What is CoreEval?

A better way to hire better candidates. CoreEval features project-based take-home interviews that uncover how candidates perform the day-to-day tasks of modern technical teams.

The 2 part byteboard assessment tests skills such as code quality, collaboration, technical communication, productivity and working within an existing codebase.An illustration showing a project with benefits

Technical Reasoning Exercise

Our assessments are open-ended, so there are multiple paths and no “correct” answer, so you can see how they would work in the real world.

The technical reasoning exercise is a collaborative document writing effort.

Code Implementation Exercise

What can you expect from a new hire’s first 90 days? By putting the code test in the context of a project, candidates are required to think about the problem holistically.
