Hiring a developer is ultimately a bet on someone’s judgment as much as their technical skill — and judgment is much harder to evaluate from a resume or portfolio alone. A structured vetting process, applied consistently across candidates, dramatically improves the odds of finding someone genuinely capable of handling the project at hand.
Start With Technical Questions That Reveal Real Understanding
Rather than asking generic interview questions, focus on scenario-based technical questions specific to the project. Ask how a candidate would approach a particular problem, what tools or approaches they’d use, and why. Candidates with genuine expertise tend to give nuanced, specific answers, while those with more surface-level knowledge often default to vague generalities.
Request a Small Paid Test Project
For significant hires, a small, clearly scoped paid test project offers far more insight than any interview conversation could. It reveals not just technical skill, but communication style, how the candidate handles ambiguity, and whether they deliver on time. This step also protects both parties — the business gets a real look at working with the candidate, and the candidate gets fairly compensated for their time.
Check Real References, Not Just Listed Ones
Candidates naturally provide references likely to speak positively about them. Going a step further — asking specific, pointed questions about communication, problem-solving under pressure, and how the candidate handled disagreements or setbacks — tends to surface far more useful information than a general “would you recommend them” question.
Review Code Quality, Not Just Finished Output
If possible, review actual code samples rather than just the finished visual product. Clean, well-organized, properly documented code suggests a developer who thinks about long-term maintainability, while messy or undocumented code — even if the final output looks fine on the surface — often creates real problems down the line when changes or fixes are needed.
Evaluate Problem-Solving Under Constraints
Ask candidates to describe a time a project didn’t go as planned and how they handled it. Genuine, specific answers that include what went wrong and what they learned tend to indicate stronger judgment than polished, overly rehearsed success stories that avoid any mention of difficulty.

The Bottom Line
Thorough vetting takes more time upfront, but it consistently prevents the much larger cost of discovering a poor fit only after real project work has already begun.

FAQs
Is a paid test project really necessary before hiring?
For significant or complex hires, yes. It reveals real working style and technical ability far more reliably than an interview conversation alone.
What should I ask for references beyond a general recommendation question?
Ask specific questions about communication style, how the candidate handled setbacks, and whether they delivered consistently on agreed timelines.
How do I evaluate code quality if I’m not technical myself?
Consider bringing in a technical advisor to review samples, or focus vetting more heavily on references, past client feedback, and a structured test project.
What’s a good technical question to ask during vetting?
Scenario-based questions specific to the actual project tend to reveal more than generic questions, since they show how a candidate approaches real problems.
How much time should vetting realistically take?
For significant hires, expect one to two weeks for a thorough process including interviews, a test project, and reference checks.
