questions / PPC Specialist
30+ PPC Specialist Interview Questions for Agency Hiring
A practical bank of questions, what to listen for, and red flags to help you hire an agency PPC specialist who can audit, launch, and scale paid media across Google, Meta, and beyond without burning client budget.
Why these questions?
Agency PPC specialists run more accounts at lower individual budgets than their in-house counterparts, switch verticals every meeting, and have to translate paid performance into a story clients can act on. The questions below test for platform fluency, commercial literacy, and the discipline to maintain hygiene across a portfolio without breaking accounts. Use the bank as a library and pick 8 to 12 questions that fit the seniority and channel mix you're hiring for.
General & background (5)
Walk me through your career and how you ended up running paid media at an agency.

- Inflates spend by counting team-level totals as their own
- Cannot describe the account structure of any past client

Agency-specific scenarios (6)

Work-sample evaluation
Strong PPC candidates can walk you through real artifacts (with client names redacted):
- A redacted Google Ads or Meta Ads account screenshot.
- An audit document delivered to a client or prospect.
- A creative testing matrix and the resulting performance lift.
- A monthly performance report or Looker Studio dashboard.
- A short narrative of one account from kickoff to a measurable outcome.
Refusal to share anything at all (even disguised) is itself a signal.
Frequently asked questions
How long should a PPC specialist interview process be?
Most agencies run three to four stages over two to three weeks: a recruiter screen, a hiring manager interview, a live account audit or case study, and a panel with strategy and analytics leads. Anything longer than four weeks tends to lose strong candidates.
Should PPC candidates complete a take-home account audit?
A short audit (two to three hours) on a redacted real account or a public case study is highly predictive. Avoid multi-day audits that ask for free strategy work on a live prospect account.
What is the biggest predictor of success in an agency PPC specialist?
A combination of platform fluency and commercial curiosity. Candidates who instinctively ask about LTV, gross margin, and the funnel beyond the click tend to outperform those who optimize purely to in-platform metrics.
Should we hire generalists or channel specialists?
For agencies under 25 people, generalists who can run two or three channels well are usually a better hire than deep specialists. Above that scale, dedicated Google Ads, Meta Ads, and LinkedIn specialists become viable.
How important are platform certifications?
They are a baseline signal, not a differentiator. Treat them as a credibility check rather than evidence of skill, and weigh hands-on portfolio examples far more heavily.
