Hiring managers and recruiters can use these assessments to make confident, data-driven hiring decisions while removing unconscious bias from the process.
But with a range of pre-employment testing providers to choose from, it can be hard to choose the right one for your business.

How does TestGorilla work?
TestGorilla is a top-rated pre-employment testing software that makes it easy to streamline your hiring process and find the best person for the job.
With over 300 tests to choose from, you can use TestGorilla to assess a wide range of a candidate’s skills and abilities, including culture-add, personality, programming ability, and cognitive ability.
TestGorilla also enables you to tailor each assessment to a specific role. This includes adding custom questions and one-way video interviews.
On TestGorilla’s user-friendly platform, you can quickly see and compare candidate results and identify top performers. You can also easily download and share reports with your hiring team and add notes to aid the decision-making process.

Plus, by focusing on the data, you reduce bias in your hiring process. This builds a more diverse workforce, fostering creativity and innovation while also improving employee productivity and engagement.
How does Interviewer.AI work?
Interviewer.AI is a video interviewing software that automates the candidate pre-screening process.
The platform uses a combination of skills and personality tests, resume scoring, and asynchronous interviews to help employers find the right person for the job. Its features include:
- WorkMap, a skills assessment that measures relevant candidate competencies against the primary skill set needed for a job.
- Resume scoring, which uses AI-powered features to measure how closely candidates’ resumes match the relevant job description.
- An interviewing platform that uses AI expression and voice analysis as well as natural language processing to score candidates based on the content and delivery of their responses.
Interviewer.AI combines the results from these three tools to give an overall score for each candidate. It also provides specific insights into their cultural fit, communication skills, and professionalism.
TestGorilla vs. Interviewer.AI: Test libraries
When comparing pre-employment testing providers, prioritize one with an extensive test library. The more skills you can test for, the more precisely you can tailor an assessment to the role you’re hiring.
A good test library includes personality, aptitude, culture-add, and job-specific skills tests.
TestGorilla’s test library
TestGorilla offers more than 300 tests that enable you to assess candidates’ personalities, coding abilities, situational judgment, cognitive abilities, cultural fit, languages, and job-specific skills.
These tests are available via 11 localized websites, including Japanese, Spanish, and French, to help you find the best person for the job regardless of their location.
What’s more, TestGorilla assessments are highly customizable. You can edit test questions and add your own, and even choose how candidates answer, including via video, multiple-choice, open text, and file upload.
Interviewer.AI’s test library
Interviewer.AI offers two levels of tests: job-specific skills tests and asynchronous video tests.
WorkMap assesses essential skill sets for the role during candidate interviews. It can create assessments for over 20 job functions, like Finance and HR, to measure skills including analytical reasoning, attention to detail, problem-solving, and culture fit.
However, Interviewer.AI doesn’t offer tests to assess language or role-specific skills, like coding ability.
WorkMap can autogenerate interview questions based on specified skills or users can pick their own from the question bank. Candidates respond to these by registering the degree to which they agree with the statement.
At the second level, Interviewer.AI’s one-way video assessments use AI to evaluate soft skills like professionalism, sociability, communication, and energy.
The platform can also transcribe and analyze video responses in five languages, including English, Mandarin, and Spanish.

TestGorilla vs. Interviewer.AI: Functionalities for hiring developers
If you’re hiring software developers, you need to find applicants with strong technical skills, including programming and coding proficiency in the specific languages your company works with.
When choosing a pre-employment testing provider, look for one that includes role-specific tests on coding, debugging, or language-specific concept challenges.

TestGorilla vs. Interviewer.AI: Video interviews
Video interview features like custom video questions and live interviews offer useful insights into candidates’ communication and presentation skills.
Asynchronous, or one-way, video interviews are a great way to pre-screen candidates before deciding who to interview in person.
Both TestGorilla and Interviewer.AI offer video interview features.
TestGorilla’s video interviews
With TestGorilla, you can add up to 20 custom video interview questions to each assessment. These are a great way to engage your candidates and add variety to their assessment experience while learning more about their communication skills.
You can set a maximum length for candidates’ responses to keep them short and sweet, and later add your comments to videos to assist with the hiring process.
You can also set the number of times candidates can re-record their responses and we log their attempts for your records.
Interviewer.AI’s video interviews
Asynchronous video interviews are a key feature of Interviewer.AI. Users can select from the preset interview questions or add their own to assess specific skills or traits.
The platform limits the total interview time to 10 minutes to keep candidates engaged and accommodate for slower internet connections.
The platform then uses AI to transcribe and analyze candidates’ responses and score their communication, professionalism, energy levels, and sociability.
Hiring managers can review video responses, or just read the transcripts, and assign their own scores.
It’s unclear how many attempts candidates have to record their responses and whether Interviewer.AI tracks their number of attempts.

TestGorilla vs. Interviewer.AI: Quality control
You rely on pre-employment testing results to make important hiring decisions, so it’s essential that they’re accurate and reliable.
That’s why you need to look for strong quality control measures when choosing a pre-employment testing platform, including rigorous pre-launch testing and frequent question replacement.
TestGorilla’s quality-control processes
TestGorilla tests undergo a rigorous 28-step quality control process that harnesses the expertise of psychometricians, subject-matter experts, peer reviewers, and copywriters.
We also welcome and implement user feedback to enhance the testing experience for both customers and candidates.
What’s more, our proprietary algorithms review tests on a rolling basis to identify potential improvements.
TestGorilla replaces questions after a certain number of uses to avoid overexposure. This means you can rely on your assessment results to help you hire the right person.

Interviewer.AI’s WorkMap platform bases its skill sets on industrial and organizational psychology, as well as industry knowledge.
Interviewer.AI says its video response assessments and resume scoring have an accuracy of above 80%. Interviewer.AI constantly reviews its technology to improve accuracy.
However, it’s unclear whether Interviewer.AI regularly replaces questions or incorporates user feedback in its quality control.

TestGorilla vs. Interviewer.AI: Anti-cheating measures
Candidates that cheat during pre-employment testing gain an unfair advantage over others and could even invalidate your results by skewing the data.
Strong anti-cheating features reduce the chance of this. Look for measures like timed assessments, candidate webcam monitoring, and IP-address logging to ensure your candidates’ test results are honest and reliable.
TestGorilla’s anti-cheating measures
TestGorilla offers a range of security features to prevent cheating. These include disabling copy-paste and randomizing the question selection to limit the opportunity for candidates to share questions and answers.
We also log candidates’ IP addresses during the assessment to ensure that only the invited candidate can complete it.
Plus, features like 30-second webcam shots (with candidates’ permission) and full-screen mode detection effectively discourage candidates from leaving the assessment to research a question or answer.
Interviewer.AI’s anti-cheating measures
There is limited information available about Interviewer.AI’s anti-cheating measures.
Its assessments are conducted during asynchronous video interviews which require the candidate to appear on screen, so recruiters can confirm their identity.
