How to Assess a Developer’s Skills Without Technical Knowledge

Hiring a skilled software developer is crucial for any business, but assessing technical expertise can be challenging when you lack a technical background. This guide offers practical strategies to help non-technical founders, hiring managers, and HR professionals confidently evaluate developer skills and make the right hire for their team.

This article is part of our Ultimate Guide to Hiring Software Developers series that covers everything from developer hiring models to cost considerations and best practices.

Why Assessing Developer Skills is Essential

Hiring developers without fully understanding their skills can lead to costly mistakes, wasted resources, and project delays. A well-rounded hiring approach balances technical skills, problem-solving, and cultural fit to ensure you’re bringing on a developer who will succeed in your organization.

Define Key Requirements for the Role

Start by defining what you need from a developer based on your project goals. Break down your requirements into the following areas:

Technical Skills Needed: Identify the programming languages, tools, or frameworks essential for your project. For example, do you need a mobile app developer or a data scientist?
Experience Level: Decide if you need a junior developer for simpler tasks or a senior developer for more complex projects.
Soft Skills and Cultural Fit: List qualities such as communication skills, problem-solving, and adaptability, which are crucial for a developer’s success, especially in a startup or collaborative environment.

With clear requirements, you’ll have a reference point to assess candidates effectively, even if you lack technical knowledge.

Use Technical Assessment Tools and Platforms

Several technical assessment tools are designed to help non-technical recruiters evaluate developer skills. Here are some popular options:

Codility: Offers pre-made coding challenges and real-world simulations, allowing you to see how developers approach problem-solving.
HackerRank: Provides customizable coding tests and skill assessments for various technical roles, including frontend, backend, and mobile development.
CodeSignal: Features role-based assessments and industry-standard tests that are great for measuring practical coding skills.
Gun.io: Connects companies with pre-vetted freelance developers, which removes much of the vetting work. Gun.io’s talent is curated for both skills and experience.

These platforms provide scoring and detailed reports that can guide you through interpreting test results, helping you identify the best-fit candidates.

Focus on Problem-Solving and Analytical Skills

A developer’s problem-solving ability is just as important as their technical expertise. Here’s how to assess this:

Ask Hypothetical Scenarios: Present a real-world problem related to your business (e.g., “How would you improve the performance of a data-heavy web page?”) and observe their approach.
Evaluate Logical Thinking: Look for structured, clear explanations, and ask follow-up questions to see how they adapt their solutions.
Check for a Testing Mindset: Skilled developers consider edge cases and look for potential issues before implementing solutions. See if they mention testing or debugging as part of their solution.

Problem-solving discussions reveal how a developer thinks and if they can approach challenges logically, even if the exact technical details aren’t fully explained.

Use Portfolio and Past Work Examples

A developer’s portfolio can provide valuable insights into their skills and approach:

Ask for GitHub Repositories or Live Demos: Reviewing a developer’s GitHub repositories or live projects offers a first-hand look at their code, which you can show to a technical advisor or another developer for feedback.
Review Project Complexity: Look for projects similar to what they’d work on in your business. Complex projects often indicate higher-level problem-solving and planning abilities.
Look for Documentation and Code Quality: Clear documentation and organized code suggest strong communication skills and a structured approach—qualities that matter even more if you’re hiring a remote software engineer.

Evaluating a developer’s past work helps you see real-world applications of their skills without needing to dive into the technical specifics.

Conduct a Soft Skills Interview

Soft skills are essential for a developer’s success, especially when collaborating with non-technical team members. During interviews, assess the following:

Communication Skills: Can they explain technical concepts in a way that makes sense to non-technical people? This is especially important for teamwork and conveying project updates.
Adaptability and Flexibility: Ask about how they handle project changes or unfamiliar tasks. An adaptable developer will more easily overcome learning curves and unexpected project needs.
Time Management and Prioritization: Inquire about their approach to balancing multiple projects or tasks. This is particularly useful if you’re hiring freelance developers who may be juggling multiple clients.

By focusing on soft skills, you can determine if a developer will integrate well with your team and communicate effectively, even if you can’t evaluate their technical abilities.

Consider a Contract-to-Hire Model

The contract-to-hire approach allows you to bring on a developer for a defined period with the option to hire them full-time if they prove to be a good fit. This model can be advantageous when you’re unsure about a candidate’s skills or fit for the team. Here’s how to approach it:

Set Clear Performance Metrics: Outline goals and metrics to evaluate success during the contract period.
Observe Work Quality Over Time: Monitor their problem-solving, productivity, and communication style in real scenarios.
Review Cultural Fit: Assess how well they integrate with your team’s values and collaboration style.

A contract-to-hire model offers flexibility and reduces hiring risk, making it an ideal option for non-technical hiring managers looking to make informed, gradual hiring decisions.

Additional Tips for Non-Technical Hiring Success

Ask for Referrals from Trusted Sources: Reach out to industry contacts or use platforms like Gun.io to find developers vetted by other clients.
Look for Testimonials and Recommendations: Testimonials from past clients or coworkers can provide insights into a developer’s strengths and working style.
Assess Growth Mindset: Developers who stay updated with new technologies and have a continuous learning mindset often bring extra value to the team.

Conclusion: Confidently Hiring Developers Without Technical Expertise

While assessing a developer’s skills can be daunting without a technical background, using the right tools and strategies will help you evaluate their potential effectively. By focusing on soft skills, leveraging technical assessments, using contract-to-hire options, and bringing in third-party experts when needed, you’ll be well-equipped to make informed hiring decisions. Remember, a well-rounded approach ensures you hire a developer who not only meets your technical needs but also aligns with your team’s values and goals.
