Why HR Alone Can’t Handle Technical Talent Evaluation
HR teams excel at managing administrative tasks and coordinating hiring processes, but when it comes to evaluating the technical depth required for modern development roles, they often fall short. The complexities of assessing candidates for tasks like building AI-powered mobile apps or designing machine learning algorithms go far beyond the expertise of most HR professionals. This gap in technical evaluation creates significant hurdles for effective hiring.
The Skills Gap: HR’s Technical Limitations
Most HR professionals lack the technical knowledge needed to assess advanced skills such as Kubernetes containerization, microservices architecture, or natural language processing. A 2021 survey revealed that 64% of HR leaders identified a shortage of tech talent as a barrier to innovation, while 62% admitted they were unable to use people analytics effectively to identify trends.
This disconnect is further compounded by communication challenges between HR and technical managers. For example, evaluating a candidate’s ability to implement OAuth 2.0 security protocols is vastly different from assessing their interpersonal skills. While HR teams are adept at gauging soft skills through behavioral interviews, they lack the technical expertise to determine whether a candidate can design secure, scalable authentication systems.
Overreliance on Resumes and Keywords
HR’s reliance on keyword matching during resume reviews – often completed in just 60–70 seconds – creates a flawed evaluation process. This approach not only leads to job descriptions that fail to accurately reflect the role but also encourages candidates to exaggerate their skills to match keywords. As a result, the hiring process becomes a surface-level exercise that overlooks true technical competency.
Additionally, informal hiring practices like relying on personal networks can introduce "like-me" bias, which stifles diversity and innovation. Generic hiring frameworks often fail to tap into passive talent pools, where many of the most skilled professionals reside. On top of that, polished resumes and cover letters can overshadow genuine technical ability, rewarding candidates who excel at resume writing rather than those with the necessary expertise. These inefficiencies not only misrepresent candidate potential but also lead to missed opportunities and financial losses for businesses.
The Cost of Poor Technical Hiring
Hiring mistakes in technical roles can have steep financial consequences. On average, poor hiring decisions cost 30% of an employee’s annual salary. For executive-level roles, the cost can escalate to 15–20 times their salary when factoring in lost productivity, turnover, and strategic setbacks. The broader impact is even more alarming: IT skills shortages are projected to cost $5.5 trillion globally by 2026.
Inefficient HR-led hiring processes also prolong recruitment timelines, with each additional week reducing offer acceptance rates by 10–15%. This delay can cause companies to lose top candidates to competitors. Moreover, 90% of tech companies report that skills gaps directly hinder project delivery.
The repercussions extend well beyond project delays. When HR teams hire developers who lack the technical skills required, projects often fail to meet expectations, forcing companies to rebuild not just their technology but also their reputation. With AI expected to reshape 70% of job skills by 2030 and nearly half of organizations planning to expand hiring for AI-related roles, businesses can’t afford to rely on outdated hiring practices that don’t account for technical complexity. To address these challenges, companies need domain experts who can accurately evaluate both technical capabilities and their impact on business outcomes.
How Domain Experts Improve Technical Hiring
When domain experts lead the charge in technical hiring, they bring a level of precision that eliminates much of the guesswork. Their in-depth knowledge allows them to go beyond surface-level impressions and pinpoint candidates who can genuinely deliver. Let’s explore how their expertise shapes technical evaluations.
Deep Knowledge of Technical Skills and Tools
Domain experts have the technical insight to evaluate complex skills that traditional HR professionals may not fully grasp. They understand the subtle differences between programming languages, frameworks, and development approaches, which makes their input invaluable.
For instance, a seasoned mobile developer can easily distinguish between a candidate with basic React Native knowledge and someone capable of optimizing it for large-scale applications. Similarly, they can determine whether a candidate truly understands Flutter‘s widget tree or is simply copying solutions from documentation. This level of evaluation requires hands-on experience.
Moreover, domain experts stay informed about emerging technologies and industry shifts. They know which skills are falling out of favor and which are gaining traction. For example, when hiring for AI-focused roles, they can assess a candidate’s practical expertise with frameworks like TensorFlow or PyTorch, ensuring the person can design scalable AI solutions rather than just implement basic models.
