Fakten
Her I/O Psychology training covers the science recruiters actually apply: personnel selection, psychometric assessment, and how structured evaluation reduces hiring bias.
As an HRBP she sits inside the hiring process daily, from screening candidates to onboarding them, at a company with hundreds of employees across Puerto Rico.
She brings a bilingual, Latin American market perspective to resume and career advice, where norms differ from the US standard (photos, personal details, CV formats).
