How to Evaluate Technical Talent When You're Not Technical

If you are non-technical, hiring engineers feels like hiring a contractor for work you cannot inspect. You see the resume, you read the references, you make a bet. The bet is right about 60% of the time. Here is how to push that number higher without becoming a technical evaluator yourself.

What to actually evaluate

Strong engineers consistently demonstrate four things. None of them require you to read code.

Communication. Can they explain a technical decision to a non-technical person without being condescending or unclear? This is a job requirement, not a nice-to-have. You should be able to walk away from a 30-minute conversation with a strong engineer understanding what they would do and why, even on topics you do not know.

Judgement. When you describe a problem, do they push back on the framing, ask about constraints, and offer multiple solutions with tradeoffs? Or do they jump immediately to one solution? Junior-thinking engineers pick. Senior engineers compare.

Ownership. When you ask about their last project, do they talk about what they shipped and learned, or do they talk about what their team did? Strong engineers own outcomes, including the failures. They use "I" and "we" appropriately, not exclusively one or the other.

Real curiosity about the business. Did they ask about your users, your business model, your competitive position? Or did they only ask about the tech stack and the comp? Engineers who care about the business build systems that serve the business. Engineers who do not, build systems that please themselves.

The signals you should ignore

"Years of experience." Useful as a rough sort but a terrible predictor of job-specific success. A 5-year engineer who has been in a sleepy enterprise is often less effective than a 2-year engineer who has been in a fast-moving startup.

"Worked at Google/Meta/Stripe." Real signal. Also produces engineers who are great at scale problems and lost at scrappy startup work. Evaluate the actual fit.

"Hot programming language they know." Languages are mostly fungible at the senior level. Strong engineers pick up languages quickly. The frame you should use is "do they think well," not "do they know our specific stack."

How to set up the interview without being technical

Three things make this work.

Get a technical second opinion. A trusted advisor, a fractional CTO, a friend who is a senior engineer. They do one technical conversation with each finalist (60 to 90 minutes) and give you a written assessment. You do not have to evaluate code; you delegate that piece.

Use a work sample. Give finalists a 4-hour paid take-home that simulates real work. Have your technical advisor evaluate the output. This is one of the single best predictors of job performance.

Talk to three references for each finalist. Two former managers, one peer. Specific questions: "Tell me about a time they disagreed with you. What happened?" "What would you tell me to watch out for?" "Would you hire them again? At what kind of company?"

The non-negotiables

A few things should disqualify a candidate immediately regardless of how strong they seem otherwise.

• Speaks dismissively about former coworkers or former companies.
• Cannot explain a single past project in terms of business impact.
• Has not asked you a single substantive question about the business by the end of the interview.
• References are evasive or hard to schedule.
• Compensation expectations are so far above market that you suspect they are not actually interested.

None of these require technical evaluation. All of them are red flags that survive the technical loop.

The trap to avoid

Founders who are non-technical sometimes over-defer to the candidate or to their technical advisor. The result is a hire chosen for technical excellence who is wrong for the founder relationship or the business stage. You are the founder. You are evaluating the human, the fit, and the judgement. You can and should trust your gut on those even when you cannot evaluate the code.
