'Data Science' is an often used umbrella term that, in reality, spans several different data and analytics competencies. To help organizations evaluate these skills, Correlation One developed the first standardized assessment platform exclusively for Data Science & Analytics (DSA) talent.

The C1 Assessment Platform consists of 1,000+ questions across dozens of data-oriented topics, including statistics, machine learning, SQL, hypothesis testing, experiment design, data wrangling & cleaning, qualitative data inference, and many more. The C1 Assessment Platform has been administered to over 50,000 DSA individuals around the world, and has been used to assess fit for a variety of analytical roles, from entry-level data analyst to product manager to data scientist to machine learning researcher. Correlation One works with you to develop custom tests that fit your specific DSA talent needs.

Greenhouse Recruiting's integration with Correlation One integration allows you to seamlessly use the two platforms together to add Correlation One assessments to your Greenhouse Recruiting interview pipeline.
