Mercer | Mettl

Mercer | Mettl dominates the global corporate hiring and talent management sector. It is a massive, highly scalable assessment platform utilized by enterprise HR departments to test thousands of candidates simultaneously for cognitive ability, coding skills, and behavioral traits before they are ever granted an interview. The platform is famous for its heavily automated, AI-driven proctoring technology. If a university is administering a massive entrance exam to 10,000 students remotely, paying human proctors is too expensive. Mettl's AI monitors the student's webcam and microphone, automatically flagging suspicious behavior—such as the student looking away from the screen frequently, a second face appearing in the frame, or a smartphone being detected on the desk. Beyond basic multiple-choice quizzes, it offers incredibly rich simulators. A call center can use Mettl to test a candidate using an interactive audio simulator, requiring the candidate to verbally de-escalate a simulated angry customer, while the software analyzes their tone and response time, providing far deeper insights than a traditional resume.
