What I Got Wrong About Hiring Media Buyers

The first media buyer I hired looked great on paper.

Two years at a large agency. Managed significant ad spend. Could speak fluently about campaign structure, bidding strategies, and audience segmentation. Passed every technical screen. Three weeks into the role, it was clear something was wrong. Accounts were technically managed but not strategically driven. Client performance was flat. Every problem got escalated. Every judgment call required a meeting.

I hired a tactician when I needed a thinker.

That mistake — and the three or four iterations of it that followed before I understood what I was actually hiring for — cost real money in client churn, internal rework, and management time that should have been spent elsewhere. It also forced me to build a much clearer model of what the media buyer role genuinely requires at a performance agency that wants to grow.

Here's what I got wrong, and what I eventually got right.

The mistake: hiring for platform fluency instead of commercial judgment

The performance marketing industry has an over-indexing problem with platform certifications and technical knowledge as proxies for media buying ability.

Can they navigate Ads Manager fluently? Can they explain broad versus interest targeting? Can they set up a conversion campaign from scratch? Legitimate baseline requirements. They are not the skills that determine whether a media buyer will actually move client performance in a meaningful direction.

The skills that determine that are much harder to evaluate in a standard interview.

Does this person read data and form an independent hypothesis, or do they wait for direction before they act? When performance drops unexpectedly, do they diagnose the cause or reach for the most obvious lever? When a client pushes back on a recommendation, do they hold the position with evidence or capitulate?

I spent years interviewing for the wrong things because the right things are harder to screen for and require more deliberate interview design to surface.

What the role actually requires

The modern media buyer at a performance agency is not an ad technician. The platforms have automated enough of the execution layer that raw technical proficiency is table stakes, not a differentiator.

What the role actually requires is a specific combination of analytical thinking, creative instinct, commercial awareness, and client communication ability that most job descriptions don't come close to capturing.

Analytical thinking under ambiguity

Paid media data is noisy. Attribution is imperfect (more on that here). Results fluctuate for reasons that have nothing to do with campaign decisions. A strong media buyer can distinguish between signal and noise, knows when to act on a data point and when to let it breathe, and can construct a coherent narrative from a messy dataset.

The failure mode here is paralysis or, worse, false confidence. A media buyer who can't tolerate ambiguity will either over-optimize on noise or wait for certainty that never comes. Both produce poor results at scale.

Creative instinct and brief literacy

This is the insight that most changed how I hire.

Media buying and creative strategy are not separate functions. They inform each other continuously. A media buyer who cannot read creative performance data at a granular level — hook rate, hold rate, CTR by creative type, audience-to-creative alignment — is missing half the information they need to make good budget decisions.

A media buyer who cannot give the creative team useful feedback based on that data is creating a bottleneck in the feedback loop that slows the entire account's improvement rate.

I now look for media buyers who can articulate why they think a specific creative is underperforming and what they'd test next. Not as an academic exercise — as a practical brief direction they would give to a creative strategist. If they can't do that, they're only doing half the job.

Commercial awareness

A media buyer managing $200K/mo in ad spend is making decisions that directly affect client revenue, margin, and business outcomes. The best media buyers understand this and hold themselves accountable to business results, not just platform metrics.

They know their clients' contribution margin targets. They understand why a 2.8x ROAS at a 35%-margin business is a different situation than a 2.8x ROAS at a 55%-margin business. They think about scaling decisions in terms of what they do to the client's bottom line, not just what they do to the ROAS dashboard.

Hiring someone without this commercial awareness and then giving them budget authority is a structural risk most agencies underestimate.

Client communication as a core competency

This was the hardest lesson.

I consistently underweighted communication ability in hiring because I told myself client management was a separate function and media buyers just needed to focus on the work.

That model breaks down in practice. Clients interact with their media buyer regularly. When performance is strong, communication is easy. When performance drops — which it will — the media buyer's ability to explain what happened, what they're doing about it, and what the client should expect next is the difference between a retained account and a churn conversation.

A technically brilliant media buyer who cannot communicate clearly to a non-technical client is a liability at the agency level, even if their campaign results are strong.

The hiring process I should have built earlier

The interview process I use now is fundamentally different from the one I used in the first two years of building Impremis.

Stage 1: The data interpretation exercise

Before any interview, candidates receive a real anonymized account dataset. Not a clean example — a messy one with conflicting signals, one metric that looks strong and three that look concerning, and a recent performance drop without an obvious explanation.

They have 48 hours to review it and prepare a five-minute verbal walkthrough of what they see, what they think is happening, and what they would do next.

This exercise surfaces more about a candidate's analytical approach than any interview question I've ever used. The quality of the hypothesis matters less than the quality of the thinking. Can they construct a coherent narrative? Do they acknowledge uncertainty or overstate confidence? Do they connect the data to business implications or stay inside the platform metrics?

