Two candidates sit in front of you, and both portfolios are excellent. The work is polished, the campaigns look sharp, and the numbers on the slides are impressive. On the strength of the folders alone, you could not separate them. And that is the problem with hiring in marketing and media: the portfolio is the easy part. It gets a candidate through the door, but it answers almost none of the questions that actually decide whether they will deliver for you.
Marketing is unusual among creative fields because it is measured. A campaign is not just meant to look good; it is meant to move a number: revenue, pipeline, sign-ups, retention. That measurability should make hiring easier, and instead it makes it harder, because a portfolio can show you beautiful work, impressive-looking results, or both, without telling you whether the candidate understood the difference. The questions that matter are the ones the folder cannot answer. Did this work actually move the business, or just look like it did? Is this person creative or commercial, and which do you need? And behind the tidy metrics, do they understand what really happened?
Here is how to find out.
The first thing to separate is how something looked from what it did. A portfolio is built to be admired, so it naturally foregrounds the polished artefact: the launch film, the rebrand, the campaign that won the pitch. What it tends to omit is whether any of it worked in the terms the business actually cared about.
For every piece a candidate is proud of, move the conversation from the output to the outcome. What was this meant to achieve, and did it? What did the business look like before and after? A strong marketer is comfortable connecting their work to a commercial result and is honest about where the line is fuzzy. A weaker one keeps returning to how the work looked, how much engagement it got, or how the client felt about it, because that is the part they can speak to. Beautiful work that moved nothing is not a portfolio strength. It is a warning that this person may optimise for the wrong thing.
Marketing has quietly split into two disciplines that are almost different professions, and one of the most common hiring mistakes is failing to notice which one you are interviewing. Creative and brand marketers think in ideas, stories, and how a brand feels over time. Performance and growth marketers think in channels, data, testing, and cost per result. Both are real marketing. They attract different people, reward different instincts, and rarely live in equal measure in the same person.
A portfolio can disguise which one you are looking at, because a good deck presents creative work and performance results side by side as though one person drove both. Ask directly. Where does the candidate do their best thinking, in the idea or in the optimisation? Which part of a campaign energises them, and which part do they tolerate? You are not looking for a weakness; you are looking for a shape. The failure here is not hiring a specialist. It is hiring a brilliant brand thinker into a role that needed someone to bring down acquisition cost, or a sharp performance marketer into a role that needed someone to build a brand, and discovering the mismatch six months in.
Because marketing is measured, marketing candidates come armed with numbers. "Grew the channel by 300%," "tripled engagement," "cut cost per lead by half." These sound like evidence, and sometimes they are. Often they are the most misleading part of the whole conversation, because a number without its context tells you nothing, and marketing numbers are unusually easy to claim credit for.
Probe two things. First, attribution: how does the candidate know their work caused the result, rather than a budget increase, a seasonal lift, a pricing change, or a strong team around them? A marketer who understands attribution will talk honestly about what they can and cannot prove. One who does not will present correlation as if it were proof. Second, watch for vanity metrics. Impressions, followers, and engagement are easy to grow and often disconnected from anything commercial. Revenue, conversion, retention, and pipeline are harder and matter more. A candidate who instinctively reaches for the vanity metrics, or cannot translate their activity into a business outcome, may not understand the difference themselves. That gap is worth finding before you hire, not after.
A decade ago, a marketer was a relative generalist. Today, the field has fragmented into specialisms that share a job title and little else: brand, content, social, SEO, paid media, lifecycle and email, product marketing, growth, and marketing operations. Someone can be genuinely excellent in one of these lanes and close to a novice in the others, while their CV simply says "Marketing Manager."
This is where a vague brief does real damage. Before you assess anyone, be specific about the lane you are hiring for and the depth you need in it. Then check that the candidate's actual experience sits in that lane, rather than assuming a marketing title covers it. A content specialist and a paid-media specialist are not interchangeable, however similar their titles look. If you need someone to own performance advertising, a portfolio full of award-winning brand work is not reassurance; it is a signal that this person's centre of gravity is somewhere else. Matching the specialism to the need is half the assessment, and it is the half most easily skipped.
Marketing runs on tools, and the tools change constantly. There is a natural temptation to hire for fluency in the specific platforms you use, and some of that is reasonable. But knowing how to operate a tool is not the same as knowing what to do with it, and this distinction matters more in marketing than in almost any other function.
Someone can run a campaign on an ad platform without understanding why a campaign should be structured one way rather than another. Someone can produce content at speed, increasingly with the help of AI tools, without the judgment to know what is worth producing. Platform skills are learnable in weeks. Marketing judgment, the sense of what to do and why, takes years and does not transfer from a manual. So test for the thinking, not the button-pushing. Ask why a candidate made the choices they did, not just whether they can operate your stack. The marketer who understands the reasoning will adapt when the tools change, which in this field they always will. The one who only knows today's tools will need replacing when tomorrow's arrive.
Most recruiters can gather portfolios and arrange interviews. Fewer can tell a creative marketer from a performance marketer, read past a confident set of metrics to what actually happened, or place a candidate in the right lane of a fragmented field, because doing so requires understanding marketing itself. That is the real value a specialist brings: an assessment built around commercial substance and the right specialism, rather than the surface of a strong folder.
A recruiter who understands marketing will separate output from impact, identify whether a candidate is built for brand or for growth, interrogate the numbers properly, and match the specialism to the role you actually need filled. That is the same quality-over-volume approach that protects you from a costly mis-hire in any field, applied to a sector where an impressive first impression is especially easy to manufacture and especially easy to misread.
At Recruitment Legends, this is how we approach marketing and media hiring. We separate work that looked good from work that moved the business, identify whether a candidate is built for brand or for performance, interrogate the numbers properly, and match people to the specialism and environment they will actually work in, so you hire the marketer who delivers, not just the one with the best-looking folder.
