Pre-employment testing provides a dependable measure of an applicant’s potential success in a specific role. It does so by measuring objective skills while avoiding the influence of unconscious bias.
It also streamlines the hiring process by removing the need to manually review tens – even hundreds – of ambiguous and subjective resumes.
Given the large range of pre-employment testing platforms available, it can be challenging to select the right one for your business. This article compares the features of two providers, TestGorilla and Plum, to help you make the best choice.

How does Plum work?
Plum focuses on behavioral assessments rather than job-specific skills.
Plum uses a single assessment to help employers make hiring decisions. It can be used during both the recruitment process and to manage growth opportunities for employees. The test model distinguishes 10 recurring patterns of thought, feeling, and behavior.
Customers complete an automated job analysis to identify each role’s behavioral requirements. Candidates then complete an assessment to measure their personality, problem-solving skills, and social intelligence.
Plum compares individual candidate results against the job analysis to rank candidates against the behavioral needs of the job.
TestGorilla vs. Plum: Test libraries
A pre-employment testing library should be comprehensive enough to cover a range of roles, enabling you to evaluate candidates with precision.
The platform also needs to review its tests regularly to optimize each question for identifying the best candidates.
TestGorilla’s test library
TestGorilla’s library features over 280 tests, all of which are completely customizable to meet the specific requirements of each role. Tests cover candidates’:
- Cognitive ability
- Language skills
- Personality traits
- Situational judgment
- Role-related skills, such as coding challenges for developer roles
You can choose from a wide range of answer formats, including multiple-choice, essay response, file upload, and video response.
International recruitment is also possible with TestGorilla, thanks to localized websites in 11 languages.
Plum’s test library
Plum offers a single assessment that measures 10 predetermined patterns of thought, feeling, and behavior.
Before an assessment, the platform conducts a job analysis to identify which behavior and personality traits are most valuable to success in the job.
Plum doesn’t offer job-specific skill tests or customized test questions to match business needs.

TestGorilla vs. Plum: Functionalities for hiring developers
Hiring developers is a unique process. It’s critical to evaluate applicants’ practical coding and software development capabilities, as well as soft skills like customer service.
Look for pre-employment tests that measure coding aptitude, debugging proficiency, and mobile-development framework skills. Pair these with personality tests to paint a more complete picture of the candidate and see how they’ll fit into your development team.
Hiring developers with TestGorilla
TestGorilla is an ideal assessment platform for hiring developers. We offer a variety of software skill tests, including:
- Coding languages

- Algorithmic-thinking challenges
- Debugging challenges
- Arrays proficiency
You can customize coding challenges to mimic real-life issues the candidate would face in your team.
Complement these with personality and customer service tests to assess the candidate’s communication skills.
TestGorilla can also assess the candidate’s familiarity with development frameworks, such as Django, React, and Angular, as well as other tools like CSS, Bash, and Git.
Hiring developers with Plum
Plum focuses on assessing personality and behavioral traits, so the platform doesn’t include coding or developer skills tests to measure capability in these specialized roles.

TestGorilla vs. Plum: Video interviews
Video interviews streamline your hiring process by removing the bulk of the logistics of scheduling in-person interviews.

TestGorilla’s video interviews
TestGorilla offers one-way video interviews with customizable options like setting a maximum response time. You and your hiring team can add comments to each interview, making it easy to collaborate efficiently.
TestGorilla also provides you the option to record candidates’ screens during certain tests, including coding challenges, which you can then play back later. This gives detailed insights into the candidate’s approach to problem-solving and time management.

