With more than 400 scientifically-backed skills tests, TestGorilla helps you spot and shortlist your best-fit candidates. Sign up for a free live demo to find out how.
Pre-employment testing gives you a way to objectively evaluate your job candidates. It reduces bias in the hiring process by focusing on applicants’ abilities instead of their background or education.
Pre-employment screening also makes it easy to see the big picture. Let’s say two candidates both say they have the French and collaboration skills you need. Testing enables you to confirm the extent of these skills, revealing who is best suited for the role.
There are many testing platforms out there, all with different features. Here, we compare TestGorilla and Codility so you can decide which would work best for your business.
More than 10,000 top brands and companies trust TestGorilla with their hiring needs. With more than 400+ tests, you can use the platform to test cognitive ability, culture-add, personality type, and much more.
Even if you’ve never worked with pre-employment testing before, TestGorilla makes it easy to get started. Just indicate what role you’re hiring for, choose from the suggested tests, add your own questions, and send out custom assessments in just a few clicks.
TestGorilla creates a secure, fair, and engaging experience for candidates, too. They can open the link to their assessment and complete it from any mobile device. You can even customize assessments with your logo and brand colors.
Comparing applicants is easier with TestGorilla, too – we provide clear rankings and benchmarks based on overall and individual test scores.
You can use TestGorilla to hire developers with custom coding challenges and to find the right managers, translators, editors, or almost any other professionals.
Codility is a platform primarily for hiring engineers, though it can also be used to assess developers, data scientists, technical interns, and software testers.
Codility has three main features:
CodeCheck provides enables users to build a CodeCheck test using ready-to-use tasks, based on the candidate's role, seniority, and the desired tech stack.
CodeLive is for interactive interviews, where users and candidates optimize or create code together
CodeEvent is for enterprises who want to create campus recruiting events, such as hackathons
Unlike TestGorilla, Codility doesn’t test cognitive ability, culture-add, personality, or other non-technical skills.
Pre-employment screening platforms with a large range of tests in their test libraries enable you to hire for every open position you have.
A large pool of tests also means you can evaluate candidates more fully, testing not just job-specific skills but communication, cognitive ability, and culture-add.
TestGorilla offers more than 400+ tests across many categories, including:
Cognitive ability
Personality and culture
Programming skills
Software skills
Languages
Job-specific skills, including those for developers, engineers, and other roles
Situational judgment
You can further customize your assessment with your own questions and preferred answer formats, such as file upload, multiple-choice, audio, text, and video.
TestGorilla offers localized websites in 12 languages, making it easy to assess and hire workers from around the world.
Codility offers more than 90 coding language and technology tests, including for HTML, JavaScript, jQuery, Python, C#, C++, Ruby, and many more, as well as development tools and frameworks. These tests are designed to evaluate candidates' problem-solving skills, applicable skills, and technical knowledge. Employers can also create custom questions in multiple-choice, multiple-response, and essay formats.
Codility has a recruitment library consisting of over 1000 tasks. Employers can mix and match tasks or create their own custom challenges. Coding tasks can take the form of tests, where applicants answer questions or custom coding challenges.
Codility also offers job-specific testing through its CodeCheck Template feature. Unlike TestGorilla, Codility doesn’t have tests to evaluate human language, personality, general cognitive ability, or non-technical skills.

Pre-employment testing quality control measures give you confidence in your test results.
These measures typically include extensive quality checks, frequent updates, regular updating of questions, and integration of customer feedback.
Every one of our tests is a group effort. We collaborate with a team of psychometricians, copywriters, subject-matter experts, and peer reviewers to ensure each test is scientifically backed and accurate.
Before any TestGorilla test goes live, it undergoes a 28-step quality-control process, which includes sample testing and reviews.
TestGorilla also proactively seeks and implements candidate and employer feedback to continuously update and improve the test library.
Codility doesn’t provide much detail about its quality-control process, though it does state it invests in R&D to create new task types, tests, and questions regularly.
Codility also has a Product Insights team (referred to as Codility Labs) that uses psychometrics, I-O psychology, and data science to improve and create new tests, and update their evaluation methods.

TestGorilla uses layers of anti-cheating measures to give you full confidence in your pre-employment assessment results. These include:
Taking regular webcam screenshots (with applicant permission)
IP-address monitoring, so only your intended applicant completes the test
A large question pool with questions replaced after they reach a threshold maximum exposure limit, reducing the risk of online leaks
Disabling copy-paste functionality during tests
Full-screen detection and time limits so applicants can’t search for answers online
With Codility, you can ask candidates to scan a photo ID and take a selfie to confirm their identity, however this is only available to users in the premium tier or as a standalone extra. The platform also logs their IP address, and an alert is raised if there is more than one location detected. Codility also uses a tool called Similarity Check to scrape the internet for leaked answers and replace them. However, if users share test questions manually or verbally, Similarity Check cannot detect this.
Codility also flags suspected ChatGPT and AI use on assessments.

Many pre-employment testing platforms use monthly or annual subscription models. Different tiers come with different features.
Some providers also offer free trials or free plans.
