Warning to applicants about false job offers and fraudulent proposals

The VINCI group wishes to warn applicants about the online publication of false job offers for contracts abroad in the name of VINCI group companies. The authors of these offers fraudulently use the corporate names, brands and logos of VINCI group companies to deceive applicants, inducing them to reveal personal information and to pay money to obtain alleged services. Under no circumstances do VINCI group companies ask for candidates' bank details or any payment of money as part of their recruitment process. We therefore strongly recommend that applicants check the authenticity of job offers before responding to them.
