In a candidate-short market with high levels of competition for top talent, it's more important than ever to create an engaging and human candidate experience. But you need to balance that with finding the best talent for your role.
Traditional hiring is growing more unreliable daily, costing companies time and money. Resumes are misleading, interviews introduce bias, and skill gaps widen despite recruiters' efforts. To bridge these problems, skills testing is gaining ground in recruitment, changing the focus from perceived skills and background to what candidates can actually do.
This gives recruiters a competitive advantage in today's job market. Candidates hired on real skills rather than background tend to stay longer and perform better over the long term. In this guide, we'll cover everything you need to know about using skills testing in your hiring process.
Skills testing vs traditional hiring
Skills testing takes a skills-first approach to candidate evaluation, assessing them based on their performance in tasks that mirror the job. Here, recruiters test candidates with assessments to provide an unbiased, validated evaluation of a candidate's ability to perform the duties listed in the job description. Many skills tests include immersive experiences, like coding challenges or job simulations, to mimic a candidate's performance in a real-life scenario.
On the other hand, traditional hiring relies solely on what candidates say they can do and their background. It focuses on credentials like education, past experiences, interview performance, and self-reported skills, making hiring decisions based on subjective impressions rather than visible performance.
Why does traditional hiring fail?
Traditional hiring is more ineffective than ever, and many recruiters are searching for more reliable recruitment strategies. Below are four reasons why traditional hiring fails to deliver great hires.
1. Poor predictors of job success
Traditional hiring provides only a high-level view of a candidate's credentials and work experience, and these items don't offer qualitative insight into on-the-job performance. Recent studies show that traditional hiring methods, such as unstructured interviews, have very low predictive validity compared to skills-based methods.
For example, a developer with a prestigious degree may not have the coding skills you require. Similarly, a great interview performance doesn't guarantee a good employee, especially from personalities that build rapport easily.
2. Introduces hiring bias
Research from Zippia revealed that 48% of HR managers admit bias affects their candidate choice. Candidates with certain qualities - whether high-profile degrees, work experience, demographics, or personalities - can resonate more with hiring managers.
Unconsciously, recruiters overlook other qualified candidates who don't fit their desired mold, reducing diversity and access to top-rated, quality talent.
3. Resumes can be misleading
The person you think you're hiring may not possess the qualifications you think they do. 52% of respondents in a ResumeLab survey admitted to embellishing their responsibilities to sound impressive, while 17% inflated their accomplishments. Without a solid evaluation method, distinguishing between qualified candidates and those who only look good on paper becomes significantly harder.
4. Slow hiring processes
Traditional hiring is notoriously slow, especially in large organizations with numerous applicants. With 71% of job seekers citing lengthy processes as a top reason for abandoning a hiring process, reviewing hundreds of resumes and conducting multiple interview rounds discourages candidates and wears out hiring managers - making top candidates go to companies with more efficient processes.
5 benefits of skills testing
Skills testing addresses the flaws in traditional hiring, delivering impressive hires that drive productivity.
1. Comprehensive, objective hiring data
Rather than making decisions based on assumptions, skills testing provides measurable, objective insights. LinkedIn data shows that hirers leveraging skills data are 60% more likely to find a successful hire. Comprehensive hiring data ensures a fairer, more consistent evaluation process.
2. Accurate hiring decisions
According to a Leadership IQ study, 46% of new hires "fail" within the first 18 months. Skills testing's objective evaluation method eliminates bias in interviews, provides realistic candidate performance reports, and leads to happier, long-term hires.
3. Fast, cost-efficient hiring cycles
Skills testing streamlines hiring by quickly filtering out unqualified candidates. Walmart cut their time-to-hire from 14 days to 7 days using Vervoe's skills tests. The cost of a wrong hire can be up to 2.5x salary - Vervoe's assessments help identify the best people at under $100 per hire.
4. Improved candidate experience
74% of candidates consider the ability to demonstrate their skills a key differentiator in hiring. Companies using Vervoe's assessments experience a 97% candidate completion rate - among the highest engagement rates in the industry.
5. Stronger workforce
50% of respondents in a Workday survey expect increased profitability after transitioning to a skills-based approach. Skills testing attracts employees who are better equipped, more productive, and aligned with the actual demands of the role.
Types of skills tests
Several skills tests are available, depending on what job qualities you're assessing. Most pre-employment assessments combine multiple types for a well-rounded evaluation.