TestGorilla vs. Plum: Candidate experience and company branding
A candidate’s first impression of your organization is crucial, so you need to curate a professional, user-friendly experience.
Including your company branding maintains a consistent image for the candidate, while a mobile-friendly platform is valuable to on-the-go applicants.
A platform that’s simple to use and offers applicants dedicated support as needed will contribute to a positive candidate experience.
The candidate experience with TestGorilla
TestGorilla’s pre-employment tests are each designed to take less than 15 minutes and candidates don’t need to create an account to complete them. These measures eliminate fuss and help ensure a high completion rate.
TestGorilla also provides ample branding options, including customized intro and outro videos, and adding your company colors and logo to all candidate communications.
The candidate experience with Plum
Plum creates a profile for every candidate that completes its assessment, but this carries Plum’s branding only. No mention is made of customization options to add the customer’s branding to candidate communications.

TestGorilla vs. Plum: Enterprise and startup friendliness
The right pre-employment testing platform will support your business needs whether you’re hiring for a large enterprise or a startup.
Startups may not hire constantly and need to be able to ramp support up and down accordingly. Meanwhile, enterprise businesses need solutions that integrate with other systems to avoid duplicate or unnecessary work.
Prioritize a platform that scales to support evolving recruitment needs, with features like ATS integration, candidate progress tracking, GDPR compliance, and API access.

TestGorilla vs. Plum: Quality control

Quality control for pre-employment assessments might include careful scientific development, pre-publishing reviews by multiple parties, regular question updates, and integration of customer feedback.
TestGorilla’s quality-control processes
TestGorilla views quality control as an ongoing and vital process. That’s why we employ a robust 28-step quality-control process for all tests before they launch.
This process involves collaboration with:
- Subject-matter experts
- Peer reviewers
- Sample testers
We actively solicit customer and candidate feedback and use this to improve our test library. We also retire questions after a set time to prevent overexposure or web leaks.
Plum’s quality-control processes
Plum’s assessment uses psychometric test theory to measure behavior and personality traits, so every candidate takes the same assessment. As a result, customers have no options to adjust or customize the assessment.
It is unclear from Plum’s website how often the platform reviews its assessment or updates the questions.

TestGorilla vs. Plum: Anti-cheating measures
Test scores are only useful when you can ensure that the results are fair. Effective anti-cheating measures ensure security and integrity for each test.
Some of the most common features that help prevent cheating include disabling copy-paste functionality, screen monitoring, and question randomization.
TestGorilla’s anti-cheating measures
TestGorilla offers a comprehensive range of anti-cheating measures. These include:
- Randomizing question order and retiring questions to avoid leaks

- IP-address monitoring to detect access attempts from multiple locations

These measures maintain the integrity of our test results and prevent candidates from seeking an unfair advantage.
Plum’s anti-cheating measures
Plum’s assessments require applicants to choose statements that are most or least like them to measure their behavior and personality traits – not job-specific skills. Because of this, Plum states there’s no incentive to cheat.
There is no mention on Plum’s website of common anti-cheating measures like question cycling or IP-address monitoring. The assessment also has no time limit.
Anti-cheating measures: Comparison chart at a glance

TestGorilla vs. Plum: Reporting and analytics
Detailed analysis of candidate responses and testing behaviors is crucial to enable you to gauge their potential performance accurately.
Your pre-employment assessment reports should be easy to understand and make it simple to compare and rank candidates.
Solid reporting and analytics also reduce the risk of unconscious bias by instead relying on measurable skills to rank results.

Plum creates a profile report that identifies each candidate’s top talents, such as adaptation or innovation. It also reveals the candidate’s work style and work preferences, such as favoring leadership roles.

If you’re new to pre-employment testing, some platforms even offer a free plan to help you get started.

Conclusion: TestGorilla vs. Plum
TestGorilla and Plum both offer behavior and personality tests to determine a candidate’s aptitude and potential. However, TestGorilla goes several steps further and includes job-specific skills tests, coding challenges, and substantial customization options.
TestGorilla’s extensive test library and focus on quality control improve hiring results for candidates from all backgrounds and for all roles. Pricing is transparent and easily adjustable to meet your business needs.
In contrast, Plum provides little detail on its quality-control processes and shares pricing information only by request.
Overall, TestGorilla is evidently the best platform to improve your hiring process with pre-employment screening.
