How to vet freelancers: skills tests, interviews and red flags

A great freelancer can transform a project. A poor fit can cost you months of time, rework and lost momentum. Vetting is how you tell the difference before you commit.

The good news: you do not need a complicated process. You need a few strong signals, collected consistently. This is the approach we use at HireCurated, adapted so you can apply it yourself.

Step 1: Screen the profile

The first pass should take a few minutes per candidate. Look for:

• Relevant experience, not just years. Five years building products like yours beats ten years of unrelated work.
• Proof of work. GitHub, live products, case studies, Dribbble or Behance, published campaigns, writing samples.
• Clarity. A clear, specific profile usually means clear communication on the job. A vague one usually means the opposite.
• Fit with your engagement. Availability, rate and time zone that match your needs.

Cut aggressively here. It is better to spend serious time on four strong candidates than a little time on twenty.

Step 2: Review real work together

Ask each candidate to walk you through one project close to yours. Guide the conversation with a few questions:

• What was the problem, and who was it for?
• What exactly was your role, and what did others do?
• What were the hardest decisions, and why did you choose what you chose?
• What would you do differently now?

You learn more from this conversation than from any CV. Strong candidates speak precisely about their own contribution, explain trade-offs and are honest about mistakes.

Step 3: Use a practical skills test

The best tests look like the real job, at a small scale:

• Developers: a small feature or bug fix in a realistic codebase, or a code review exercise on an existing pull request.
• Designers: a short design challenge with real constraints, or a critique of an existing flow.
• Product managers: prioritize a sample backlog or write a short spec for a feature.
• Data experts: answer a business question with a sample dataset and explain the answer.
• Marketers: outline a campaign or audit a landing page and its funnel.

Keep tests to two to four hours, or pay for anything longer. Respecting candidates' time attracts better candidates, and paid trials give you a more realistic picture. See paid trial projects.

How to score a test

Decide on criteria before you look at any submissions, and score each one separately:

1. Did it solve the actual problem?
2. Quality: structure, readability, attention to detail
3. Judgment: sensible trade-offs, explained clearly
4. Communication: a short note explaining what they did and why

A simple 1-to-5 score per criterion makes comparing candidates much fairer.

Step 4: Interview for remote work

Skills are only half of the picture. Remote work depends on communication and self-management. Ask:

• How do you report progress to clients?
• Tell me about a time requirements changed in the middle of a project.
• How do you handle being blocked while the rest of the team is offline?
• How many overlap hours can you commit to, and when?
• How do you estimate work, and what do you do when an estimate turns out wrong?

Also notice how they behave during the hiring process itself: response times, clarity of messages, punctuality. It is a preview of the job. Our list of interview questions for freelancers has many more.

Step 5: Check references

A short call with a past client often reveals what interviews do not: reliability, communication under pressure and whether they would hire the person again. Ask specific questions:

• What did they work on, and for how long?
• How was their communication when things went wrong?
• Would you hire them again for a similar project?

Red flags

• Vague answers about their own role in past projects
• No examples of work, and no explanation why (NDAs are common, but a good freelancer can still describe the work)
• Saying yes to every skill, every timeline and every budget
• Slow or careless communication during the hiring process
• Pressure to start immediately without a written agreement
• Unwillingness to do any kind of test or trial, paid or not
• Badmouthing every previous client

Green flags

• Asking sharp questions about your goals, users and constraints
• Pushing back respectfully on an unrealistic timeline
• Clear, structured written communication
• Specific examples with measurable outcomes
• Honesty about what they do not know
