When the goal is to build a shortlist, Willo assesses every candidate consistently against the role's success criteria and surfaces who should progress, with the supporting evidence.


Willo gives your team a clearer picture of how candidates explain decisions and respond to situations relevant to the role, without creating a complex candidate experience.
Willo Intelligence helps shortlist candidate responses, giving your team the evidence and context behind every score.


Your team reviews the evidence together and decides who should progress.
Hiring teams use Willo across seasonal campaigns, emerging-talent programs and year-round recruitment. You can review more candidates before a live interview without increasing first-stage screening work at the same rate.

Willo fits teams that want AI to organize completed candidate responses against their own role criteria for human review. TestGorilla fits teams that want resumes, skills tests, custom questions and AI interviews scored into a ranked assessment result.
