{Technical vs Soft Skills Assessment Methods and Success Metrics in Tech Hiring}
How to Assess Technical Skills
Evaluating technical skills goes far beyond solving puzzles. The methods you use should align with the role's demands and the candidate's level of experience. For example, a junior developer and a senior architect require completely different assessment approaches, and your strategy should reflect those distinctions.
There are three standout methods for assessing technical skills: live coding interviews, take-home projects, and system design challenges. Live coding lets you observe how candidates think and communicate under real-time conditions. Take-home projects give candidates space to demonstrate their coding habits and problem-solving skills without the pressure of being observed. System design challenges focus on senior candidates, testing their ability to architect scalable solutions while balancing competing technical priorities. Let’s break these down further to understand how they work.
Practical coding challenges are far better predictors of job performance than traditional algorithmic interviews. Research shows they have a 91% accuracy rate, compared to just 67% for whiteboard-style tests . This explains why some candidates excel in theoretical tests but struggle with actual job tasks.
Tailor your assessments to the role. For instance, a front-end developer should be tested on responsive design, not abstract data structures. Similarly, a back-end engineer should demonstrate API design skills rather than memorizing sorting algorithms. A great example comes from GitLab’s frontend engineering team, which implemented a standardized process in 2020 using their open-source project-seeder tool. This tool assigned candidates specific merge requests to troubleshoot while allowing them to use resources like the GitLab Handbook and the internet. This "open-book" approach, led by Manager Clement Ho, created a more realistic and inclusive evaluation environment as the team scaled from 400 to 1,300 engineers .
Keep assessments concise and focused. The ideal length is around 60–70 minutes - long enough to gather meaningful insights without overburdening candidates . Candidates who pass multi-stage technical evaluations tend to perform 87% better in their first 90 days compared to those screened using traditional methods . This is because the assessments prioritize practical skills over theoretical knowledge.
Live Coding Interviews
Live coding interviews provide a window into how candidates think under pressure, articulate their reasoning, and solve problems in real time. The goal is to make these sessions feel like real work rather than a high-stakes test. Encourage candidates to think out loud as they code. This helps you understand their problem-solving approach, even if they don’t complete the task.
Set up the environment to mimic real-world conditions. Allow candidates to use their preferred IDE or development tools, and observe both their technical skills and how they respond to feedback. Be cautious of "environment friction", which can unfairly disadvantage candidates who are otherwise skilled. For roles requiring teamwork, consider pair programming sessions where candidates collaborate with a current team member.
Focus on challenges that mirror your team’s actual work. For instance, if your team frequently debugs APIs, design a live coding task around API troubleshooting. If database optimization is a key responsibility, craft a challenge around improving query performance.
Live coding can sometimes lead to false negatives, as some candidates may freeze under observation. To counter this, keep the session conversational and emphasize that you value their thought process over perfect syntax. Some companies now offer candidates the choice between live coding and take-home projects to accommodate different working styles and stress levels.
Take-Home Projects
Take-home assignments allow candidates to showcase their skills in a more relaxed and familiar environment. These projects highlight coding style, attention to detail, and how candidates approach realistic business problems. For example, a front-end role might involve implementing a design mockup, while a back-end position could focus on building a small API with proper error handling.
Respect candidates' time by keeping these assignments short - ideally under two hours . Longer projects often discourage participation, especially for candidates who are already employed.
Provide clear instructions and evaluation criteria upfront. Candidates should know exactly what you’re looking for, whether it’s code quality, test coverage, documentation, or specific functionality. Using a standardized rubric with objective categories like "Error Handling", "Code Organization", and "Responsiveness" can help reduce bias and ensure fair comparisons.
Take-home projects offer insights that live coding can’t, such as how candidates structure larger codebases, document their work, and handle edge cases when given adequate time to think through solutions.
System Design Challenges
System design interviews are ideal for assessing whether candidates can architect scalable solutions, make informed trade-offs, and think beyond individual features to entire systems. These challenges are particularly relevant for senior roles, where developers need to design infrastructure capable of handling high traffic, managing data at scale, or integrating multiple services.
