Coding, Software & Engineering Technology & Engineering AI Simulations
Validate core software developer skills with hands-on coding simulations. Assess candidates and upskill teams using live coding challenges, pair programming, and system design scenarios. Test proficiency in Java, Python, C#/.NET, JavaScript, React, and all the most popular languages for front-end and back-end developers. Go beyond algorithms to see how developers debug legacy code, collaborate on code reviews, and articulate technical decisions. Listen to them explaining things live in calls and interact with colleagues and stakeholders. The most effective way to predict job performance, screen for quality, and build a world-class engineering team.