Stage 2: The creative feedback simulation

Candidates are shown three different ad creatives from the same brand and given basic performance benchmarks for each. They explain why they think each performed the way it did and what brief direction they'd give for the next test.

Not a creative strategy interview. An integration interview. I want to see whether the candidate can move fluidly between data analysis and creative direction, connecting the what of performance to the why of creative execution.

Candidates who can do this well are rare. When I find one, I hire them.

Stage 3: The client scenario role play

A senior team member plays a client who has received a bad monthly performance report. The candidate has to walk them through the results, explain what happened, and present a path forward.

Not about polish or presentation skills. About whether the candidate can stay calm under pressure, acknowledge difficult results without becoming defensive, and communicate a clear plan with appropriate confidence given the information available.

I've seen technically strong candidates completely fall apart in this scenario. I've also seen less technically impressive candidates handle it so well that it changed my assessment of their hire-worthiness significantly.

What strong media buyers have in common

After enough hiring cycles, patterns emerge. The media buyers who consistently produce strong results across multiple client accounts share a specific set of behaviors that are not platform-specific and not experience-level-specific.

| Characteristic | What it looks like in practice | How to screen for it | |---|---|---| | Proactive hypothesis formation | Brings a theory to every data review, doesn't wait for direction | Data interpretation exercise | | Creative + media integration | Can brief creative from performance data without being asked | Creative feedback simulation | | Intellectual honesty | Acknowledges when results are genuinely unclear instead of forcing an explanation | Observe response to ambiguous data | | Commercial orientation | References client business outcomes, not just platform metrics | Ask them to explain a scaling decision in business terms | | Structured communication | Can simplify complex performance situations for non-technical audiences | Client scenario role play | | Ownership mentality | Treats client accounts as their own responsibility, not a task queue | References to proactive actions taken without being asked |

The absence of any one of these can be worked around. The absence of two or more usually predicts a performance ceiling that training will not move.

The onboarding failure that compounds bad hires

Even when you hire well, onboarding failure is one of the most common reasons strong media buyers underperform in their first 90 days.

The standard agency onboarding model is: here are the tools, here are the clients, here are the logins. Good luck.

That model fails even talented hires because it doesn't transfer the institutional knowledge, client context, and performance standards a new media buyer needs to make good decisions on day one.

The onboarding process I now use has three structured components:

1. Client context brief for every account the new hire touches. Two pages covering the brand's business model, unit economics, historical performance patterns, what's been tested, what the client cares most about, and what has historically created friction in the relationship. A new media buyer who reads these briefs before touching a single campaign has a fundamentally different starting point than one who figures it out through trial and error.
2. 30-day shadow period on all client communications. The new hire drafts responses and recommendations. A senior team member reviews before anything goes to the client. This is not micromanagement — it's calibration. It establishes the communication standard before mistakes are made in front of clients.
3. Weekly performance review ritual for the first 90 days. The new hire presents their account analysis to a senior team member and defends their decisions. This accelerates judgment development faster than any other method I've found. Explaining your decisions out loud to someone who will push back forces the kind of rigorous thinking that independent work doesn't always demand.

The broader agency implication

The media buyer hiring problem is ultimately a reflection of how clearly the agency has defined what excellence looks like in the role.

Agencies that hire by résumé and platform experience will get tacticians. Agencies that hire by commercial judgment, creative integration, and communication ability will get operators.

The operator is worth two or three times as much to the agency at the business level, because they retain clients longer, scale accounts more confidently, and require significantly less senior management time to oversee.

The ROI of improving your media buyer hiring process is not an HR outcome. It's a revenue and margin outcome. It shows up in client retention rates, account growth velocity, and the amount of time leadership spends firefighting versus building.

Getting this right is one of the highest-leverage operational improvements a growth-stage performance agency can make.

FAQ

At what agency size does this hiring rigor really matter? At three media buyers and up. Below that, the founder is closer to every account and can compensate for hiring gaps. Above that, hiring quality compounds into account-level outcomes faster than any individual intervention can fix.

How long should the data-interpretation exercise take to score? 30 minutes. The quality of thinking is usually visible inside the first three minutes of the verbal walkthrough.

Can junior candidates pass these stages? The strongest ones can. Tactical experience is a fine starting point but not a substitute for the four core skills. I've hired junior candidates with one year of experience who outperformed senior candidates with five.

Should I run all three stages for every hire? Yes. Skipping the role play is the most common shortcut and the one that bites the most.

Closing

The candidate with the impressive agency pedigree and the Meta certification may still be the right hire. But those credentials should be the starting point of your evaluation, not the conclusion.

The job requires judgment, integration, commercial awareness, and communication. Build your process to screen for those things directly.

You'll reject some candidates you would have previously hired. You'll hire some candidates you would have previously overlooked. Over time, your team will look different, perform differently, and retain clients at a rate that reflects the difference.

That's the hiring outcome worth building toward.
