Case Study: Flatiron Health achieves 430 hours saved per university hiring season with Codility

How Flatiron Health Saves 430 Hours Each University Recruiting Season

Flatiron Health, a healthcare technology and services company focused on accelerating cancer research and improving patient care, faced rapid growth and the need to hire skilled junior developers quickly with a very small recruiting team. With limited recruiting hours and engineering time, Flatiron Health sought an intuitive, time-saving platform — Codility’s online coding assessment — to create a structured, fair process for screening candidates and improve hiring velocity.

Codility provided automated coding tests, Code Playback to review candidates’ line-by-line coding, and an integration with Greenhouse to streamline workflows, giving hiring teams objective insights without heavy interviewer time. Using Codility, Flatiron Health achieved a 16:4:1 screens-to-onsites-to-offer ratio, saved 430 interviewing hours per university hiring season, limited technical interviewer time to four hours per week or less, and maintained a 100% retention rate among campus engineering hires.