This expertise is even more critical when hiring for "hybrid" roles that demand both specialized and generalist skills. These roles are often 30–50% more impactful than purely specialist positions in software. Domain experts are uniquely equipped to identify candidates who excel in both areas, offering a rare blend of technical depth and adaptability.
Practical Problem Solving and Project Tests
The ability to translate technical knowledge into real-world problem-solving is where domain experts truly shine. They design assessments that mimic actual workplace challenges, such as coding exercises, system design tasks, and project-based tests, to evaluate how candidates approach problems in realistic scenarios.
Live coding sessions are particularly revealing. These sessions allow experts to observe how candidates break down complex problems, debug issues, and adapt under pressure. Similarly, pair programming exercises offer a window into both technical skills and teamwork. By working on a task together, the expert can assess how well the candidate communicates technical ideas, responds to feedback, and collaborates to solve problems.
Scenario-based assessments are another powerful tool. For example, a candidate might be asked to optimize a legacy codebase or design a system to meet specific performance criteria. These tests highlight whether a candidate can apply their knowledge to solve practical business problems. Domain experts, with their deep understanding of what good solutions look like, can easily differentiate between clean, maintainable code and quick fixes that may create long-term issues.
Finding Technical and Team Fit
Beyond technical skills, domain experts also evaluate how well candidates will integrate into the team. They understand that the ideal hire isn’t just someone with excellent coding abilities – it’s someone who works well with others, communicates effectively, and boosts overall team productivity.
Using their technical background, domain experts assess how candidates interact during technical discussions. They look for individuals who ask thoughtful questions, actively listen, and contribute meaningfully to conversations.
To further evaluate fit, domain experts often replicate real-world scenarios. For instance, pairing a candidate with a senior developer on a coding task can provide insights into their problem-solving style and how they collaborate under real conditions.
They also consider a candidate’s approach to code quality, testing practices, and decision-making. Does the candidate’s work align with the team’s standards? Will their methods enhance the team’s overall technical output? These are critical questions domain experts are well-equipped to answer.

Common Technical Hiring Mistakes to Avoid
While leveraging domain experts in your hiring process offers clear advantages, avoiding common pitfalls is just as important. Misjudging technical talent is a widespread issue – 75% of employers admit they’ve hired the wrong person at least once. And the cost of replacing a poor technical hire? It can run several times the employee’s annual salary. This makes thorough and effective evaluation a financial necessity.
Combining Technical and Soft Skills Assessment
A frequent misstep in technical hiring is separating the evaluation of technical abilities from the assessment of soft skills. Often, coding skills are tested by domain experts, while HR handles communication and teamwork evaluations. This fragmented approach can leave you with an incomplete understanding of how a candidate will perform within your team.
The better strategy is to integrate these assessments throughout the hiring process. Domain experts shouldn’t just focus on whether a candidate can write efficient code – they should also observe how the candidate communicates their thought process during problem-solving. For example, does the candidate ask insightful questions? Can they explain a technical concept in a way that’s easy to grasp? These soft skills are critical for collaboration in any development environment.
"Call in experts for tech hires. Tech talent tends to have very particular, specific, and measurable skill sets. It’s important that someone in the hiring decision knows what to ask about and test for." – Meghan M. Biro
One way to achieve this is by having domain experts and HR professionals collaborate during key phases of the evaluation process. For instance, during a live coding session, the domain expert can assess technical proficiency, while HR observes communication style and team compatibility. This joint effort ensures no important aspect of the candidate’s overall suitability is overlooked.
By integrating these assessments, you lay the groundwork to avoid other common errors in technical hiring.
Don’t Rely Too Much on Certifications
Certifications and polished resumes can be misleading. While they might make a candidate look impressive on paper, they don’t necessarily reflect the ability to handle real-world challenges or adapt to your company’s specific technical needs. Resumes are often self-reported and lack the depth needed to evaluate true capability.
This issue becomes even more problematic when candidates exaggerate their qualifications. You might hire someone who seems ideal on paper but struggles with basic problem-solving once hired. Practical assessments designed by domain experts are essential to uncover a candidate’s actual skills.
