Case Study: Citi achieves a 50% reduction in introductory interviews and faster tech hiring with Codility

How Citi Optimized their Tech Hiring Process with Codility

Citi, a global financial services leader, needed a way to screen programming candidates that preserved the quality of in-person interviews while reducing the time engineers spent on initial assessments. To meet this goal, Citi adopted Codility to introduce automated programming tests as the first step in their tech hiring process.

Codility provided a standard, language-flexible test library to automatically evaluate candidates’ programming and problem‑solving skills; only those who demonstrated sufficient aptitude progressed to in-person interviews. Using Codility, Citi cut the number of introductory interviews conducted by hiring managers by 50%, allowing teams to focus onsite time on the most promising candidates.