1. Technical skills tests
These assess the hard skills essential for a specific role, focusing on job-related expertise. For example, a financial analyst's test might evaluate proficiency in Excel, financial modeling, and risk analysis.
2. Cognitive ability tests
These focus on general reasoning and problem-solving skills - strong indicators of a candidate's ability to adapt and learn. Common types include numerical reasoning, verbal reasoning, pattern recognition, and memory tests.
3. Job simulations
Candidates complete real-world problems identical to situations they will likely face on the job. This provides direct insight into how well they can handle the role's demands and leads to better alignment and reduced turnover.
4. Soft skill evaluations
Using behavioral questions or psychometric assessments, these measure communication, teamwork, and leadership traits. They should be interpreted carefully to avoid bias or ethical concerns.
5. Situational judgment tests (SJTs)
SJTs assess soft skills in job-specific contexts by presenting candidates with hypothetical workplace challenges. They're typically multiple-choice, providing structured scenarios for easy grading and scalability.
How to create and conduct an effective skills test
Crafting the right series of questions should be a collaborative process between the recruiting team and the team hiring the new employee.
1. Define the key skills to assess
Identify the exact skills required for the role by reviewing the job description and conducting a job task analysis - interviewing employees in the same role or related management positions.
2. Craft test questions
Select or create questions that mirror the job in a realistic way. Mix hard and soft skills, organizational values, and ethics. Use a variety of formats - spreadsheets, video responses, and multiple-choice - for in-depth insights.
3. Structure questions for efficient flow
Arrange questions to flow seamlessly - beginning with easier, highly relevant questions and increasing the challenge as the test progresses. Customize questions to fit the role level you're hiring for.
4. Set scoring criteria
Clearly define your benchmarks. Note what successful and poor responses look like for every question, then train your software to identify and score them accordingly for a fair, consistent evaluation process.
5. Pilot and refine tests
Conduct a pilot test with a small group or your hiring team before rolling it out to candidates. Regularly reassess and update the test to align with evolving hiring needs.
At what stage of the hiring cycle should you implement a skills test?
Timing is everything. Skills tests can be used at various stages of the hiring cycle, each with advantages and disadvantages.
1. Early stage (Pre-screening)
Every applicant completes the skills test first, and their results determine whether they continue. Harvard Business Review research shows this "efficiently weeds out the least-suitable applicants, leaving a smaller, better-qualified pool." It also fosters diversity hiring.
2. Mid-stage (After initial screening)
Candidates complete an initial shortlisting process before taking the skills test. This ensures only the most promising candidates are assessed, though it can reduce diversity and miss equally skilled candidates without conventional credentials.
3. Final stage (Post-interview)
Candidates complete skills tests after a successful interview round. Most common for senior leadership roles to validate proficiency before a final hiring decision. The downside is it can slow hiring down by relying on multiple rounds of traditional screening first.
Understanding skills test validity
Skills test validity measures how accurate a skills test's evaluations are with respect to the skills it was designed to assess - important for accurate hiring and EEOC compliance.
1. Face validity
Whether a test appears effective at first glance. When candidates deem a test relevant to the job, they're more enthusiastic about engaging with it.
2. Construct validity
Whether a test actually measures the skills it claims to evaluate - what people mean when they ask if a test is "validated" or has "psychometric validity."
3. Content validity
Whether the test covers the full range of skills it's supposed to measure - a healthy balance of all required hard and soft skills an employee will need to produce maximum results.
4. Predictive validity
High predictive validity means test scores accurately predict future job performance. A skills test with poor predictive validity leads to poor hiring decisions because top scorers may not have adequate job fit.
5 tips to consider for effective skills testing
1. Evaluate candidates at the initial hiring stages
Assessing candidates early streamlines your process. Smart algorithms and AI tools can turbo-charge candidate assessments by scoring results quickly and removing human bias from the equation. Candidates are ranked on performance, not filtered against arbitrary benchmarks.
2. Align skills tests with job requirements
Ask questions clearly relevant to the role. Cover every aspect of the job, balancing technical expertise with problem-solving, adaptability, communication, and other interpersonal skills.
3. Keep tests engaging and efficient
Unnecessarily long or complex tests lose quality candidates. Create skills tests that are concise, interactive, and relevant to maintain engagement and improve completion rates.
4. Continuously refine and update tests with gathered data
As your company grows, modify your tests accordingly. Regularly review test performance and scoring benchmarks, and incorporate candidate feedback to improve the assessment process.