Tailor the scenarios to your company’s specific needs. For example, if you run a high-traffic e-commerce platform, ask candidates to design a product recommendation system. If your focus is SaaS applications, explore how they would architect multi-tenant data isolation. This approach ensures that candidates are tested on real challenges they’ll face, rather than generic textbook problems.
System design discussions should be collaborative. Encourage candidates to ask clarifying questions about requirements, user scale, and constraints. Strong engineers know that effective architecture depends on understanding the business context - there’s no one-size-fits-all solution without knowing the trade-offs involved.
These interviews are harder to standardize than coding tests and require experienced interviewers who can objectively evaluate architectural thinking. Using a rubric that covers areas like scalability, data modeling, technology choices, and trade-offs between performance, cost, and complexity can help ensure a thorough and fair assessment.
Next, we’ll explore how to evaluate soft skills with the same level of care and precision.
How to Evaluate Soft Skills
Soft skills are just as crucial as technical expertise in tech roles. In fact, 92% of talent professionals agree that soft skills are just as important - if not more so - than hard skills . These abilities, including communication, teamwork, adaptability, and problem-solving, require a structured evaluation process. Using an organized approach ensures you find candidates who not only meet technical requirements but also align with your team's working style and needs.
Two highly effective methods for assessing soft skills are behavioral interviews and situational role-plays. Behavioral interviews focus on uncovering past experiences through frameworks like STAR (Situation, Task, Action, Result), while situational role-plays simulate real-world challenges to evaluate how candidates respond in the moment. Both methods should be tailored to the specific demands of your team, such as remote collaboration, cross-functional communication, or managing shifting project priorities.
Behavioral Interview Techniques
Behavioral interviews rely on the STAR method to extract examples of past behavior, which can often predict future performance. Questions typically start with prompts like "Tell me about a time when..." and encourage candidates to walk through the Situation, the Task they faced, the Action they took, and the Result of their efforts .
For tech roles, you can focus your questions on scenarios that reflect your team's priorities:
Communication: Ask candidates to describe a time when they needed to explain a technical concept to non-technical colleagues. For example: "Tell me about a time when you were the technical expert and had to ensure everyone understood your explanation" . Strong candidates will share how they simplified complex ideas, ensured understanding, and adjusted their approach based on their audience. Another question could be: "What did you do when someone didn’t understand your explanation?" . Look for responses that show patience and adaptability.
Teamwork: To assess interpersonal skills, ask: "Can you give an example of working with someone difficult? How did you handle it?" . Pay attention to whether the candidate demonstrates empathy and a willingness to find common ground. Another useful question is: "Tell me about a time when you needed information from someone who wasn’t very responsive. How did you handle it?" . This can reveal persistence and creative problem-solving.
Adaptability: In fast-changing environments, flexibility is key. Ask: "Tell me about a time when you were asked to do something you’d never done before. How did you react, and what did you learn?" . Strong answers often reflect enthusiasm for new challenges and a willingness to step out of their comfort zone. Another option is: "Describe a situation where you adopted a new system or technology that was a big shift from the old way of doing things" . Look for candidates who embrace change rather than resist it.
When reviewing responses, pay close attention to the balance between "I" and "we" statements . Candidates who only focus on "I" may struggle to collaborate, while those who only use "we" might not clearly articulate their individual contributions. If a response feels overly rehearsed, follow up with more specific or hypothetical questions to encourage genuine, on-the-spot thinking . To keep evaluations consistent and objective, use a standardized scorecard with clear rating criteria for all candidates .
Situational and Role-Play Scenarios
Situational scenarios and role-plays offer a window into how candidates navigate challenges in real time. Unlike behavioral interviews, which focus on past experiences, these exercises test how candidates think and act on the spot. This approach is especially valuable since teams that prioritize collaboration are five times more likely to achieve high performance .
