Where they pull apart

Mercer Mettl

Stands out: A large job-skills library, pay-as-you-go packaging language, and AI-based remote proctoring sit on one Mercer-branded cloud. The vendor cites 6,000-plus customers, 25 million-plus assessments a year, and 20-plus languages.

Watch out: There is no public per-test or per-seat table. You pick products on a form and wait for a quote. This is an assessment platform, not an ATS.

Not the right fit for

  • SMBs that want a published $142/mo test library they can buy online
  • Teams that only need a cognitive screen like Wonderlic Select

Wonderlic

Stands out: Unlimited candidate reports are included once you are on a plan, with no per-assessment overage called out in the FAQ. The majority of customers cited on the site are companies with 100 to 2,500 employees.

Watch out: There is no public per-test or seat table. Capterra's $6,000/user/year starting price is not a vendor rate. Support channels (chat vs phone vs CSM) vary by plan.

Not the right fit for

  • Teams that need a self-serve skills-test library they can buy tonight
  • Buyers who only want coding simulations rather than cognitive fit
