Acme Co. screens and places candidates at other companies including those fictionally-named Bravo and Tec2.
Candidate J. Doe applies for a role with Bravo, including a resume citing a lot of experience on a project at Tec2.
Acme learns that this is a serious misrepresentation, through a combination of its own knowledge resulting from the partnership with Tec2 and J. Doe's performance on interview questions that should have been easy if the resume was truthful.
Beyond simply declining to hire the candidate, does Acme have any further ethical responsibilities?
