What is Mercer Mettl?

Mercer Mettl is a leading skills assessment platform that empowers companies to efficiently screen and interview software engineering talent. It specializes in online coding tests and structured technical interviews, helping employers identify the best developers through real-world programming challenges.

How Mercer Mettl works 

The Mettl Assessment Platform is an all-in-one, cloud-based tool that enables organizations to assess the job-specific skills, personality traits, and behavior characteristics of both candidates and current employees. 

Beyond pre-employment assessments, Mercer Mettl offers online assessments for lateral and campus hiring.

1. Create an assessment

Recruiters can choose from a variety of pre-built tests or create a customized assessment for the role you’re hiring for. Mercer | Mettl provides a wide range of pre-built tests covering technical skills, cognitive abilities, and soft skills. The platform allows for high customization, enabling recruiters to tailor assessments to specific job roles and requirements.

2. Invite candidates 

To invite candidates to a test in bulk, Mercer | Mettl utilizes Test-Taker Banks, which contain the relevant data for multiple test-takers. Here’s how to manage them:

• Creating a Test-Taker Bank: Navigate to the “Test-Taker Banks” page by clicking on the “Account Settings” icon and selecting “Manage Test-Takers” > “Test-Taker Banks.” Provide a unique name for each bank and select the appropriate language. Click on the “Add” button to create the bank.
• Adding Candidates: Once the bank is created, click on “View Candidates.” Here, you have two options:
  Add New Candidate: Click on “Add New Candidate,” fill in the relevant details (mandatory fields are marked with asterisks), and click “OK.” Repeat this process to add more candidates manually
  Bulk Upload Candidates: Click on “Bulk Upload Candidates.” Choose the appropriate template language and select either “Single Candidate Bank” or “Multiple Candidate Bank” based on your needs. Download the template, fill in the candidate details, and upload the file. If there are any errors in the data, an error file will be generated to help you rectify them

3. Test-taker registration and access

After candidates are added to a Test-Taker Bank, they will receive an email invitation to take the assessment. The email will contain a link to the test, and candidates can access the test based on the settings configured by the recruiter.

Recruiters can customize the test link settings, including access time, proctoring features, and other parameters to ensure a secure and fair testing environment

4. Proctoring and anti-cheating measures

To maintain the integrity of assessments, Mercer | Mettl employs advanced AI-driven proctoring. This includes real-time monitoring, identity verification, and automated fraud detection.

Additionally, the platform offers human proctoring options for high-stakes exams. The “Super Proctor” feature allows for oversight of multiple proctors, ensuring consistent enforcement of assessment guidelines

Is Testlify a better alternative to Mercer Mettl?

Testlify and Mercer Mettl are both strong contenders in the skills assessment space, but which platform is better ultimately depends on your hiring goals, team structure, and candidate evaluation strategy. That said, Testlify emerges as the stronger alternative and here’s why:

• Broader test coverage: Testlify offers a significantly larger test library of over 3,000 assessments tailored to 4,500+ job roles across 50+ industries. Mercer Mettl’s library, while extensive, contains only 400+ tests in comparison. If you require assessments for niche roles or want a one-stop library for almost any skill, Testlify provides far more options out-of-the-box.
• Advanced conversational interviews: Testlify’s conversational AI interviews provides a holistic view of candidates’ problem solving skills. In contrast, Mercer Mettl relies on more traditional assessment formats and a separate video interviewing tool. Testlify’s multi-format approach offers a versatility that Mettl currently cannot match in-platform.
• Extensive ATS integrations: Testlify supports 100+ ATS and HR tool integrations, giving it a clear advantage over Mercer Mettl’s 16+ integrations. This makes Testlify more adaptable for teams that rely on integrated hiring pipelines and automated workflows.
• AI insights: Testlify’s AI-generated overviews and benchmarking analytics help recruiters evaluate candidates faster and with more confidence. Mercer Mettl, while offering detailed scorecards, lacks AI summaries, requiring manual interpretation of results.