"Resumes lack depth on skills and personality; use assessments and interviews to get a comprehensive view of candidates’ fit." – Yash Patel, WordPress Developer, Testlify
Instead of placing too much weight on certifications, focus on skills-based evaluations that mimic real work scenarios. For instance, a candidate might not have the latest certification in a specific framework but could demonstrate adaptability and problem-solving abilities that make them a strong fit. Overemphasizing certifications risks overlooking self-taught or non-traditional candidates who could excel in the role.
Domain experts play a crucial role here by prioritizing practical tests over paper credentials, ensuring you hire for capability rather than appearances.
Creating Fair and Clear Evaluation Processes
Inconsistent evaluation methods can lead to poor hiring decisions and even open your company to bias or legal risks. When candidates face different types of assessments or evaluation criteria, hiring becomes more of a gamble than an informed decision-making process.
Research from Harvard Business Review highlights how unintentional biases can affect evaluations. For instance, candidates from underrepresented groups often receive lower ratings despite having equal qualifications and performance. To counter this, it’s essential to implement standardized evaluation processes. Define the technical requirements for each role and establish clear criteria for assessing performance. Whether it’s coding challenges, technical questions, or scoring rubrics, ensure every candidate is evaluated using the same standards.
Documentation is another key element. Record each candidate’s performance and the reasons behind evaluation decisions. This not only helps you make better hiring choices but also protects your company from potential discrimination claims.
Diverse interview panels can also help reduce bias. Including domain experts from different backgrounds ensures multiple perspectives are considered, leading to fairer evaluations. Plus, Glassdoor research shows that 77% of job seekers are more likely to accept an offer from a company that provides clear and timely feedback. A standardized process with transparent communication can improve both candidate experience and hiring outcomes.
Treat the evaluation process as a structured system rather than a series of informal conversations. When domain experts follow consistent protocols, they can focus on identifying candidates who will genuinely contribute to your technical team’s success. By avoiding these mistakes, you create a hiring strategy that aligns domain expertise with better hiring outcomes.
Building a Domain Expert-Led Hiring Process
Now that you’re aware of the common mistakes to avoid, it’s time to create a structured system that puts domain experts at the heart of your technical hiring process. The goal? Build a repeatable framework that consistently identifies top technical talent while staying efficient and fair. Here’s how to turn hiring challenges into a solid evaluation process.
Setting Role-Specific Evaluation Standards
A strong technical hiring process starts with clarity – what exactly are you looking for? Collaborate with domain experts to pinpoint the critical skills, knowledge, and competencies required for each role. These experts understand the day-to-day realities of the work and can identify the nuances that matter most.
Bring together hiring managers, senior developers, and HR to outline detailed, role-specific requirements. These should cover both technical expertise and team compatibility. For example, hiring a mobile app developer might require experience with performance optimization, an understanding of platform-specific design principles, or expertise in securing sensitive data. These specifics often go unnoticed by HR alone, which is why domain experts should lead this step.
Once you’ve defined the requirements, document them clearly. Create scoring rubrics that outline what “excellent,” “good,” and “needs improvement” look like for each skill. This helps maintain consistency across evaluations and ensures domain experts focus on the most important areas. Start with initial screenings to verify baseline technical qualifications, and save in-depth evaluations for candidates who meet those minimum standards.
Using Tools and Technologies for Assessment
The right tools can make all the difference in evaluating candidates effectively. Modern assessment platforms go beyond basic coding challenges, offering a way to measure both technical skills and team compatibility.
Coding platforms are particularly useful for assessing practical skills. These tools let domain experts see how candidates approach real-world problems instead of abstract puzzles. Some platforms even support collaborative coding sessions, which allow you to evaluate technical ability and communication skills simultaneously.
When selecting tools, make sure they integrate smoothly with your hiring process. They should align with your goals and work seamlessly with your applicant tracking system. Consider not only the upfront cost but also the long-term benefits, like saving time for domain experts and improving the quality of hires.
AI-powered tools can also help by providing data-driven insights, allowing domain experts to focus on the most promising candidates. Tailor these tools to the unique demands of each role – what works for a backend API developer might not suit an augmented reality specialist.
