Case Study: Telecommunication and IT Services Company achieves data-driven hiring and identifies high performers with Mercer Mettl

How they filtered out applicants based on their predicted performance with Mettl

Telecommunication and IT Services Company, a London‑headquartered telecom giant with a 110,000‑strong workforce operating across 30+ countries, needed to improve hiring for critical sales manager roles. Faced with the need for a robust resume filter that handled complex demographic conditions, better identification of predictive competencies, and performance analysis across diverse employee demographics, they engaged Mercer Mettl and its assessment suite (Mettl Personality Profiler, Customer Focus Test, and Mettl Critical Thinking Test) to build a data‑driven hiring approach.

Mercer Mettl used these assessments to create a competency blueprint via predictive validation and response‑style checks, then applied the model to screen applicants. The solution delivered faster, smarter resume filtering, a comprehensive report linking assessment scores to on‑the‑job performance, identification of probable high performers, and demographic performance analysis — enabling HR to more quickly focus on the right candidates and improve hiring accuracy and efficiency.