Design scenarios that reflect the realities of your team’s work. For instance:
- If your team often communicates with non-technical stakeholders, create a role-play where the candidate explains a complex technical concept in simple terms. You might ask them to "explain this to me like I’m five" to gauge their ability to simplify and clarify .
- For remote teams, simulate a scenario where the candidate needs to resolve a misunderstanding over Slack or a video call. This tests emotional intelligence, patience, and problem-solving under virtual conditions .
Another effective method is collaborative live coding. Instead of having candidates solve problems solo, pair them with a team member to tackle a challenge together. This setup reveals whether they see the task as a shared effort or try to dominate the process . Watch for proactive communication, openness to feedback, and clear explanations of their thought process. As Jocelyn Goldfein from Zetta Venture Partners notes:
"We want to hire people whose top priority when things go wrong is to solve the problem, not to evade blame" .
After any role-play or situational exercise, hold a debrief session to dive deeper into their reasoning . Ask questions like: "If you had more time, what would you do differently?" or "What risks did you identify, and how would you address them?" . These discussions provide insight into their critical thinking, self-awareness, and ability to reflect on their performance. The goal is to understand not just what they did, but why they made those choices and how they’d approach similar situations in the future.
Tools and Frameworks for Better Assessments
Leveraging the right technology can take hands-on assessments to the next level, offering a more streamlined and structured way to evaluate candidates. Modern tools not only simplify technical evaluations but also provide insights into soft skills. By incorporating AI-powered platforms and integrated systems, you can go beyond subjective evaluations and create a consistent, efficient process. These tools complement human judgment by automating repetitive tasks and highlighting top talent. Let’s dive into how AI-driven screening and ATS integration can improve candidate assessments at every stage.
AI-Powered Assessment Tools
AI platforms are revolutionizing the initial screening process, which has traditionally been a time-intensive task for recruiters. Take daily.dev Recruiter, for example. This platform uses AI to sift through a community of over 1,000,000 developers, helping you quickly identify qualified candidates without manually reviewing countless profiles . It connects you with developers actively engaged in learning, which often signals both technical expertise and a growth mindset.
One of the standout benefits is automated technical screening. With these tools, you can define role-specific criteria - like proficiency in certain programming languages, experience with specific frameworks, or contributions to open-source projects. The AI then evaluates candidates against these benchmarks, ensuring every applicant is assessed objectively and fairly. This approach minimizes early-stage bias and ensures consistency across all evaluations. Additionally, because daily.dev Recruiter operates within an active developer network, it often surfaces passive talent - professionals who aren’t actively job hunting but are open to the right opportunity. This not only increases response rates but also fosters more meaningful interactions.
Applicant Tracking System (ATS) Integration
When assessment tools integrate seamlessly with your ATS, your hiring process becomes much more efficient. By syncing technical screening results and AI-generated insights directly into a candidate’s profile, you create a centralized system for your hiring team. This eliminates the hassle of juggling spreadsheets or manually transferring data, giving you a single, real-time view of each candidate.
Automated workflow triggers add another layer of efficiency. For example, your ATS can automatically send out technical assessments or behavioral surveys when a candidate advances to a specific stage in your pipeline. This ensures no steps are missed and reduces administrative tasks. Imagine this: when daily.dev Recruiter identifies a qualified developer, their information flows directly into your ATS, allowing you to seamlessly move them from discovery to interview scheduling. Real-time syncing also means interviewers have immediate access to assessment results during live sessions, enabling more informed and productive discussions. This kind of integration lays the groundwork for a cohesive, data-driven approach to technical interviews, which will be explored further in the next section on best practices.

Best Practices for Balanced Tech Interviews
Creating an effective interview process goes beyond simply having the right tools - it requires a well-thought-out structure that ensures fairness for candidates while addressing your organization's specific needs. The goal is to move away from subjective "gut feelings" and focus on structured, data-driven evaluations. By designing interviews with clear, consistent criteria, you’ll not only make better hiring decisions but also leave candidates with a positive impression of your company. A good starting point is defining role-specific criteria to ensure assessments are both relevant and objective.
