Pre-employment online testing saves recruiters time by honing in on the most suitable candidates and reducing the risk of a costly mis-hire. This guide covers what to look for in a testing platform, then breaks down 12 of the best options available today.
An online testing platform is software that helps recruiters, HR teams, and managers to assess candidates' suitability for specific roles. It does this by simplifying the process of making and conducting pre-employment testing.
Conducting pre-employment tests is the best way to assess candidates. It’s fairer and more comprehensive than relying on traditional methods and therefore can increase your chances of making a successful hire.
The benefits extend beyond the assessment process as it reveals information that can guide new hires’ onboarding and professional development.
Including online testing in recruitment and hiring processes gives HR teams and recruiters multiple benefits.
Online tests offer an objective way to assess candidates' suitability for a job. They also help to identify a candidate’s potential fit within a team or wider organizational culture.
Evaluating candidates using resumes, references, and interviews can be inherently subjective. Resumes show candidates' self-reported accomplishments, references can be frustratingly nondescript, and job interviews are notoriously open to unconscious bias.
Pre-employment testing removes the potential to be influenced by things that aren't related to the position, or be swayed by a candidate's unwarranted confidence.
Well-constructed online tests built on scientific foundations are highly reliable. The results from these tests are a powerful resource for validating candidates' skills, assessing their knowledge, and checking suitability for a role.
The objective nature of this type of testing enables recruiters to make more informed decisions during the hiring process. Having candidates take pre-employment tests can also help recruiters verify the accuracy of what candidates tell them.
Using pre-employment tests can help you build a more complete picture of each candidate. The most effective tests measure various aspects to evaluate how well candidates align with a specific set of requirements.
For example, if you were looking for an entry-level Python developer, you could use an online test to confirm applicants' coding ability. Or if you were hiring a warehouse picker, you could assess their ability to plan and execute warehouse picking activities accurately.
As well as measuring job-related competencies, online testing can also assess candidates' soft skills, including their ability to learn, and their personality. These insights help you understand critical factors, such as whether individuals can communicate effectively, and if they'll be able to gel with existing teams.
Reducing bias, improving accuracy, and getting a more complete picture allows recruiters to make better-informed decisions.
The objectivity of online testing helps you identify candidates whose skill sets and personalities match your requirements. And because pre-employment assessments delve deeper than resumes, you can use these findings to help new hires hit the ground running when they start. This increases your chance of making successful long-term hires.

Using online testing to make the right hiring decision hinges on getting reliable, actionable insights. To ensure the testing platform you choose can give you the best results, there are several important factors to look for.
A key benefit of using an online testing platform is that it saves time by handling the heavy work involved in creating and conducting pre-employment assessments. So, the platform you choose must be easy to use.
Look for a platform with a user-friendly interface that streamlines the process from test construction to reporting results.
The best online testing platforms offer a range of tests that assess candidates across many different characteristics, such as their:
Personality
Behavioral traits
Cognitive ability
Technical proficiency
Emotional intelligence
Problem-solving skills
Ethics and values
When choosing an online testing platform, look for a solution that can be tailored to suit your unique requirements. Including custom questions when you screen candidates makes it easier to pinpoint those with attributes you value. It also avoids wasting time on those who don't fit the bill.
If you plan to use online tests in the early stages of your hiring process, it's important that candidates can complete them in a reasonable length of time. Online tests are convenient, but assessments that take too much time to complete can risk discouraging some applicants.
Understanding online tests shouldn't be a test in itself. Pay attention to how platforms present results. The best testing platforms consolidate detailed assessment results into digestible reports. Having clear, easy-to-understand results facilitates effective comparison, allowing you to focus on identifying the best people for your positions.
Cost shouldn't be the sole deciding factor, but it's still important. Some testing platforms base their pricing on the volume of candidates, whereas others have fixed rates with varying features. Your budget is undoubtedly important, but also consider the variety of positions you hire for and the number of candidates they attract.
The best platform depends on your hiring needs. TestGorilla is the strongest all-around option, with 350+ validated tests covering technical skills, cognitive ability, personality, and culture add. If you hire primarily for developer roles, HackerRank is the specialist. For high-volume frontline hiring, ThriveMap's bespoke job simulations are purpose-built for that use case.
Focus on five factors: the range and quality of available tests, how well the platform integrates with your existing ATS, whether the assessments are scientifically validated, candidate experience (including mobile-friendliness and test length), and pricing structure. Platforms that charge per candidate work well for occasional hiring, while subscription models suit teams that recruit regularly.
Yes, when the assessments are built on validated methodologies. Science-backed pre-employment tests are better predictors of job performance than resume screening or unstructured interviews. Look for platforms that use I/O psychology principles, peer-reviewed test development, and anti-cheating measures to ensure reliable, objective results.
Pricing varies widely. Some platforms like TestGorilla offer free plans with limited features, with paid plans starting around $142 per month. Others charge per candidate (from $5 to $50 per assessment) or offer enterprise pricing on request. Consider your hiring volume and whether you need a broad test library or specialist assessments when comparing costs.
Most established platforms integrate with major applicant tracking systems, either through native integrations or APIs. Criteria offers the widest ATS coverage with 60+ integrations, and platforms like TestGorilla and eSkill also connect with most major systems. Before committing, confirm that your specific ATS is supported and that results flow directly into candidate records rather than requiring manual data entry.
Hiring professionals can reap invaluable benefits by using an online testing platform – but only when they choose the right one.
There's no one-size-fits-all solution for testing candidates online, so the best way to ensure positive outcomes is to weigh up each option against your specific hiring needs. Making the right decision will enable you to effectively and efficiently assess and compare your candidates without bias, leading to better hires and fewer costly mis-hires.
In today's competitive landscape, online tests are becoming essential hiring tools. TestGorilla ensures that businesses of all sizes can benefit from it by offering flexible plans that scale with your hiring needs.
