How to Evaluate Content Writing Skills When Hiring

To evaluate content writing skills, map the role to the exact skills it needs, then test each one with real evidence: a scored writing assessment, one short work sample, and a structured interview. Reading a portfolio tells you a candidate produced one good piece once. It does not tell you whether they can hit your brand voice, source a claim, or fix a weak draft on a deadline.

Writing is not a shrinking skill. The U.S. Bureau of Labor Statistics projects employment of writers and authors to grow 4 percent from 2024 to 2034, with a median wage of 72,270 dollars in May 2024. The harder question is how you tell a strong writer from a confident one before they are on your payroll. Get it wrong and you pay for months of thin content and rework. Get it right and you shortlist on evidence, not on who wrote the best cover letter.

TL;DR

• Evaluate content writing skills against a rubric, not a gut reaction, so two reviewers reach the same shortlist.
• Test the skills that matter for the role: grammar, clarity, research, SEO, brand voice, and editorial judgment.
• Use a scored writing assessment before the interview, then a short work sample to see how the candidate really works.
• Map each competency to a specific piece of evidence with the Testlify Competency-to-Evidence Matrix.
• In 2026, add one test the old guides skip: can the writer judge, fix, and improve an AI draft, not just produce words.

Which content writing skills actually matter?

The skills that matter are grammar and mechanics, clear structure, original research and fact-checking, search intent and on-page SEO, brand-voice adaptability, and editorial judgment. Not every role needs all six in equal measure. Decide the weighting before you write the job ad, because that weighting is what your assessment and interview should measure.

Define your core term once and hold to it. “Content writing skill” here means the ability to turn a brief into accurate, readable, on-brand copy that does a job for the reader, not the ability to sound clever. A technical writer leans on accuracy and structure. A brand writer leans on voice and originality. A product marketer leans on clarity and persuasion. Same job title, different evidence to look for.

Skill weighting also shifts with the market. The World Economic Forum reports that 39 percent of workers’ core skills will change by 2030, and it ranks analytical thinking as the top skill employers want, with creative thinking close behind in fourth. For writers, that combination is the whole job: think through a messy topic, then make it land. Screen for both, not just polished prose.

How do you evaluate content writing skills?

You evaluate content writing skills by combining three methods that each cover the others’ blind spots: a scored skills assessment for consistency, a short work sample for real-world behavior, and a structured interview for reasoning. One method alone is easy to game. Together they are hard to fake. Score every step against the same rubric so the shortlist is comparable.

Notice what the table exposes. A portfolio, the thing most teams lead with, is the weakest single signal, because you cannot see who edited the piece or how long it took. That is the core problem with the standard advice of “ask for samples and read them.” It measures the ceiling of a writer’s best day, not the floor of their average Tuesday. Start with the assessment for a fair, comparable baseline, then use samples and interviews to go deep on the few who clear it.

The Testlify Competency-to-Evidence Matrix

The Testlify Competency-to-Evidence Matrix maps every role to the competencies that matter, then connects each competency to measurable evidence through assessments, simulations, interviews, and structured reviewer feedback. The rule is simple: do not start with a test, start with the role. Write down the competencies the writer must have, then decide what evidence would prove each one. If a competency has no evidence source, you are hiring on hope.

Pro Tip: Agree the rubric and the passing bar before the first application lands. When reviewers score against a shared rubric instead of scoring against each other, a two-person hiring panel stops arguing about taste and starts comparing evidence. It is the single fastest way to cut a slow, subjective writer search down to a clean shortlist.

How do you assess SEO writing skills?

Assess SEO writing skills with a short, practical exercise: give the candidate a target query and ask for a title, a meta description, an outline, and the search intent behind it. Then check whether the plan matches what a searcher actually wants, uses the keyword naturally, links to related pages, and still reads for a human first. A resume line that says “SEO” proves nothing. A five-minute planning task proves plenty.

Watch for the two failure modes. The first is the writer who stuffs the keyword until the copy reads like a robot wrote it for another robot. The second is the strong prose writer who ignores intent and writes a lovely essay that answers a question nobody searched. You want the middle: someone who treats the keyword as a promise to the reader and keeps that promise in plain language. If the role is SEO-heavy, weight this competency higher and test it before anything else.

How do you judge writers in the AI era?

Judge writers in the AI era on what a model cannot do for them: judgment, original angle, accurate research, and a real brand voice. McKinsey found that 65 percent of organizations now use generative AI regularly, with marketing and sales among the most common functions. That means every candidate can produce a competent draft in seconds. The value has moved from producing words to knowing which words are wrong, thin, generic, or off-brand, and fixing them.

So test for it directly. Hand the candidate an AI-written draft that has a factual error, a vague claim with no source, and a flat, on-nobody’s-brand paragraph. Ask them to mark it up and rewrite it. A strong writer catches the error, demands a source, and injects a point of view. A weak one polishes the grammar and hands back the same empty draft. This one exercise separates writers who add value from writers who add volume, and no portfolio will show it to you.

This sits inside a bigger idea: the winning model is AI-assisted and human-led. AI can draft and suggest. The writer, and the hiring team, still own the call on what is good enough to publish. Hire for the judgment, not the typing speed.

A worked example: hiring a B2B writer

Picture a 300-person SaaS company hiring one B2B content writer, with 140 applicants and two reviewers who have day jobs. Reading 140 portfolios by hand would take a week and still come down to taste. Instead, the team maps the role first: clarity and SEO weighted high, brand voice medium, long-form research medium. They send every applicant a 20-minute scored assessment covering grammar, comprehension, and a short SEO planning task, drawn from a content writer assessment.

The assessment cuts 140 down to 18 on evidence, in an afternoon rather than a week. Those 18 get one paid work sample: rewrite a real, weak product page. Six clear the sample. Those six reach a structured interview built from a set of content writer interview questions, where every candidate answers the same scored questions. The team hires from six people they have real evidence on, not from 140 cover letters. Same headcount, a fraction of the reviewer hours, and a decision they can defend.

Anchoring the role to a job description keeps the rubric honest. If you are still scoping the role, the copy editor, assistant editor, and copywriter editorial director templates lay out the core competencies to test against. For adjacent roles, the copywriter test and technical writer test cover different weightings of the same six competencies.

Key takeaways

• A rubric beats a gut read. Scoring writers against a shared rubric, not against each other, removes reviewer bias and lets a two-person panel reach the same shortlist. Without it, hiring comes down to whose taste wins the argument.
• Start with the role, then pick the evidence. The Competency-to-Evidence Matrix forces you to name what proves each skill before you test. A competency with no evidence source is a competency you are guessing at, so the guessing shows up later as a bad hire.
• A portfolio is the weakest single signal. It shows a best-case ceiling with no proof of authorship or effort. Lead with a scored assessment for a fair baseline, then use samples and interviews to go deep on the few who clear it.
• Test SEO as a task, not a claim. A short title, meta, and outline exercise for a real query exposes search-intent judgment that no resume line can. Weight it higher when the role is SEO-heavy and test it early.
• Screen for AI-era judgment. When anyone can generate a draft, the value is catching what is wrong, thin, or off-brand and fixing it. An edit-the-AI-draft exercise separates writers who add value from writers who add volume.
• Assessment first saves reviewer time. Scoring every applicant up front cuts a large field to a shortlist in an afternoon, so your senior reviewers spend their hours on the candidates who already cleared the bar.