Define Role-Specific Criteria
Start by outlining what success looks like in the role you’re hiring for. Collaborate with your engineering team to identify the specific Knowledge, Skills, Abilities, and Other characteristics (KSAOs) that are essential for the job. Focus only on what’s truly necessary.
For each requirement, ask yourself why it’s important. For example, if you’re asking for responsive CSS skills, it should be because the role involves implementing designs - not just because it sounds impressive. This approach helps eliminate unnecessary requirements that might screen out qualified candidates . Companies that prioritize real-world problem-solving skills over generic programming concepts see 30% better hiring outcomes .
Work with your in-house developers to create a library of coding questions that reflect actual challenges your team faces. Instead of relying on generic algorithm puzzles, use problems that mimic your work environment. Tailoring tasks to your industry can lead to higher completion rates . Also, establish clear benchmarks for what “technical excellence” means for the role, whether it’s expertise in a specific platform, the ability to handle complex problems quickly, or something else.
Combine Technical and Soft Skill Assessments
The best interviews evaluate candidates on multiple levels, blending technical and interpersonal skills rather than treating them as separate categories. For example, during live coding sessions, ask candidates to explain their thought process and trade-offs. This lets you assess both their technical ability and their communication skills at the same time.
Structure your interview process so that technical and behavioral evaluations flow naturally. Begin with a simple warm-up coding exercise to help the candidate feel at ease, then move on to a more challenging problem where they can explain their approach. Strong communication can increase productivity by 25% , so observing how candidates articulate their decisions offers valuable insight into their potential impact.
Give candidates the option to choose their assessment method. Some may prefer a live coding session, while others might feel more comfortable with a take-home project. Offering this flexibility accommodates different personality types and stress levels . However, keep take-home projects manageable - limit them to 3–4 hours to avoid discouraging senior candidates who might have less time. The real value of take-home tasks comes during the follow-up discussion, where you can evaluate the solution and the reasoning behind it.
Reduce Bias and Improve Candidate Experience
Structured interviews are one of the best ways to minimize bias. Use the same set of questions in the same order for all candidates, and rely on a clear scoring rubric with numerical values. For example, Jamie Talbot, former Director of Engineering at Medium, introduced a structured rubric in November 2022. This method shifted the team’s focus from subjective impressions like “the candidate seemed like a team player” to objective observations such as “the candidate provided specific examples of collaborating with others” .
"You can overcome bias with a structured interview process that asks the same set of questions for all candidates. This ensures you evaluate each candidate based on his or her responses, rather than on preconceived notions." - Lissa Harr, Senior Director of Talent Acquisition, DataBank
Streamline your process to ensure a better experience for candidates. A simple 3-tier scoring system - Full, Partial, or No Credit - can help reduce grader subjectivity . This is especially important given that 65% of technical recruiters report bias in their current hiring processes . Before implementing a new rubric, hold calibration sessions where multiple interviewers independently score the same interview to ensure consistency.
Enhance the candidate experience by offering preparation resources. Share sample questions or mock environments to help level the playing field and reduce anxiety . Providing post-assessment feedback, even if brief, can set your company apart and boost your reputation. Regularly track candidate dropout rates and pass rates to identify whether an assessment is too challenging or irrelevant to the role.
Conclusion
Building tech teams that excel goes beyond just evaluating coding abilities. While technical skills address the complexities of software development, soft skills ensure teams can collaborate effectively and adapt to evolving challenges. By focusing on both areas during interviews, you're setting the foundation for teams that communicate well and handle shifting priorities with ease.
The approaches outlined earlier help you evaluate candidates from a well-rounded perspective. Begin with clear, role-specific criteria that define success for your organization. Then, implement structured rubrics to reduce bias and offer candidates transparent preparation guidelines. This structured approach lays the groundwork for incorporating advanced tools into your hiring process.
Platforms like daily.dev Recruiter simplify this journey by connecting you with a community of over 1,000,000 developers dedicated to continuous growth. With warm, double opt-in introductions, you gain access to pre-qualified candidates ready to contribute to your team.
