Our recruiting teams remain responsible for all hiring decisions and are involved throughout the process. Depending on where you are located, you may have the right to request further information about how AI is used in our recruitment process, to opt out of AI-assisted review, to request a manual review of any decision made or to contest a decision.  Please contact us at [email protected] for any requests or questions.
