Case Study: Wish achieves a 96% improvement in hiring and scales engineering faster with HackerRank

WISH - Customer Case Study

Wish, a mobile e-commerce platform serving over 300 million users and 500,000 merchant partners, needed to rapidly scale its engineering organization. Their three-person recruiting team spent excessive time sourcing candidates who often lacked required skills, and relied on untrackable PDF coding challenges that allowed plagiarism and made technical assessment unreliable.

By adopting HackerRank’s CodeScreen automated assessments with custom questions and insight-driven prioritization, Wish narrowed the candidate pool to truly qualified applicants and freed engineers from manual review. The change cut hiring time dramatically—moving from 4 months and zero hires to 1 month and five hires—delivering a 96% improvement in the hiring process and better, code-based hiring decisions.
