We’ve built an interview platform where candidates are assessed by working on real-world tasks—collaboratively—rather than answering standalone questions. It feels less like a test, and more like a working session.
For example, instead of asking an engineer to “explain system design,” we simulate a working environment where the candidate discusses trade-offs, builds incrementally, responds to suggestions, and iterates—just like they would on the job. The experience is dynamic and conversational, not a static test.
This mode of interviewing saves companies significant time. Today, these kinds of deep-dive interviews are conducted by busy engineers who spend 60–90 minutes per candidate. That adds up to thousands of hours per year in lost productivity—often from the same engineers whose time is already stretched thin.
Our platform delivers that same depth of evaluation—across job roles, from software to marketing to project management—without burning out the teams.
