Mettl: The Online Skills Assessment Platform is Mettl was founded in 2010 as a talent assessment platform for large companies and small start-ups, and its services are used primarily for recruitment screening and employee competency tracking and training.

Mettl offers A "hands-on" assessment. Companies using its services on top can configure their own assessment questions so that candidates can test as they normally would.

One of the main differences of the platform is its "hands-on" assessment service. Companies can set their own assessments to see if a candidate can handle their day-to-day work. If a company wants to hire a developer, they can create a custom assessment to determine the candidate's programming skills. The Mettl algorithm then gives a score to the code in real time.
