Woven is an automated technical assessment that focuses on experienced developers. Instead of just automating scoring, Woven's certified engineers assess candidate work. This allows for unique scenario types, such as Github Pull Request Reviews and Systems Design. This creates a more positive candidate experience for Senior Engineers in high demand, which reduces drop-off by half compared to automated assessments (40% vs. 15%). These more senior scenarios, which are more realistic, provide a better indication of who will pass the technical screens and the final round interviews. This saves engineers time. Interviews are often shortened by replacing take-home projects with woven customers and reducing the number of steps. NEW Detect ChatGPT cheating: Woven, the only technical assessment that has remote proctoring for all plans. Try ChatGPT with other platforms to see if their detection works!
