TestGorilla vs. Aon

Pre-employment testing is the best way to streamline your hiring process and ensure you get the right person for your open role every time. Test results provide deep insights into a candidate’s skills, cognitive ability, personality traits, and more. Objective criteria take the guesswork out of comparing unreliable resume claims and remove unconscious bias from hiring.

Choosing the right pre-employment screening platform is key to ensuring you get all of the benefits testing has to offer.

TestGorilla vs. Aon: Functionalities for hiring developers

Hiring developers requires assessing unique, highly technical skills. Pre-employment testing can identify a candidate’s skill level clearly and objectively. 

Look for platforms offering a range of coding languages and development framework tests. Features like code playback give additional insight into how each candidate approaches a challenge.

Hiring developers with TestGorilla

TestGorilla provides a library of more than 120 tests specifically measuring programming skills. These include tests for mobile and web-development frameworks and popular coding languages like Python and JavaScript. You can also add custom coding and debugging challenges to any programming test.

TestGorilla vs. Aon: Video interviews

Incorporating one-way video interviews and custom video questions into assessments help measure a candidate’s communication skills. 

One-way video interviews can also replace recruiter screening calls to save time. This feature can evaluate large pools of potential talent efficiently, helping you select the best candidates to invite for face-to-face interviews.

TestGorilla’s video interviews

TestGorilla enables user-friendly one-way video interviews, plus you can add video questions to any test. Candidates can record responses on any device, and you can limit responses to 30, 60, or 120 seconds.

TestGorilla vs. Aon: Candidate experience and company branding

Candidates are more likely to complete pre-employment testing if they believe the tests are reasonable and easy to use. Features that improve a candidate’s experience include limiting test length, providing a mobile-friendly platform, and ensuring access to support. 

Company branding features also help to provide unified candidate communication. These include integrating your company’s logo and brand colors into correspondence, as well as customized options like video intro and outro messages.

The candidate experience with TestGorilla

TestGorilla provides a seamless candidate experience. You can add your company logo and colors to assessments, as well as a custom intro or outro video. It’s also easy to create custom email communications to keep your candidates updated about their status in your hiring pipeline. We also now send out automatic emails when candidates complete assessments to give them assurance their assessments have been received. 

TestGorilla assessments take only 30-60 minutes to complete, which is less time-consuming than writing a cover letter for many candidates. 

Candidates are offered support directly to ensure they’re able to complete assessments to the best of their ability. Tests and assessments can be accessed on mobile devices and don’t require an account to log in. Candidates who complete an English-language assessment have the option to create a TestGorilla account to review their results.

TestGorilla vs. Aon: Enterprise and startup friendliness

Effective pre-employment testing platforms can cater to businesses of all sizes, from startups to large-scale enterprises.

TestGorilla vs. Aon: Quality control

Test results must be reliable and accurate to improve hiring decisions. You can determine a platform’s reliability and accuracy by examining its quality-control processes.

Look for measures like science-based question development, extensive quality checks, and adapting to feedback.

TestGorilla’s quality-control processes

TestGorilla’s hiring solution is backed by science. We put every test through a 28-step quality-control process before it’s published. Subject-matter experts, psychometricians, peer reviewers, and copywriters all contribute to quality reviews. 

TestGorilla continuously improves tests by soliciting feedback from customers and test-takers. Test questions are also retired after they have appeared a set number of times to prevent the possibility of web leaks.

Aon’s quality-control processes

Aon provides research-backed psychometric assessments.

According to Aon’s website, each test is subjected to robust assessment. However, Aon doesn’t define how it reviews its tests, nor does it describe its quality-control processes in detail.

TestGorilla vs. Aon: Anti-cheating measures

Anti-cheating measures ensure a level playing field for all candidates. 

These measures prevent candidates from researching answers during the assessment and identify when someone other than the candidate accesses a test. 

Common anti-cheating measures include limiting test time, disabling copy and paste, and logging the test-taker’s IP address. 

TestGorilla’s anti-cheating measures

TestGorilla confirms a candidate’s identity with IP address monitoring and regular webcam snapshots (with the candidate’s permission). 

TestGorilla also uses full-screen monitoring to identify when a candidate clicks outside the test window – and disables copy and paste to minimize the risk of candidates sharing questions.

Test questions are randomized within each test and drawn from a large pool of questions. This makes it less likely that candidates can prepare in advance. Questions are retired after a certain number of appearances to limit the impact of leaks. 

You also have the option to set test deadlines, which can prevent candidates from seeking outside help on assessments.

Aon’s anti-cheating measures

Aon offers optional virtual proctoring so you can monitor a candidate while they complete their assessment. 

Tests are subject to a time limit, but candidates can also take ungraded practice tests before their assessment without a time limit.

TestGorilla vs. Aon: Reporting and analytics

Reliable pre-employment testing software should enable you to compare candidate results easily and generate informative reports.

Additionally, the results in our PDF reports are broken down into skill categories, so you can see how well each candidate did in each category. 

With our advanced filters, you can also easily compare candidates using various factors – such as their test scores or answers to your custom questions.

Aon’s reporting and analytics features

Conclusion: TestGorilla vs. Aon

TestGorilla and Aon both offer a wide range of pre-employment assessments. Tests on either platform can measure cognitive ability, personality traits, and job-specific skills. Specialized tests like coding challenges are also available on both platforms.

Test reliability is vital to ensure your pre-employment testing correctly identifies the best candidates. TestGorilla thoroughly vets tests before they are published and continuously reviews questions to make sure they perform as intended. Aon provides limited details on how its tests are validated.

Another important factor in test reliability is a candidate’s potential to cheat on a test. TestGorilla provides robust anti-cheating measures that ensure results can be trusted. In contrast, Aon enables virtual proctoring only as an extra option.

TestGorilla’s flexible and transparent pricing also stands out for businesses that want to know upfront how much pre-employment screening software will cost.
